phpdbg is a gdb-style debugger for PHP that is run from the command
line. However, it has a different PHP_SAPI value, so it was impossible
to run maintenance scripts with it (until now).
To avoid having to check both PHP_SAPI values in a bunch of places,
introduce wfIsCLI() to easily check whether running from the
command-line or not.
We're (CI team) interested in generating code coverage with phpdbg
instead of xdebug, hence this patch.

Change-Id: Id1f994ca146d7858cd8bb6ab6cdbb7718ff524fb
Avoids "Argument 1 passed to Profiler::scopedProfileOut() must
be an instance of ScopedCallback, SectionProfileCallback given"

This uses a non-standard output and requires a custom
collector that wmf does not maintain nor use anymore.

* Added doPreOutputCommit() and doPostOutputShutdown(),
which most entry points just using the later
* Also fixed problem where text profiling did not show up
* Avoid calling triggerJobs() in the file streaming
entry points

Instead of maintaining a mapping of short names to class names ('db' =>
'ProfilerOutputDb', etc.), let us adopt the convention of using the full
class name to indicate the output type. We can maintain backward-compatibility
by using simple string manipulation to transform short names to the full class
names.

* 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.

* This can happen well over 10k times per request due to the message
hooks. Avoiding the object construction seems prudent.

We've already broken profiling completely in this release. Make
this abundantly clear in the RELEASE-NOTES and just remove the
awful back-compat attempt from I2af28cd3 and I49c0a83e.

* Made use of it in the DatabaseBase classes
* For the xhprof class, this only works in HHVM for now
Change-Id: I95d7cc128d4a770328fbdd2b546972d3fc2e2e8a
* Added a standard getFunctionStats() method for Profilers to return
per function data as maps. This is not toolbar specific like getRawData().
* Cleaned up the interface of SectionProfiler::getFunctionStats() a bit.
* Removed unused cpu_sq, real_sq fields from profiler UDP output.
* Moved getTime/getInitialTime to ProfilerStandard.

Creates absurd dependency on the profiler from the parser. This profiling
is also not compatible with function-level profiling that we're trying to
aim for with xhprof.

Add a helper class to assist in collecting profiling information using
XHProf <https://github.com/phacility/xhprof> and a Profiler
implementation to hook it into the existing MediaWiki profiling system.
The Profiler includes support for generating tabular reports similar to
the traditional output of ProfilerSimpleText and ProfilerSimpleTrace or
sending data to a udpprofile daemon as supported by ProfilerSimpleUDP.
It also produces data compatible with the debugging toolbar.

This is a weird construction that only existed for dumpHTML.
DumpHTML will no longer require this as of Ia38aa904.
It won't work with future plans to separate profiling & profiling
output

- Put Profiler, ProfileSection and TransactionProfiler in their own
files and rely on Autoloader to use them (maintenance has been
using the autoloader here for some time--we don't profile the
autoloader manually)
- This reduces overhead in WebStart/doMaintenance by only loading
three functions at profiler initialization and defers until the
first profiling call happens
- Inline callback functions in ProfilerSimpleText rather than having
public static functions.
- Small comment and code formatting changes in various touched files.

As of <https://github.com/facebook/hhvm/commit/0f98cab>, it is possible to
call getrusage( [ int $who = 0 ] ) with $who = 2 to request resource usage
info for the current thread (RUSAGE_THERAD), rather than the calling process
(RUSAGE_SELF). (Earlier versions of HHVM return RUSAGE_SELF data unless $who
is 1.)
PHP5 code can assume that each request is handled in a dedicated subprocess,
but the same is not true of HHVM, which is multi-threaded. Therefore, to get
resource usage data for the current request context, it is necessary to ask
for RUSAGE_THREAD rather than RUSAGE_SELF.
To do this, introduce a new global function in Profiler.php: wfGetRusage().
It is defined there and not in GlobalFunctions.php so that it can be used early
in WebStart.php.

- Added missing types
- Fixed spacing inside docs

- Added space after switch/if/foreach
- changed else if to elseif

* Replaced use of spl hash with random transaction IDs.
These can be correlated better and make the DBPerformance
log easier to make sense of. They are also shorter.
