wfSuppressWarnings() and wfRestoreWarnings() were split out into a
separate library. All usages in core were replaced with the new
functions, and the wf* global functions are marked as deprecated.
Additionally, some uses of @ were replaced due to composer's autoloader
being loaded even earlier.
Ie1234f8c12693408de9b94bf6f84480a90bd4f8e adds the library to
mediawiki/vendor.

A user just logged on to the #mediawiki channel to ask for help because his
webhost disallowed php_uname(), causing wfIsWindows() to crash. Google
autocompletes 'php_uname()' to 'php_uname() has been disabled for security
reasons', so it is probably not uncommon. Consulting the PHP_OS constant
instead side-steps the problem nicely.

* Associate Profiler objects with a request context by adding a $context
property with a getter and a setter.
* Introduce ProfilerOutputStats, which writes profiling data to the stats
buffer associated with the current request context.
* Make it the Profiler class's responsibility to enforce $wgProfilerLimit.
* Deprecate $wgProfilerLimit in favor of the (more aptly named, IMO)
$wgProfiler['threshold'] config setting.
* Tidy up Profiler instance creation code in Profiler::instance().
* Add Profiler::getOutputs, which returns an array of ProfilerOutput instances
which are configured for the current profiler and whose canUse() method
returns true.
* Make ProfilerStub not log by creating a stub ProfilerStub::logData() method
which does not call the parent. Previously the parent class checked if $this
was an instance of ProfilerStub and returned early if so.

* Deprecate $wgRequestTime in favor of $_SERVER['REQUEST_TIME_FLOAT'], which is
more accurate. Because $_SERVER['REQUEST_TIME_FLOAT'] is only set for PHP
5.4+, set it to microtime( true ) in WebStart.php for back-compatibility.
* Add a 'requestTime' property to WebRequest objects, set to
$_SERVER['REQUEST_TIME_FLOAT'] for WebRequest or the instance creation time
for FauxRequest instances.
* Use that to provide WebRequest::getElapsedTime(), which gets the time since
the request was initiated.
* In wfLogProfilingData(), get the user and request objects from the context
object rather than from global scope.
Opportunistic clean-up: move the magic quotes check to WebStart.php and make
the error message more helpful.

Right now wfLoadExtension() and related functions explicitly load
extensions immediately, bypassing the queue. This was done to be
extremely backwards-compatible with the old require_once style of
loading which does the same.
However, for a future configuration database to work, we need to be able
to reliably load extensions after configuration (LocalSettings.php) is
loaded, which is currently at the top of Setup.php. Rather than doing
this later, we should do this now to make sure the registration system
will be able to handle it.
In Wikimedia production, excentions are currently being loaded with
direct calls to:
ExtensionRegistry::getInstance()->queue(...);
so we know that this should work, but that is not a nice API for sysadmins
and developers to be entering into LocalSettings.php.
If for some reason an extension really needs to be loaded immediately,
they can still call:
ExtensionRegistry::getInstance()->loadFromQueue();
But that should be the exception, not the norm.

This function is backwards:
* The stated purpose is to generate a list of differences for callers to parse,
however we already have DiffEngine that returns a list of differences that you
don't need to parse manually shooting your feet off in process.
* With improvements in PHP performance in the last 10 years, shelling out instead of using
a pure-PHP diff has a doubtful performance benefit.
* Even in configurations where it's faster on predominant diffs (which have to be huge),
shelling out has its own security implications.
This function is not used in core. The only extensons using it are Echo (which just parses
its output so would be better off with DiffEngine) and AbuseFilter, let's not add more users
by tolerating this function.
Also, add error checking while I'm at it.

This patch adds a metric data service object to the IContextSource interface,
with full support for StatsD meters, gauges, counters and timing metrics, via
the liuggio/statsd-php-client, which this patch also introduces.
Usage example:
$stats = $context->getStats();
$stats->increment( 'resourceloader.cache.hits' );
$stats->timing( 'resourceloader.cache.rtt', $rtt );
The metrics are flushed to a StatsD server, which may be specified via the
'StatsdServer' configuration key. If no such configuration key exists, the
metrics are discarded.
The StatsD client supplants MediaWiki's StatCounter class. wfIncrStats()
will continue to work, but it will delegate to the StatsD data object.

wfEscapeShellArg() can handle multiple params, escaping each.
This patch changes wfShellExec() to call wfEscapeShellArg() directly
instead of doing the gluing itself.
This patch also extends wfEscapeShellArg() to accept an array parameter
optionally instead of as separate args, which is often useful.
Added also unit test cases for single, multiple args, and single array args.

Time wounds all heels. During the code review for the PSR-3 logging
introduction, several people asked me why we needed a wrapper
for Psr\Log\LoggerInterface if the point was to use the standard. At the
time I was convinced that it would be better to introduce the dependency
via a wrapper class so that we could use the wrapper to patch over any
deficiencies that we might find in the PSR-3 API. After going on to work
on a project to disentangle other MediaWiki components from internal
project dependencies I have suddenly and clearly seen the error of my
ways.
We still need a logger factory as PSR-3 does not specify
a standard mechanism for creating Psr\Log\LoggerInterface instances. My
solution is to convert MWLogger into MWLoggerFactory to retain a static
factory interface for creating PSR-3 loggers but remove the MWLogger
wrapper class itself in favor of direct exposure of
Psr\Log\LoggerInterface to the MediaWiki consumer classes.

For example, if the database cannot be connected to, the language is
something other than 'en', and the l10n cache is LCStoreDB, then the
call to Language::factory() in Setup.php line 604 will do it when it's
trying to get the fallback list.

Introduces wfLoadExtension()/wfLoadSkin() which should be used in
LocalSettings.php rather than require-ing a PHP entry point.
Extensions and skins would add "extension.json" or "skin.json" files
in their root, which contains all the information typically
present in PHP entry point files (classes to autoload, special pages,
API modules, etc.) A full schema can be found at
docs/extension.schema.json, and a script to validate these to the
schema is provided. An additional script is provided to convert
typical PHP entry point files into their JSON equivalents.
The basic flow of loading an extension goes like:
* Get the ExtensionRegistry singleton instance
* ExtensionRegistry takes a filename, reads the file or tries
to get the parsed JSON from APC if possible.
* The JSON is run through a Processor instance,
which registers things with the appropriate
global settings.
* The output of the processor is cached in APC if possible.
* The extension/skin is marked as loaded in the
ExtensionRegistry and a callback function is executed
if one was specified.
For ideal performance, a batch loading method is also provided:
* The absolute path name to the JSON file is queued
in the ExtensionRegistry instance.
* When loadFromQueue() is called, it constructs a hash
unique to the members of the current queue, and sees
if the queue has been cached in APC. If not, it processes
each file individually, and combines the result of each
Processor into one giant array, which is cached in APC.
* The giant array then sets various global settings,
defines constants, and calls callbacks.
To invalidate the cached processed info, by default the mtime
of each JSON file is checked. However that can be slow if you
have a large number of extensions, so you can set $wgExtensionInfoMTime
to the mtime of one file, and `touch` it whenever you update
your extensions.
