Workaround bhyve virtual disks operation on top of GEOM providers.
GEOM does not support scatter/gather lists in its I/Os. Such requests
are cut in pieces by physio(), that may be problematic, if those pieces
are not multiple of provider's sector size. If such case is detected,
move the data through temporary sequential buffer.

bthidd: Remove unused macros from hid.c.
ASIZE() was never used, and min() stopped being used in r207812.

bthidd: Consider usage ranges when dealing with array inputs.
So far, we were always using HID_USAGE() to determine the Usage ID of a
certain HID report input item. This does not work as intended if a field
is an array and the allowed usages are specified with a usage range, as
HID_USAGE() will return 0. We need to use the field value as an index in
the usage range list in this case instead.
This makes the volume keys in a Microsoft Bluetooth Mobile Keyboard
5000 be properly recognized. The relevant part of the HID report looks
like this:
0xA1, 0x01, // Collection (Application)
0x85, 0x07, // Report ID (7)
0x05, 0x0C, // Usage Page (Consumer)
0x19, 0x00, // Usage Minimum (Unassigned)
0x2A, 0xFF, 0x03, // Usage Maximum (0x03FF)
0x95, 0x01, // Report Count (1)
0x75, 0x10, // Report Size (16)
0x15, 0x00, // Logical Minimum (0)
0x27, 0xFF, 0x03, 0x00, 0x00, // Logical Maximum (1023)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred
// State,No Null Position)
When a key such as "volume down" is pressed, the following data is
transferred through Interrupt In:
0x07 0xEA 0x00

Fix thinko/copypaste error.
When checking the length of the mutual secret password the variable for
the secret password was used by mistake. This resulted in ctld never
warning about the length of the mutual secret being wrong even if it was.

Give AHCI disk serial based on backing file path same as for virtio block.
It is still not good that they may intersect on different hosts, but that
is better then intersecting on the same host.
Rewrite virtio block device driver to work asynchronously and use the block
I/O interface.
Asynchronous operation, based on r280026 change, allows to not block virtual
CPU during I/O processing, that on slow/busy storage can take seconds.
Use of recently improved block I/O interface allows to process multiple
requests same time, that improves random I/O performance on wide storages.
Benchmarks of virtual disk, backed by ZVOL on RAID10 pool of 4 HDDs, show
~3.5 times random read performance improvements, while no degradation on
linear I/O. Guest CPU usage during test dropped from 100% to almost zero.
Modify virtqueue helpers added in r253440 to allow queuing.
Original virtqueue design allows queued and out-of-order processing, but
helpers added in r253440 suppose only direct blocking in-order one.
It could be fine for network, etc., but it is a huge limitation for storage
devices.
On parallel random I/O this allows better utilize wide storage pools.
To not confuse prefetcher on linear I/O, consecutive requests are executed
sequentially, following the same logic as was earlier implemented in CTL.
Benchmarks of virtual AHCI disk, backed by ZVOL on RAID10 pool of 4 HDDs,
show ~3.5 times random read performance improvements, while no degradation
on linear I/O.
Allow the kern.osrelease and kern.osreldate sysctl values to be set in a
jail's creation parameters. This allows the kernel version to be reliably
spoofed within the jail whether examined directly with sysctl or
indirectly with the uname -r and -K options.
Export the new osreldate and osrelease jail parms in jail_get(2).
Fix line wrap.
It works only for virtual disks backed by ZVOLs and raw devices supporting
BIO_DELETE. Virtual disks backed by files won't report this capability.
Relnotes: yes
Update most userspace consumers of capability.h to use capsicum.h instead.
auditdistd is not updated as I will make the change upstream and then do a
vendor import sometime in the next week or two.
Note that a significant fraction does not apply, as FreeBSD 10 doesn't
contain a Capsicumised ping, casperd, libcasper, etc. When these features
are merged, the capsicum.h change will need to be merged with them.

Add support for TOPOLOGY feature of virtio block device.
Passing through physical block size/offset from underlying storage allows
guest to manage proper data and I/O alignment to improve performance.
