70547f3fa3 objectcache: add mcrouter support to WANObjectCache
* Update documentation about relay methods.
* Change interim key set() to add() to avoid broadcasting it.
* Remove the behavior of doing purges synchronously in the
  local DC first before relay. In both the event relayer and
  mcrouter case, they will be asynchronous. It was hardly
  even possible to use such behavior since loads come from
  slave DBs, which do not see changes right after COMMIT.

4a8ae0a0b4 Use callable type-hint in a few places
Mostly places which immediately had a:
 if ( !is_callable( $callback ) ) {
  throw new Exception(...);
 }
check at the beginning of the function.

5c8ef13306 Add WRITE_SYNC flag to BagOStuff::set()/merge()
* This blocks on writing to all replicas
  and returns false if any failed.
* This is useful if ChronologyProtector is to work across
  domains by having the writes go everywhere so that later
  reads will see them (and be local at the same time).
* Redundant doc comments were also removed.

1fa1235d32 Clean up BagOStuff::get() interface
* Callers of get() no longer have to contend with
  the annoying $casToken parameter, which is there
  but totally unusable to non-BagOStuff code.
* The default get() now delegates to doGet(),
  which callers must implement instead. They can
  ignore the overhead of generating $casToken if
  they do not implement cas(), which applies to
  callers that use the stock merge(). If cas() is
  used for merge(), then getWithToken() must be
  implemented.
* Also add BagOStuff::READ_LATEST to mergeViaCas()
  for sanity, as that missing before.
  Likewise with mergeViaLock().

1e3888de00 Start moving objectcache into libs/
The base BagOStuff class and some of the implementations are
not dependent on MediaWiki and can be in the libs folder.
