Move the MWLogger PSR-3 logging related classes into the
MediaWiki\Logger namespace. Create shim classes to ease migration of
existing MWLoggerFactory usage to the namespaced classes.

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.

This was used in 2 special classes, the logger classes and spread
to a few other random classes.
Afaik this has no meaning. Is for something we don't use, and
goes against the meaning of '@section' in Doxygen, which we do
use.
In Doxygen output, all LICENSE references became links to
ProfilerXhprof (the one Doxygen encoutered first).

The MWLogger class is actually a thin wrapper around any PSR-3
LoggerInterface implementation. Named MWLogger instances can be obtained
from the MWLogger::getInstance() static method. MWLogger expects a class
implementing the MWLoggerSpi interface to act as a factory for new
MWLogger instances. A concrete MWLoggerSpi implementation using the
Monolog library is also provided.
New classes introduced:
; MWLogger
: PSR-3 compatible logger that wraps any \Psr\Log\LoggerInterface
implementation
; MWLoggerSpi
: Service provider interface for MWLogger factories
; MWLoggerNullSpi
: MWLoggerSpi for creating instances that discard all log events
; MWLoggerMonologSpi
: MWLoggerSpi for creating instances backed by the monolog logging library
; MWLoggerMonologHandler
: Monolog handler that replicates the udp2log and file logging
functionality of wfErrorLog()
; MWLoggerMonologProcessor
: Monolog log processer that adds host:wfHostname() and wiki:wfWikiID()
to all records
New globals introduced:
; $wgMWLoggerDefaultSpi
: Default service provider interface to use with MWLogger
; $wgMWLoggerMonologSpiConfig
: Configuration for MWLoggerMonologSpi describing how to configure the
Monolog logger instances.
This change relies on the Composer managed Psr\Log and Monolog libraries
introduced in Ie667944.
