We were reusing a structure for multiple operations, but failing to
reinitialize one member. The result is that a server that cares about FUSE
file handle IDs would see one correct FUSE_FSYNC operation, and one with the
FHID unset.

closing a file descriptor causes FUSE activity that is superfluous to the
purpose of most tests, but would nonetheless require matching expectations.
Rather than do that, most tests deliberately leak file descriptors instead.
This commit moves the leakage from each test into two trivial functions:
leak and leakdir. Hopefully Coverity will only complain about those
functions and not all of their callers.

This bit tells the server that we're not sure which uid, gid, and/or pid
originated the write. I don't know of a single file system that cares, but
it's part of the protocol.

For many FUSE opcodes, an error of ENOSYS has special meaning. fusefs
already handled some of those; this commit adds handling for the remainder:
* FUSE_FSYNC, FUSE_FSYNCDIR: ENOSYS means "success, and automatically return
success without calling the daemon from now on"
* All extattr operations: ENOSYS means "fail EOPNOTSUPP, and automatically
do it without calling the daemon from now on"

FUSE_LOOKUP, FUSE_GETATTR, FUSE_SETATTR, FUSE_MKDIR, FUSE_LINK,
FUSE_SYMLINK, FUSE_MKNOD, and FUSE_CREATE all return file attributes with a
cache validity period. fusefs will now cache the attributes, if the server
returns a non-zero cache validity period.
This change does _not_ implement finite attr cache timeouts. That will
follow as part of PR 235773.

These tests were actually fixed by r345398, r345390 and r345392, but I
neglected to reenable them. Too bad googletest doesn't have the notion of
an Expected Failure like ATF does.

The FUSE protocol says that FUSE_FLUSH should be send every time a file
descriptor is closed. That's not quite possible in FreeBSD because multiple
file descriptors can share a single struct file, and closef doesn't call
fo_close until the last close. However, we can still send FUSE_FLUSH on
every VOP_CLOSE, which is probably good enough.
There are two purposes for FUSE_FLUSH. One is to allow file systems to
return EIO if they have an error when writing data that's cached
server-side. The other is to release POSIX file locks (which fusefs(5) does
not yet support).

fuse_vnop_create must close the newly created file if it can't allocate a
vnode. When it does so, it must use the same file flags for FUSE_RELEASE as
it used for FUSE_OPEN or FUSE_CREATE.

For an unknown reason, fusefs was _always_ sending the fdatasync operation
instead of fsync. Now it correctly sends one or the other.
Also, remove the Fsync.fsync_metadata_only test, along with the recently
removed Fsync.nop. They should never have been added. The kernel shouldn't
keep track of which files have dirty data; that's the daemon's job.
