To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.

This also removes and empty lines from method/function bodies at the
beginning and end.

PHPDoc (of the public API) says that this method returns string but it also returns null, which is not allowed in some method calls. This fixes that behaviour and returns an empty string and fixes all code paths that explicitly checked for null to be still compliant.

Found while enabling the strict_typing for lib/private for the PHP7+ migration.

Apparently scan leads to some issues sometimes on cluster. So just use
the get function to fetch the keys.

* allow configuration of memcache options

Use production values for memcached as explained in http://apprize.info/php/scaling/15.html

The current implementiation uses ascii based serialization. This PR should reduce traffic to the memcached server.
