Lars Ellenberg 181286ad22 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.

Andreas Gruenbacher 6038178ebe drbd: Change how the "handshake" packets are called 
Packets of type P_HAND_SHAKE define which protocol versions and features
a node supports.  For clarity, call those packets P_CONNECTION_FEATURES
instead.

(This does not determine the features that a specific drbd device
supports, such as drbd protocol A, B, C.)

Andreas Gruenbacher e5d6f33abe drbd: Change how the initial packets are called 
The first packets exchanged when a connection is established are
referred to as P_HAND_SHAKE_S and P_HAND_SHAKE_M in the code, followed
by P_HAND_SHAKE packets.  To avoid confusion between these two unrelated
things, call the initial packets P_INITIAL_DATA and P_INITIAL_META.

Lars Ellenberg f399002e68 drbd: distribute former syncer_conf settings to disk, connection, and resource level 
This commit breaks the API again.

Move per-volume former syncer options into disk_conf.
Move per-connection former syncer options into net_conf.
Renamed the remainign sync_conf to res_opts

Syncer settings have been changeable at runtime, so we need to prepare
for these settings to be runtime-changeable in their new home as well.

Introduce new configuration operations, and share the netlink attribute
between "attach" (create new disk) and "disk-opts" (change options).
Same for "connect" and "net-opts".

Some fields cannot be changed at runtime, however.
Introduce a new flag GENLA_F_INVARIANT to be able to trigger on that in
the generated validation and assignment functions.
