Subramanya Sastry d5c4583649 ParsoidExtensionAPI: Cleanup the toHTML / innerHTML mess
This is cleaner and less prone to subtle errors since it forces
extension developers to explicitly choose the more performant version.

Subramanya Sastry 04e9292576 Provide utility classes for extensions
* Added DOMDataUtils, WTUtils, and Util for use by extension
  developers. These classes might acquire more functionality in the
  future based on usage and need.

* Added PHPUtils for a single helper to work around a GC bug in PHP.
  Once we move on to a newer version of PHP where this is fixed, we
  can get rid of this class and helper.

* These classes proxy the various helpers used by currently ported
  extensions. For reasons of coherency, the set of helpers in these
  classes are a superset of what the extensions use.

* Updated references to the other helpers to use these classes

* Since DOMUtils or DOMCompat are not Parsoid-centric, it feels safe
  to provide extensions direct access to those utils classes. We could
  consider moving DOMUtils to the Core/Utils namespace if appropriate.

* In one case, I replaced the escapeNowikiTags helper that the Nowiki
  "extension" used with an inlined preg_replace.

* TODO: Add unit tests to ensure these utils don't break!

Subramanya Sastry 98da9ba908 Extensions: Remove inPHPBlock wt2html pipeline option
* The functionality looks effectively identical to inlineContext
  and everywhere inPHPBlock was inspected, inlineContext was also
  being inspected.

* Cite's use of this flag is a hack to get desired bacward compatible
  behavior but that is a hack no matter what we call the flag.

Subramanya Sastry 0cc3ca1b98 Move DomSourceRange to Core; ParsoidExtensionApi to Ext
* At this point, DSR is a first-class Parsoid concept and
  extensions will need to use this as well. So, make it part
  of the Core/ namespace to capture high-level concepts that
  might be used outside Parsoid itself.

* Move ParsoidExtensionApi to the Ext directory since that is
  where it best belongs.

* html2wtPreProcessor is currently unimplemented but there is WIP
  code in Parsoid/JS that can be revived at a later point. No need

* In both cases, pass $extApi so they can access any necessary

Subramanya Sastry d0a9c42c98 Cite: Remove more Parsoid internals knowledge
* Remove use of $env from ReferencesData and RefGroup by
  providing high-level helpers in ParsoidExtensionAPI.

  - Given a fragment id, provide helpers to fetch fragment DOM
    or fragment HTML
  - Fetch the URI for the current page (being parsed)

* There is still a lot of subtle knowledge Cite has about
  how data-parsoid and data-mw attributes are held off to the
  side in a bag and all the pp* and load/store manipulation
  of those attributes. It would be an interesting exercise
  to purge this implementation of those notions OR figure out
  high-level concepts that we document as being part of Parsoid
  reality that we'll forever support.

Subramanya Sastry 5e256b48aa Start untangling Parsoid internals from extensions
* In this patch, toDOM, fromDOM, and DOM postprocessor extension
  methods all get a ParsoidExtensionAPI object. These API objects
  are constructed at the appropriate times in the wt2html and html2wt
  pipelines.

* Got rid of direct references to SerializerState from fromDOM
  methods in extensions.

* Exposed generic serialization and wikitext escaping methods
  in ParsoidExtensionAPI for extensions to leverage. The implementation
  of these methods is partial and only supports current usage
  of extensions in Parsoid's repo. This will need to be fully
  fleshed out going forward.

* Stopped exposing wt2html options in toto and provided more specific
  convenience methods.

* Reduced direct access to the Env object in a few more places.

* Cite has code to inspect embedded HTML in data attributes of a node.
  Moved this code out of Cite into ParsoidExtensionAPI which reduces
  knowledge that extensions need. Unlike the other cleanups, this one
  is more of a convenience method since this code only requires
  knowledge of a publicly published spec. But, nevertheless an useful
  cleanup since it simplifies Cite's complexity just a bit.

* More followup work is needed.
  - before/after methods should be eliminated in favour of a config flag
    that implements the inline/block layout option. Once this is done,
    extensions will no longer need direct access to the SerializerState
    internal object.
  - Env exposure should be reduced.
  - Provide access to Sanitizer via ParsoidExtensionAPI instead of
    needing extensions to directly import it.
  - It should be possible to eliminate the need for extensions to know
    about DSR / DSR-shifting and do it automatically via some high-level
    conceptual flag.
  - It might also be possible to infer source offsets directly via args
    instead of passing that explicitly.
  - Should we provide a convenience helper class with access to all the
    src/Utils/* methods?

Subramanya Sastry ad229c1ac0 One more fix for T235656
It is about time to implement a generic fix for T214994 which will
capture the Cite-specific scenario we are tackling here in bits
and pieces. We have fragments of a T214994 solution spread in
Utils/ and here while tackling shiftDSR and convertOffsets
for Parsoid/PHP. So, someone needs to take a look at all these
pieces and implement the necessary abstraction.

As part of that, maybe we also need to revisit our embedded HTML
data-* representation so there is a uniform way to inspect these
attributes rather than every semantic element (template, extensions,
lang variants, media) choosing their own custom embedding scheme
which makes discoverability harder and error-prone.

Subramanya Sastry 2be3ab72c6 References.php: Use strlen not mb_strlen to count page length
* When a page is missing an explicit <references /> tag, we insert
  an implicit <references /> tag and assign it a zero-width DSR with
  a starting offset equal to the length of the page. However, now that
  we have byte offsets, that should have been strlen, not mb_strlen.

  This was causing incorrect DSR assignment on this implicit tag
  and causing trailing newline selser diffs on these pages.

* Debugged on this reduced test case: "* a – b <ref>x</ref>\n\nc\n\n"
  and comparing selser trace and then DSR offsets on the DOMs.

Tim Starling has indicated in couple different places that end(..)
is not preferred and he had implemented a private version of lastItem
in the PEG grammar code whereas PHPUtils::lastItem was recommending
use of end(..).

In this patch, I moved the implementation from the grammar to PHPUtils
and replaced end(..) with PHPUtils::lastItem in a number of places in
the codebase. We should discuss whether we want to use this helper
everywhere.

Resolved a couple of PORT-FIXMEs in the bargain.

Restructure ExtensionTag as an abstract class with default do-nothing

The intention is to move SerialHandler::fromHTML and SerialHandler::before
into this framework as well.  Every "optional" method should have a default
implementation in the base class which returns false.

Subramanya Sastry 720f1db084 Fix exception handling: Don't catch exceptions and suppress them
* Now that we are in sync land, we don't need to catch exceptions
  and log error messages at multiple places. Let them bubble up
  to the top.

* I noticed this was actually getting in the way of debugging because
  with $env->log unimplemented, I was only getting very generic
  failures instead of the root cause that was being suppressed
  and unlogged.

* There are still a couple of places where we have generic Exception
  catching in place where it does make sense currently. For example,
  we aren't interested in what caused a templatedata fetch to fail.
  We simply fall back to regular serialization - the rationale here is
  that it is better to emit a transclusion without the preferred formatting
  (but syntactically correct) instead of losing the edit altogether.

* Minor unrelated fix in Cite/Ref.php: Use !isset() instead of empty()

Pavel Astakhov 005176a355 Port Cite extension
* All wt2wt, html2wt, and all but one html2html tests pass in
  hybrid mode when entire html2wt code is run in PHP

  Set "Serializer: true" in the html2wt section of phpconfig.yaml

* The single failing html2html test is a <gallery> test which is
  presumably related to the unported <gallery> extension code, but
  not sure. Not investigating it now.

* Update Parsoid Extension API to provide access to extension source
  without exposing internals.
