e1ff51c045 Do not use pickle for serialization in memcache, but JSON 
We don't want to use pickle as it can execute arbitrary code. JSON is
safer. However, note that it supports serialization for only some
specific subset of object types; this should be enough for what we need,
though.
To avoid issues on upgrades (unability to read pickled values, and cache
poisoning for old servers not understanding JSON), we add a
memcache_serialization_support configuration option, with the following
values:
 0 = older, insecure pickle serialization
 1 = json serialization but pickles can still be read (still insecure)
 2 = json serialization only (secure and the default)
To avoid an instant full cache flush, existing installations should
upgrade with 0, then set to 1 and reload, then after some time (24
hours) set to 2 and reload. Support for 0 and 1 will be removed in
future versions.
Part of bug 1006414.
