fusefs: merge from projects/fuse2

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

fusefs: add a intr/nointr mount option

FUSE file systems can optionally support interrupting outstanding
operations. However, the file system does not identify to the kernel at
mount time whether it's capable of doing that. Instead it signals its
noncapability by returning ENOSYS to the first FUSE_INTERRUPT operation it
receives. That's a problem for reliable signal delivery, because the kernel
must choose which thread should get a signal before it knows whether the
FUSE server can handle interrupts. The problem is even worse because the
FUSE protocol allows a file system to simply ignore all FUSE_INTERRUPT
operations.

Fix the signal delivery logic by making interruptibility an opt-in mount
option. This will require a corresponding change to libfuse, but not to
most file systems that link to libfuse.

Bump __FreeBSD_version due to the new mount option.

fusefs: enable write clustering

Enable write clustering in fusefs whenever cache mode is set to writeback
and the "async" mount option is used. With default values for MAXPHYS,
DFLTPHYS, and the fuse max_write mount parameter, that means sequential
writes will now be written 128KB at a time instead of 64KB.

Also, add a regression test for PR 238565, a panic during unmount that
probably affects UFS, ext2, and msdosfs as well as fusefs.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
