- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

Extend GEOM Gate class to handle read I/O requests directly within the kernel. This will allow HAST to read directly from the local component without even communicating userland daemon.

In g_gate_create() there is a window between when g_gate_softc is registered in g_gate_units array and when its sc_provider field is filled. If during this period g_gate_units is accessed by another thread that is checking for provider name collision the crash is possible.
Fix this by adding sc_name field to struct g_gate_softc. In g_gate_create() when g_gate_softc is created but sc_provider is still not sc_name points to provider name stored in the local array.

Please welcome HAST - Highly Avalable Storage.
HAST allows to transparently store data on two physically separated machines connected over the TCP/IP network. HAST works in Primary-Secondary (Master-Backup, Master-Slave) configuration, which means that only one of the cluster nodes can be active at any given time. Only Primary node is able to handle I/O requests to HAST-managed devices. Currently HAST is limited to two cluster nodes in total.
HAST operates on block level - it provides disk-like devices in /dev/hast/ directory for use by file systems and/or applications. Working on block level makes it transparent for file systems and applications. There in no difference between using HAST-provided device and raw disk, partition, etc. All of them are just regular GEOM providers in FreeBSD.
For more information please consult hastd(8), hastctl(8) and hast.conf(5) manual pages, as well as http://wiki.FreeBSD.org/HAST.

Fix problems with destroy and forcible destroy functionality: - hold/release device in start/done routines, this will probably slow down things a bit, but previous code was racy; - only release device if g_gate_destroy() failed - if it succeeded device is dead and there is nothing to release; - various other changes which makes forcible destruction reliable.

- 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.

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