expression howmany(BBSIZE, PAGE_SIZE), where BBSIZE is the size of the
boot block area. That can be less than 2 if PAGE_SIZE is big.
swapon(8) has an option to trim (delete) all the blocks of a device at
startup. However, if the first of those blocks is a bsd label, then
trimming those blocks is destructive. Change swapon to leave the
first BBSIZE bytes untrimmed.
Update manual pages to reflect changes in how swapon and how it may be
used, espeically in association with savecore.

Make a note in the newfs.8 manual page to update the first backup
superblock location when changing the default fragment size for
the filesystem.
Reported by: O. Hartmann
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.

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

I merged passthru.c from the wrong branch (it was a branch that went further in
a direction I wound up not taking). Fix the mismerge and turn passthru on.
NVMe reservations are quite alike to SCSI persistent reservations and
can be used in clustered setups with shared multiport storage.

r348215 changed jail_getid(3) to validate passed-in jids as active jails
(as the function is documented to return -1 if the jail does not exist).
This broke the jail option (in some cases?) as the jail historically hasn't
needed to exist at the time of rule parsing; jids will get stored and later
applied.
Fix this caller to attempt to parse *av as a number first and just use it
as-is to match historical behavior. jail_getid(3) must still be used in
order for name arguments to work, but it's strictly a fallback in case we
weren't given a number.

It allows to delete all user data from NVM subsystem in one of 3 methods.
It is a close equivalent of SCSI SANITIZE command of `camcontrol sanitize`,
so I tried to keep arguments as close as possible.
While there, fix supported sanitize methods reporting in `identify`.

Add few new arguments to `nvmecontrol log` subcommand.
MFC after: 2 weeks
Sponsored by: iXsystems, Inc.
While very useful by itself, it also makes `nvmecontrol` not depend on
hardcoded device names parsing, that in its turn makes simple to take
nvdX (and potentially any other) device names as arguments.
Also added IOCTL bypass from nvdX to respective nvmeYnsZ makes them
interchangeable for management purposes.

This adds several previously missed but important subcommands to list
namespaces and controllers. It also fixes few previously added but
just found with real testing to be broken subcommands.
Also while there, add possibility to explicitly specify nsid for
`nvmecontrol identify` subcommand. It may be useful to specify nsids
not having own devices, for example 0xffffffff, or just newly created
ones.

While old devices may not support 10 byte MODE SENSE/MODE SELECT commands,
new ones may not be able to report all mode pages with 6 byte commands.
This patch makes camcontrol by default start with 10 byte commands and
fall back to 6 byte on ILLEGAL REQUEST error, or 6 byte can be forced.
