Philipp Reisner 00d56944ff drbd: Generalized the work callbacks 
No longer work callbacks must operate on a mdev. From now on they
can also operate on a tconn.

Instead of keeping a separate tree for local and remote write requests
for finding requests and for conflict detection, use the same tree for
both purposes.  Introduce a flag to allow distinguishing the two
possible types of entries in this tree.

Philipp Reisner 257d0af689 drbd: Implemented receiving of new style packets on meta socket 
Now drbd communication with protocol 100 actually works.
Replaced the remaining p_header80 with p_header where we
no longer know which header it is.

In the places where p_header80 is still in use, it is on
purpose, because we know that it is an old style header
there.
