4ca1c0b7f7 fusefs: fix some minor Coverity CIDs in the tests
Where open(2) is expected to fail, the tests should assert or expect that
its return value is -1.  These tests all accepted too much but happened to
pass anyway.

7fc0921d7e fusefs: annotate deliberate file descriptor leaks in the tests
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.

a4856c96d0 fusefs: raise protocol level to 7.12
This commit raises the protocol level and adds backwards-compatibility code
to handle structure size changes.  It doesn't implement any new features.
The new features added in protocol 7.12 are:

* server-side umask processing (which FreeBSD won't do)
* asynchronous inode and directory entry invalidation (which I'll do next)

29edc611c1 fusefs: make the tests more cplusplusy
* Prefer std::unique_ptr to raw pointers
* Prefer pass-by-reference to pass-by-pointer
* Prefer static_cast to C-style cast, unless it's too much typing

16bd2d47c7 fusefs: Upgrade FUSE protocol to version 7.9.
This commit upgrades the FUSE API to protocol 7.9 and adds unit tests for
backwards compatibility with servers built for version 7.8.  It doesn't
implement any of 7.9's new features yet.

d5ff268834 fusefs: create sockets with FUSE_MKNOD, not FUSE_CREATE
libfuse expects sockets to be created with FUSE_MKNOD, not FUSE_CREATE,
because that's how Linux does it.  My first attempt at creating sockets
(r346894) used FUSE_CREATE because FreeBSD uses VOP_CREATE for this purpose.
There are no backwards-compatibility concerns with this change, because
socket support hasn't yet been merged to head.

002e54b0aa fusefs: clear a dir's attr cache when its contents change
Any change to a directory's contents should cause its mtime and ctime to be
updated by the FUSE daemon.  Clear its attribute cache so we'll get the new
attributs the next time that they're needed.  This affects the following
VOPs: VOP_CREATE, VOP_LINK, VOP_MKDIR, VOP_MKNOD, VOP_REMOVE, VOP_RMDIR, and
VOP_SYMLINK

cad677915f fusefs: cache file attributes
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.

2d445be156 fusefs: test that open(2) can return a writable fd for a readonly file
Surprisingly, open(..., O_WRONLY | O_CREAT, 0444) should work.  POSIX
requires it.  But it didn't work in early FUSE implementations.  Add a
regression test so that our FUSE driver doesn't make the same mistake.

19ef317d62 fusefs: fallback to MKNOD/OPEN if a filesystem doesn't support CREATE
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.

6248288e97 fusefs: correctly handle cacheable negative LOOKUP responses
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.
