Title: Memcached based session handler, with configurable variables in HDF

Session {
Handler = files | memcache
Path = /tmp | tcp://address:port;tcp://address2:port2;
HashBitsPerCharacter = 4|5|6
}

Note: the memcache path should start with "tcp://" and contains an address and a port.
I had no time to implement the correct parser for this setting string as in the php.ini.
