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.

The test could occasionally hang if the parent's SIGUSR2 signal arrived
before the child had pause()d. Using POSIX semaphores precludes that
possibility.

If a FUSE filesystem returns ENOSYS for FUSE_CREATE, then fallback to
FUSE_MKNOD/FUSE_OPEN.
Also, fix a memory leak in the error path of fuse_vnop_create. And do a
little cleanup in fuse_vnop_open.

The FUSE protocol allows for LOOKUP to return a cacheable negative response,
which means that the file doesn't exist and the kernel can cache its
nonexistence. As of this commit fusefs doesn't cache the nonexistence, but
it does correctly handle such responses. Prior to this commit attempting to
create a file, even with O_CREAT would fail with ENOENT if the daemon
returned a cacheable negative response.

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.

It's sufficient to check for /dev/fuse. And due to bug 236647, the module
could be named either fuse or fusefs.

Also, fix one of the default_permissions test cases. I forgot the
expectation for FUSE_ACCESS, because that doesn't work right now.

Now the entire fuse test suite can "pass", or at least not fail. Skipped
tests are reported to Kyua as passes, because googletest is still using
Kyua's plain test adapter.

Sometimes the fuse daemon doesn't die as soon as its /dev/fuse file
descriptor is closed; it needs to be unmounted first.

Revision r345269 introduced changes that triggered a regression on netmap
unit tests (tests/sys/netmap/ctrl-api-test.c).
This change updates the unit tests to remove the regression.

This commit adds tests for the default_permissions and push_symlinks_in
mount options. It doesn't add tests for allow_other, because I'm not sure
how that will interact with Kyua (the test will need to drop privileges).
All of the other mount options are undocumented.

This required changing the way that all operations are mocked. Previously
MockFS::process had one input argument and one output argument. Now, it
returns a vector of zero or more responses. This allows tests to simulate
conditions where the filesystem daemon has a queue depth > 1.
