This is being backported because many users copy lua modules from
Wikipedia, and thus benefit from forwards-compatibility.
For the most part, it is a good idea to avoid global variables and use
`local` variables instead. Quoting from the ScopeTutorial[1], "The
general rule is to always use local variables, unless it's necessary for
every part of your program to be able to access the variable (which is
very rare)."
Wikimedia module authors have written "Module:No globals", which errors
on the use of any global variable. On the English Wikipedia, this is
used on 32% of pages (18 million). Wikidata[2] indicates that it's been
copied to 334 other wikis.
Lua itself distributes an extra named "strict.lua"[3], which is what
this is based off of. Similar to bit32.lua, this is a pure-Lua library
that can be imported/enabled with `require( "strict" )` at the top of a
module.
The two changes I made from Lua's strict is to exempt the `arg` key,
which is used internally by Scribunto, and remove `what()`, since we
don't enable access to `debug.getinfo()` for security reasons.

This means that these tests are only run for test runs on this repo,
and will not be run when this repo is included in CI as a dependency
of any other repos, or the Wikimedia-wide gate. Any changes to other
repos are implicitly assumed to be unable to break these tests.

Also remove Scribunto_LuaError::setLineMap(), which has apparently never
been used since it was added in Ia51f439e.

This is getting close to the point of "don't do that, just wrap the
built-in". But since it's a regression in a recent patch, let's restore
the old behavior here.

When an #invoke is passed as an argument to another #invoke,
mw.getCurrentFrame() at module scope will return the wrong frame.
On the PHP side, we need to always reset the frame when processing
an #invoke, not just when there's no frame already. I don't remember why
I82dde43e wasn't done that way, but changing it doesn't make any tests
fail and Scribunto tends to have good tests.
On the Lua side, we need to do the same. The logic wih mw.getCurrentFrame()
using a global that gets stored, modified, and reset in several places
was getting confusing, so this patch reworks the logic to inject a
globalless mw.getCurrentFrame() into each #invoke's cloned environment
instead.

The test currently runs a busy loop that does string operations 1
billion times, when really it just needs something that takes more than
2 seconds of CPU time. On the other hand, there's another test that uses
the same method to run only 100 string operations for a different test.
Add a second parameter to have it exit early if enough CPU time has been
used, and use it in the first test.

RFC 3986 allows IPv6 literals (and future IP versions) by having the
"host" enclosed in brackets, like `http://[2001:db8::]`. mw.uri should
handle these appropriately.

If TemplateStyles installed, then enable it in the Module namespace
by default. This change is analogous to I96d9601ff80c2d3eb052c01.
Since both extensions use the ContentHandlerDefaultModelFor hook, Scribunto
will check if the sanitized-css model has already been set, and if so, not
override it. If the page is in NS_MODULE, it will set the content model to
Scribunto, but allow further hooks to override it, in which case it is
expected that TemplateStyles would set it to sanitized-css.

It's easily possible for Lua to raise errors where the string is not
valid UTF-8. When we turn that into a Scribunto_LuaError, we should
normalize it so other things don't break.

As documented, string.gub( 'foo', '%a', '%1' ) should raise an invalid
capture index error because there is no capture with index 1 in the
pattern. But in fact it treats %1 as %0 in this situation. The ustring
library should match this behavior.
This patch also adds some tests for the behavior of gsub with table and
function replacements when the pattern does have captures.

Change-Id: Ie3e6c2eafa4a05989815c62c7037167642581751
If the replacement table or function results in a value that isn't a
string or number (or nil), string.gsub raises an error. Have ustring
raise the same error.
