It allows to read and write block descriptors alike to mode page parameters.
It allows to change block size or short-stroke HDDs or overprovision SSDs.
Depenting on -P parameter the change can be either persistent or till reset.
In case of block size change device may need reformat after the setting.
In case of SSD overprovisioning format or sanitize may be needed to really
free the flash.

During implementation appeared that csio_encode_visit() can not handle
integers of more then 4 bytes, that makes 8-byte LBA handling awkward.
I had to split it into two 4-byte halves now.

Some hardware needs more than 32, bump this value.

We cannot use the _alloc for of getencprop as this function is called
too early in the boot before pmap is initialized and we only have
2k of stack when cninit is called.

The region for uart0 is declared to be 0x2000 in size but the parent
node only declare 0x1000.
As the parent only declare a size of 0x1000 in the ranges for it's children
this cause the device to not be mappable.

The low fd limit used by poudriere exposed an odd failure mode in
cap_fileargs (used by readelf as of r350516).  In particular, when
the limit was hit, both the main process and casper service would
block on their shared socket, waiting forever for the other to send a
message.

- Use keyed-md5 and keyed_sha1 instead of md5 and sha1 to match
  the names accepted by setkey and to also avoid confusion since
  these are not "plain" MD5 or SHA1.
- Remove always-true #ifdef's to make the source a bit easier to
  read.
- Add missing mappings for tcp-md5, camellia-cbc, and aes-gmac.

This commit imports the new fusefs driver. It raises the protocol level
from 7.8 to 7.23, fixes many bugs, adds a test suite for the driver, and
adds many new features. New features include:

* Optional kernel-side permissions checks (-o default_permissions)
* Implement VOP_MKNOD, VOP_BMAP, and VOP_ADVLOCK
* Allow interrupting FUSE operations
* Support named pipes and unix-domain sockets in fusefs file systems
* Forward UTIME_NOW during utimensat(2) to the daemon
* kqueue support for /dev/fuse
* Allow updating mounts with "mount -u"
* Allow exporting fusefs file systems over NFS
* Server-initiated invalidation of the name cache or data cache
* Respect RLIMIT_FSIZE
* Try to support servers as old as protocol 7.4

Performance enhancements include:

* Implement FUSE's FOPEN_KEEP_CACHE and FUSE_ASYNC_READ flags
* Cache file attributes
* Cache lookup entries, both positive and negative
* Server-selectable cache modes: writethrough, writeback, or uncached
* Write clustering
* Readahead
* Use counter(9) for statistical reporting

The exists() check guarding the invocation of ls was not working
correctly as it was expanding '$L' to determine the path of the local
modules directory.  Fix by using {} around the variable name.

Inline some of the logic from bsd.subdir.mk when invoking local module
builds.  This gives output in 'make buildkernel' the same as if there
was a Makefile in /usr/local/sys/modules with SUBDIR =
${LOCAL_MODULES}.

- Check for an invalid device (vendor is invalid) before reading the
  header type register when examining function 0 of a possible device.
- When iterating over functions of a device, reject any device whose
  16-bit vendor is invalid rather than requiring the full 32-bit
  vendor+device to be all 1's.  In practice the latter check is
  probably fine, but checking the vendor is what the PCI spec
  recommends.

- UMA_XDOMAIN enables an additional per-cpu bucket for freed memory that
   was freed on a different domain from where it was allocated.  This is
   only used for UMA_ZONE_NUMA (first-touch) zones.
 - UMA_FIRSTTOUCH sets the default UMA policy to be first-touch for all
   zones.  This tries to maintain locality for kernel memory.

RT2860_WCID_MAX is supposed to describe the max STA index for wcid2ni, and
was instead being used as the size -- off-by-one.

rt2860_drain_stats_fifo was range-checking wcid only after accessing
out-of-bounds potentially.
