* Use OutputPage::output() as the method to mask latency, since it
takes a good while to run. By the time it runs, cache replication
should have caught up, so the reap call will likely not block.
* For redirects emitted after changes in POST, instead of masking
with OutputPage, add a parameter to the redirect and block on
the positions appearing. This uses the redirection RTT to mask
the replication latency.

* 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.

Especially useful when interacting with getWithSetCallback of
HashBagOStuff where a $exptime is required before the callback.
In set() it is typically left out and thus not as counter-intuitive.

Also consistently use self:: instead of BagOStuff:: for constants
referenced within the BagOStuff class.
