Add support for FOPEN_NOFLUSH, introduced in 7.35.

Also, reduce diffs vis-a-vis upstream by factoring out an ioctl type, a
change missed in d5e3cf41e89.

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: raise protocol level to 7.15

This protocol level adds two new features: the ability for the server to
store or retrieve data into/from the client's cache. But the messages
aren't defined soundly since they identify the file only by its inode,
without the generation number. So it's possible for them to modify the
wrong file's cache. Also, I don't know of any file systems in ports that
use these messages. So I'm not implementing them. I did add a (disabled)
test for the store message, however.

fusefs: diff reduction vs the upstream sources

fuse_kernel.h defines the structures used by the FUSE protocol. Originally
it came from libfuse, but the current source of truth is the Linux kernel.
This commit minimizes the diffs between our version and the Linux version as
of 21f3da95d (protocol version 7.8).

The flags field of struct fuse_listxattr_out and fuse_listxattr_in was an
error in our header. Those fields don't exist in Linux or libfuse, and
they've never been used in FreeBSD. In fact, those structs don't even exist
in Linux and libfuse; those projects confusingly overload the identical
fuse_getexattr_in and fuse_getxattr_out structs.
