This is useful when the timestamps to be checked depend on the value or are stored
in the database rather than as check keys.

Adds MD5 hashing to the generation of keys for WinCache. This
fixes the issue of keys (e.g. sub-headings) longer than 150
characters.

Also add headings to separate docs for deployment/administration,
from docs for developers using an existing instance of it.

This can be used to discard all values before a certain point in
time, such as periods of severe network problems or misconfiguration
that resulted in missed purges.

This lets backends that support CAS take advantage of it.
Also fix race condition with merge() in asyncWrites mode where two
threads might add to a list/set but the first request finishes after
the second, which would erase an item during the set().

Interpret "1 attempt" as non-blocking and use 3 seconds otherwise
(instead of 6 seconds). This means that the WAN cache merge call
does not block.

Proxy to the "master"/"write" cache object method. This is similar to the
approach taken in MultiWriteBagOStuff

* Provide a sensible default for the HTTP timeout, and make it configurable.
* Also make HTTP proxy and caBundlePath configurable.
* Pass through the logger object to the HTTP client, as in EtcdConfig.
* Do not treat a 404 response code for DELETE or 204 for PUT as errors. The
doc comment already said that delete() should return true if the item
was not found.

This will usually let one distinguish asynchronous preemptive cache refreshes
from synchronous value recomputations due to actual cache misses.

The get() $cas_token parameter was changed into $flags, which can act
as a switch to make the return value an associative array of details.
pecl and PHP-based memcached BagOStuff class both pass all tests now.
Bug: T196125
Change-Id: I4678250331a48db4d50d1fc6c489c991a4dee920
* Provide a default lock-based BagOStuff::cas implementation
* Make RedisBagOStuff::merge() use mergeViaCas()
* Use the raw unserialized string as the redis CAS token to
avoid any bad interaction with __wakeup() methods changing
field values every time
* Make RedisBagOStuff::incr() return false when there is no
such key, not null
* Rewrite merge() test to make the order of write/cas phase
of the parent and child merge() calls well defined instead
of arbitrary usleep() calls
* Avoid cache key reuse in test runs

Find: /isset\(\s*([^()]+?)\s*\)\s*\?\s*\1\s*:\s*/
Replace with: '\1 ?? '
(Everywhere except includes/PHPVersionCheck.php)
(Then, manually fix some line length and indentation issues)
Then manually reviewed the replacements for cases where confusing
operator precedence would result in incorrect results
(fixing those in I478db046a1cc162c6767003ce45c9b56270f3372).
