To prevent large template DOM caches from sending servers into swap,
throw an exception when more than some number of DOM elements are
parsed. Unfortunately, it wasn't possible to return a normal error
message, because it broke PST and extractSections and corrupted the
article text. It's safer to refuse to save the edit, and we don't
have decent ways to do that short of throwing an exception.
Ideally we would like to have an upstream patch that hooks libxml to
allocate memory from PHP's request pool, then a fatal error would be
raised instead of swapping.

This patch marks the regex matching url protocol as being case
insensitive. We will from now render links like [HTTP://ww].
Tests added.

* Also normalized 0 => false for the rev ID parameter in some places.
* Broke some long lines and shorted a variable name in Skin.php.

Replacing wfMsgExt() with wfMessage() in 4e1ccf0 causes an exception on
parse when the defaults are used for $current and $max. I don't know if
there are other similar fatal errors caused by that set of commits.

If PHP's PCRE is not compiled with unicode property support, this causes
the regexes used by the parser to not compile, causing the parser to
output giberish. Its been reported that the default PHP package for
cent os has PCRE in such a config.
As a result the installer will output total giberish. The user has
no idea what went wrong because there is no meaningful output.
To counter that, cause Parser to throw an exception in that case.
It seemed easier than figuring out how to convince the installer
not to parse the environment check. For completeness sake though
I fixed the PCRE environment check to adequetely check for PCRE
not having unicode support.
This should be backported to 1.19 since there are quite a few
complaints about the issue on project:Support_desk. /me has
no idea what the procedure for that is in our new git world

* Replaced WikiPage::DATA_FROM_* constants with IDBAccessObject ones.
* Renamed IDBAccessObject constants a bit for visual consistency.
* Removed AVOID_MASTER parameter and replaced calling instances with READ_NORMAL.
Instead of getting page_latest from the master and the revision from a
slave, just get it all from the master in one RTT. Most callers used
AVOID_MASTER (and now READ_NORMAL), so this case is barely hit anymore.

* Made refreshLinksJob2 always spawn smaller jobs. This can reduce
the problem of all runners doing the same refresh jobs by increasing the
granularity of the work to single pages parses per job.
* Avoid master queries when fetching the latest revision for refresh links jobs.
Also avoid the master for template fetching on parse. A LoadBalancer waitFor()
call is used instead. The main reason for hitting the master to fetch templates
was this job itself.
* Fixed bug in refreshLinksJob2 where one missing page would cause all the
remaining updates for pages to be aborted.
* Factored out some code duplication between the two refresh links job classes.

The $text is constant and that means, the length of $text is also
constant, store it in a local var is easy than.

I am not sure, but this looks wrong, because it adds the type to the
array and not the child.
This method is unused in core and wmf extensions, maybe
removing/deprecating is a better idea, but I am not sure, if that is
possible.
I have only see this possible error, while looking through the
preprocessor.

The alignment of image thumbs should follow the page content language instead of the wiki content language.
For this it needs the parser context, and because it makes sense to have it as first parameter, I renamed makeImageLink2() to makeImageLink(), the 2 seemed to be redundant anyway.
The old function name keeps the old behaviour, but can be removed quite soon since almost no extension is using it.

Add a lang parameter to DateFormatter so it can work in any language instead of only the site content language.
(The memcached key is now per language code.)
Use by default parser->getTargetLanguage() so it is parsed in the page content language by default.
Also add some documentation and remove unneeded whitespace.
If needed, a parameter to {{#dateformatter}} can now be easily added, to specify the language to format in.

When inserting XML elements inline <such as this one>, doxygen chokes
about it not being known. Simply enclosing the tag in double quotes
prevents doxygen from emitting a warning.
Also enclosed a few invalid functions calls such as \. and double quoted
the HTML entities such as &foobar;

This patch add the hook 'InternalParseBeforeSanitize' which gets called
during Parser's internalParse method just before the parser removes
unwanted/dangerous HTML tags.

In order to correctly output an error message that might contain
wikilinks, Cite.php needs a hook that is called after the page is parsed
but before the call to replaceLinkHolders().

Currently a simple Title::exists() or Title::getArticleId() call on a
non-existent title can cause the title marked as redlinks in LinkCache,
even if a title in another variant exists. A visible appearance is that
the function refuses to try other variants of a link if the link has
already been checked by {{#ifexist:}}, which internally calls
$lang->findVariantLink() then $title->exists() is invoked.
$titlesToBeConverted is also tweaked to avoid the trailing "\0".

Pre-save transform now accepts full width commas, and a parser test is added,
which passes. Originally done by Conrad Irwin, branched out by Tim in r62689
along with a bunch of other stuff, and then it sat in bugzilla for a few months.

Add $indexOffset parameter to PPFrame::newChild(). This makes it
possible to use newChild() for interpreting named parameters to
invoke in Scribunto -- otherwise I would have had to duplicate its
functionality, which would have been tricky given that I wanted to
make a real frame with an expand() method. Setting $indexOffset allows
newChild() to start counting numbered parameters from somewhere other
than the first pipe character, leaving room for the Scribunto function
name.
Fixed PPCustomFrame_*::getArguments(), was missing for no apparent
reason. I didn't end up using it in Scribunto, but there's no harm in
adding it anyway.
