The way we implemented undoing transactions was horrible. We'd process
the original transaction, but with a reversed=true flag. That meant we
had to keep track of the 'reversed' flag everywhere, and use ternaries
like insert = reversed ? op.remove : op.insert; all over the place to
access transaction operations. Redo then worked by reapplying the
transaction. We would verify that this was OK by tracking whether the
transaction was in an applied state or an undone state.
This commit makes it so every transaction can only be applied once. To
undo, you obtain a mirror image of the transaction with tx.reverse(),
then apply that. To redo, you clone the original transaction with
tx.clone() and apply that. All the code that had to use ternaries to
check whether the transaction was being applied in reverse or not is
gone now, because you can only apply a given transaction forwards,
never in reverse.
Bonus:
* Make ve.dm.Document's .completeHistory a simple array of
transactions, rather than transaction/boolean pairs
* In the protection of double application test, clone the example
document properly; it modified ve.dm.example.data, which was "fine"
because it ran .commit() and .rollback() the same number of times

Code with a similar purpose was added in 568e0e5701 but got lost
when some things were moved from ve.Surface to ve.ce.Surface in
5012ed10.
Initializing the selection at (0,0) was known to cause problems before,
and since 789d0caf09 breaks editing of empty documents: typing in an
empty document begins in an inline slug, but SurfaceObserver doesn't
notice typing in an inline slug unless the ce.Surface pawns it, which
is OK because insertions in slugs are always pawned, but the pawning
logic believes the cursor to be at offset 0 where there is no slug
(it's at offset 1) and so it doesn't pawn.
Bonus: update tests and add descriptions for dm.Surface.change tests

This isn't a problem when using the UI buttons as they get disabled
but the command keys can still trigger these methods.
Also fix hasPastState to include check for small stack. This fixes

Whenever there is more than 2 spaces (except the extra space
on a continued line of an @ tag, or the extra space on a
continued line of a list item) it causes a <pre> context.
Removed both spurious spaces that caused a <pre> and ones that
didn't but looked like it could.
When making an ordered or unordered list, the first item needs
to be on a new line and in block context (e.g. an empty line
before it). Otherwise it is rendered inline as 1. Foo 2. Bar
(such as in #rebuildNodes where both the ordered and unordered
lists were broken).

Now comparing annotations in surface to insertionAnnotations
by comparable object to trigger pawn trick. Adding annotations
correctly to placeholder.
dm.Surface change method now uses setInsertionAnnotations()
and passes the AnnotationSet from offset-1. The set is cloned.
Added ve.ce.Surface.areAnnotationsCorrect() to compare either
annotations to the left or right to the insertionAnnotations.
Also use compareTo() and getComparableAnnotations() rather than
comparing by name, and fix SurfaceFragment.annotateContent() to
actually be selective when clearing rather than clearing everything.

The EventEmitter API we inherited from Node.js and then bastardized was
getting awkward and cumbersome. The number of uses of ve.bind was getting
out of control, and removing events meant caching the bound method in a
property. Many of the "features" of EventEmitter wasn't even being used,
some causing overhead, others just causing bloat. This change cleans up
how EventEmitter is used throughout the codebase.
The new event emitter API includes:
* emit - identical to the previous API, no longer throws an error if you
emit error without a handler
* once - identical to the previous API, still introduces a wrapper* on -
compatible with the previous API but has some new features
* off - identical to removeListener in the previous API
* connect - very similar to addListenerMethods but doesn't wrap callbacks
in closures anymore
* disconnect - new, basically the opposite of addListenerMethods
Another change that is made in this commit is mixing in rather than
inheriting from EventEmitter.
Finally, there are changes throughout the codebase anywhere
connect/disconnect could be used.

By removing the transaction listeners from surface fragments we
no longer have to make sure they are always manually destroyed.
In order to retain the functionality of having fragments update
with transactions elsewhere we keep a pointer to a place in the
new complete history stack in the surface. The complete history
stack records all transactions, even undone ones.
Whenever getRange is called we replay all transactions in the
complete history (in the correct order) since the fragment was
last updated.
Also in this commit:
* Updated Format/IndentationAction to test undo(). This increases
coverage of surface fragment behaviour.
* .range is always accessed by .getRange now, although as an
optimisation we can use the noCopy mode when we a sure the
returned range will not be modified.
* Added undo test to .update (previously .onTransact)

Created an IndexValueStore class which can store any object and return
an integer index to its hash map.
Linear data is now stored in ve.dm.LinearData instances. Two subclasses
for element and meta data contain methods specific to those data types
(ElementLinearData and MetaLinearData).
The static methods in ve.dm.Document that inspected data at a given

AnnotationSets (which are no longer OrderedHashSets) have been moved
to /dm and also have to be instantiated with a pointer the store.

The normalize method doesn't need to be explicitly called anymore because there's not any code that changes the properties of a range directly anymore.
A good way to prove it's not needed anymore is to move the normalization logic to the constructor and then add "console.log(this.from <= this.to );" to the normalize method - you will find that it's never actually doing anything at all because the range was normalized by the constructor.
ve.Range
* Moved normalization logic to constructor
* Removed calls to normalize method
* Removed normalize method
* Simplified documentation for flip method
* Whitespace fixes
ve.Document, ve.dm.Transaction, ve.dm.Surface, ve.dm.Document, ve.ce.Surface

Differences fixed:
* Variadic arguments are like @param {Type...} [name]
instead of @param {Type} [name...]
* Convert all file headers from /** to /*! because JSDuck tries
to parse all /** blocks and fails to parse with all sorts of
errors for "Global property", "Unnamed property", and
"Duplicate property".
Find: \/\*\*([^@]+)(@copyright)
Replace: /*!$1$2
* Indented blocks are considered code examples.
A few methods had documentation with numbered lists that were
indented, which have now been updated to not be intended.
* The free-form text descriptions are parsed with Markdown,
which requires lists to be separated from paragraphs by an
empty line.
And we should use `backticks` instead of {braces} for inline
code in text paragraphs.
* Doc blocks for classes and their constructor have to be
in the correct order (@constructor, @param, @return must be
before @class, @abstract, @extends etc.)
* `@extends Class` must not have Class {wrapped}
* @throws must start with a {Type}
* @example means something else. It is used for an inline demo
iframe, not code block. For that simply indent with spaces.
* @member means something else.
Non-function properties are marked with @property, not @member.
* To create a link to a class or member, in most cases the name
is enough to create a link. E.g. Foo, Foo.bar, Foo.bar#quux,
where a hash stands for "instance member", so Foo.bar#quux,
links to Foo.bar.prototype.quux (the is not supported, as
"prototype" is considered an implementation detail, it only
indexes class name and method name).
If the magic linker doesn't work for some case, the
verbose syntax is {@link #target label}.
* @property can't have sub-properties (nested @param and @return
values are supported, only @static @property can't be nested).
We only have one case of this, which can be worked around by
moving those in a new virtual class. The code is unaltered
(only moved down so that it isn't with the scope of the main
@class block). ve.dm.TransactionProcessor.processors.
New:
* @mixins: Classes mixed into the current class.
* @event: Events that can be emitted by a class. These are also
inherited by subclasses. (+ @param, @return and @preventable).
So ve.Node#event-attach is inherited to ve.dm.BreakNode,
just like @method is.
* @singleton: Plain objects such as ve, ve.dm, ve.ce were missing
documentation causing a tree error. Documented those as a
JSDuck singleton, which they but just weren't documented yet.
NB: Members of @singleton don't need @static (if present,
triggers a compiler warning).
* @chainable: Shorthand for "@return this". We were using
"@return {classname}" which is ambiguous (returns the same
instance or another instance?), @chainable is specifically
for "@return this". Creates proper labels in the generated
HTML pages.
Removed:
* @mixin: (not to be confused with @mixins). Not supported by
JSDuck. Every class is standalone anyway. Where needed marked
them @class + @abstract instead.

ve.Range
* Rewrote truncate so that it works as expected, truncation should always reduce the length using the start/end values, not the from/to values
ve.ui.Inspector
* Added a comment about where the name argument to onBeforeInspectorOpen comes from, since it's a little bit confusing on first read (and I wrote it!)
* Calling onInitialize, onOpen and onClose methods directly, since we need to control the before or after-ness of listeners getting in there and doing their stuff - plus it's more direct
* Removed onRemove stub, which is never actually called
* Added before/after versions of initialize, open and close events
* Got rid of recursion guard since we don't need it anymore thanks to changes made in ve.dm.Surface (see below)
ve.ui.Context
* Updated event names to deal with new before/after naming of initialize, open and close events
* Removed fade-in logic since fading in doesn't even work anymore - since now we now annotate first, then open the inspector, the menu will actually exist and be open when we open the inspector even though you don't see it because it's quickly obscured
ve.ui.LinkInspector
* Made fragments non-auto selecting, in the case of onInitialize we actually call select(), which is silly since we were using an auto-selecting fragment - it's clear that this was a mistake
ve.dm.Surface
* Moved locking (polling stop and start) to the far outside edges of the change method
* I need a lot of eyes and testing on this change, it seems OK to me, but I'm suspicious that it may have side effects
* What was happening is that selection changes were being applied and then the poll was picking them up, and then the selection was coming in again as a change, but it wasn't a change at all, it was just feedback - this change event was then closing the inspector the instant it was opened - the odd part was that this only occurred when you selected backwards, which seems to be caused by the range being normalized, so it looked like a new selection even though it wasn't
ve.dm.Document
* trimOuterSpace from Range didn't consider annotated spaces to be spaces, by using the [0] trick (first character of a plain text character string or first element in an annotated character's array both are the character's value - but elements don't have a property named '0' so it skips those safely as well) we can always get the right value for comparison

The fix for bug 40339 supposedly modified when we emit contextChange events so that when the node changed, even if the context was the same, we consider it a context change (such as changing the heading level).
Unfortunately I was mentally absent when I wrote the patch and all it actually does it emit more select events.
Basically cb4877b0d0 - which does indeed fix the bug - doesn't do what it's commit message describes, but this fixes it.

Detecting contextChange events was making assumptions about the previous state, and causing a mess of problems.
Solution: detect contextChange events in a smarter way.
We also now emit contextChange event when moving to a different node. This helps fix other issues because it's possible for the selection to be the same, but the node at that range to change, and that's a context change for sure. Example would be changing the heading level.
Change-Id: I99d6fa94fae76aa940077abc9b5beacd38eb7b0b
The contextChange event is fired when:
* Changes to insertion annotations
* Changes to which nodes are selected (start/end nodes have changed)
* Attributes have changed on any element (it's probably more expensive to detect if the changes are relevant than to just emit the event and let listeners do their thing)
This fixes most of the strange behavior with the toolbar not updating properly.

ve.dm.SurfaceFragment
* Removed flawed implementation of word mode for expandRange method and made use of new getNearestWordBoundary method in the document model
ve.dm.Surface
* Got rid of useInsertionAnnotations, which allowed disabling and enabling of insertion annotations - this isn't needed anymore because it was just a dirty hack around the improper starting and stopping of surface observer that's now solved more elegantly by emitting lock and unlock before committing or rolling back transactions

Exception was caused by passing -1 to getAnnotationsFromOffset(). So
check for -1 before passing it in; getNearestContentOffset() can
legitimately return -1 if there are no content offsets in the document,
which occurs when the document is empty.
I was originally going to change getNearestContentOffset(start - 1, -1)
to getRelativeContentOffset(start, -1), but Inez correctly pointed out
that that would have unwanted results when near an inline node.
