ccbef85dd0 Remove mutex asserion from g_gate_find(). We don't want g_gate_list_mtx 
mutex to be held here, because we want speed here.

f906581296 Remove TDP_GEOM flag from thread after ggate device creation. 
This flag means "wait for all pending requests before returning to userland".
There are pending events for sure, because we just created new provider and
other classes want to taste it, but we cannot answer on I/O requests until
we're here.

e35d3a7828 - Remove g_gate_hold()/g_gate_release() from start/done paths. It saves 
4 mutex operations per I/O requests.
- Use only one mutex to protect both (incoming and outgoing) queue.
  As MUTEX_PROFILING(9) shows, there is no big contention for this lock.
- Protect sc_queue_count with queue mutex, instead of doing atomic
  operations on it.
- Remove DROP_GIANT()/PICKUP_GIANT() - ggate is marked as MPSAFE and no
  Giant there.

662a4e5878 - Use bioq_insert_tail()/bioq_insert_head() instead of bioq_disksort().

3e019deaed Do a pass over all modules in the kernel and make them return EOPNOTSUPP 
for unknown events.

A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".

55336b83e0 Introduce a hack that will make geom_gate to work with read-only mounts. 
Now, when trying to mount file system in read-only mode it tries to
opened a device for writting to be able to update to read-write mode
latter. Ehh.

0d785336d1 Make it compile on 64-bit architectures. 
The biggest issue was that 16-bit atomic operations aren't supported
on all architectures.
