Yet another 0.7 release...

0.7.20 (api:79/proto:74)
 * The GC comparison code failed to start a resync in case the two
   cluster node failed simultaneously (common power failure).
 * Fixed DRBD's code to start kernel threads to work on 2.6.17 also.
 * IOCTL return codes fixed for 32bit userland - 64 bit kernel
 * New config option "unplug-watermark".
 * Released the drbd_alloc_ee() / drbd_free_ee() implementation from 
   the DRBD+ branch to the main branch.

In case you use a non default AL size, and both nodes of your
cluster crash simultaneously, DRBD failed to start the resync
of the AL covered areas.

This should alert all users that tuned their al-size, and cause
them to upgrade to 0.7.20.

The "unplug-watermark" is usefull to tune performance for
disk controllers with huge request queues.
