This class handles caching across distance sites where purges
must reach both. It also aims to make purging more reliable in
the face of network glitches and node consistent hash ejection.

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.

* Set a custom profiler with no expectations to avoid tripping
the "0 write" expection. This avoids useless log entries.

The base BagOStuff class and some of the implementations are
not dependent on MediaWiki and can be in the libs folder.

* merge() using the locking version by default. The callers that implement cas()
override merge() to use the cas-based version. Those that do not no longer
need to define the unused dummy method.
* Removed some redundant doc blocks.

ObjectCache::newFromParams() will handle a 'loggroup' parameter
specially, getting an instance of \Psr\Log\LoggerInterface to
pass to the BagsOStuff.
BagOStuff implementations can use $this->logger which will be
an implementation of \Psr\Log\LoggerInterface. As this is set in
BagOStuff::__construct(), all subclasses must now call the
parent constructor.
The goal of this is to make the logging in BagOStuff non-MediaWiki
specific, in the hopes of separating it out into a separate library
in the future.

Xhprof generates this data now. Custom profiling of various
sub-function units are kept.
Calls to profiler represented about 3% of page execution
time on Special:BlankPage (1.5% in/out); after this change
it's down to about 0.98% of page execution time.

Partial deletion percentage progess was computed using
$remainingSeconds. This is incorrect since $remainingSeconds
is going to *decrease* ( instead of increase ) while the
process continues.
The correct implementation uses 'processed seconds' instead.

Avoid an unnecessary serialize() call on get() requests, which makes it
faster and also happens to work around a nasty crash bug which is
causing lots of segfaults right now.
CAS semantics should be the same, if the caller handles a CAS token in
an opaque way and does not assume it is a string. I could only find one
caller of cas() in core and WMF deployed extensions, and that is
BagOStuff::mergeViaCas(), which does correctly handle CAS tokens of any
type.

- Added space after reserved words: function, foreach, if
- Combined 'else if' into elseif
- Added braces to one-line statements
- Added spaces after comma, before parentheses

Fixes "Fatal error: Argument 4 passed to Memcached::cas() must be an
instance of int, float given".
