to allow other code (eg. the SyncML code from Horde) to open the eGW session, we use a first memcache key identical to the original memcache session handler (for the first junk/1MB)

* Fixes a problem of the buildin session handler of the memcache pecl extension,
* which can NOT work with sessions > 1MB. This handler splits the session-data
* in 1MB junk, so memcache can handle them.
* in 1MB junk, so memcache can handle them. For the first junk we use an identical
* key (just the session-id) as the original memcache session handler. For the further
* junks we add -2, -3, ... so other code (eg. the SyncML code from Horde) can
* open the session, if it's size is < 1MB.

* To enable it, you need to set session.save_handler to 'memcache' and
* session.save_path to 'tcp://host:port[,tcp://host2:port,...]',
