This is used as the main stash by default, which is not a
performance cache but a stash for ephemeral values typically.

* Add the ability to expose key BagOStuff attributes like whether the
emulation SQL cache is being used. Several callers use hacks to detect
this and can be updated later.
* Fallback to a safe empty WAN cache in the CACHE_DB case. This fixes
a regression from f4bf52e843.
* Also add this protection to the server cache, which could break
similarly before too.
* Also fix CACHE_ANYTHING by avoid the recursion risk from
fc1d4d7960 by just checking the disabled service map.

Mostly places which immediately had a:
if ( !is_callable( $callback ) ) {
throw new Exception(...);
}
check at the beginning of the function.

* 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.

* 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().

Fixed PHP runtime warnings:
> Declaration of ReplicatedBagOStuff::getMulti() should be compatible with BagOStuff.
> Declaration of ReplicatedBagOStuff::decr() should be compatible with BagOStuff.
