request back from the receive queue -- it might already be processed
by remote_recv_thread, which lead to crashes like below:
(primary) Unable to receive reply header: Connection reset by peer.
(primary) Unable to send request (Connection reset by peer):
WRITE(954662912, 131072).
(primary) Disconnected from kopusha:7772.

Taking the request back was not necessary (it would properly be
processed by the remote_recv_thread) and only complicated things.

indication when a request can be moved to done queue, but also for
detecting the current state of memsync request.
This approach has problems, e.g. leaking a request if memsynk ack from
the secondary failed, or racy usage of write_complete, which should be
called only once per write request, but for memsync can be entered by
local_send_thread and ggate_send_thread simultaneously.
So the following approach is implemented instead:
1) Use hio_countdown only for counting components we waiting to
complete, i.e. initially it is always 2 for any replication mode.
2) To distinguish between "memsync ack" and "memsync fin" responses
from the secondary, add and use hio_memsyncacked field.
3) write_complete() in component threads is called only before
releasing hio_countdown (i.e. before the hio may be returned to the
done queue).
4) Add and use hio_writecount refcounter to detect when
write_complete() can be called in memsync case.

only being able to create 1TB partitions:
o) Use an unsigned 32-bit quantity to store the number of disk sectors.
o) Detect overflow of said 32-bit quantity and clamp to 2^32.
o) Rather than returning the disk sector count from get_params, return 0 on
success, since its return value is only ever compared to -1 to detect
failure. This would cause returning 2^32 sectors to be interpreted as an
error.

Currently, we've got a problem that interface isn't IFF_UP at the time
we assign it a redundant address, and the latter gets stuck in INIT state.
Additional SIOCSIFFLAGS from ifconfig(8) kicks it to a working state.
A proper fix is kernel side and appeared to be non-trivial, not to be
checked in before 10.0-RELEASE.
