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.

* 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

e5b50fe736 fusefs: Make fuse file systems NFS-exportable
This commit adds the VOPs needed by userspace NFS servers (tested with
net/unfs3).  More work is needed to make the in-kernel nfsd work, because of
its stateless nature.  It doesn't open files prior to doing I/O.  Also, the
NFS-related VOPs currently ignore the entry cache.

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.

35cf0e7e56 fusefs: fix a panic in VOP_READDIR
The original fusefs import, r238402, contained a bug in fuse_vnop_close that
could close a directory's file handle while there were still other open file
descriptors.  The code looks deliberate, but there is no explanation for it.
This necessitated a workaround in fuse_vnop_readdir that would open a new
file handle if, "for some mysterious reason", that vnode didn't have any
open file handles.  r345781 had the effect of causing the workaround to
panic, making the problem more visible.

This commit removes the workaround and the original bug, which also fixes
the panic.

363a74163b fusefs: allow opening files O_EXEC
O_EXEC is useful for fexecve(2) and fchdir(2).  Treat it as another fufh
type alongside the existing RDONLY, WRONLY, and RDWR.  Prior to r345742 this
would've caused a memory and performance penalty.

e0bec057db fusefs: correctly set fuse_release_in.flags in an error path
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 old formula was unnecessarily restrictive.
