Enable memcache automatic compression, starting at 20k and only if compression gain...

Allows storage of larger objects (over 1mb in size uncompressed), such as huge LDAP schemas.
Should also improve cache efficiency (allows more stuff to be stored in same memory) and reduce network latency (less data transfer)

(redo commit 1e9c03e1993b5d2978ac4c5213a8a64e0150b4a2 which was apparently lost during pluginization)
