drbd: Remove headers from on-the-wire data structures (struct p_*)
...
Prepare the introduction of the protocol 100 headers. The actual protocol
header is removed for the packet declarations. I.e. allow us to use the
packets with different headers.

drbd: Replace and remove old primitives
...
Centralize sock->mutex locking and unlocking in [drbd|conn]_prepare_command()
and [drbd|conn]_send_comman().
Therefore all *_send_* functions are touched to use these primitives instead
of drbd_get_data_sock()/drbd_put_data_sock() and former helper functions.
That change makes the *_send_* functions more standardized.

drbd: preparation commit, pass drbd_interval to drbd_al_begin/complete_io
...
We want to avoid bio_split for bios crossing activity log boundaries.
So we may need to activate two activity log extents "atomically".
drbd_al_begin_io() needs to know more than just the start sector.
