Philipp Reisner dad2055481 drbd: Removed drbd_state_lock() and drbd_state_unlock()
The lock they constructed is only taken when the state_mutex
was already taken. It is superficial.

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.
