Some macOS specific features require FUSE API modifications and
extensions that break compatibility with the vanilla FUSE API. Setting
the compile-time flag FUSE_DARWIN_ENABLE_EXTENSIONS to 0, when building
a file system, disables those API extensions. By default, the macOS
specific API modifications and extensions are enabled.
macFUSE will create the mounpoint (in case it does not exist) before
mounting the volume. This allows unprivileged users to mount volumes
under /Volumes.
Windows native OpenSSH has alternative behavior for standard I/O
descriptors, which can be selected through the OPENSSH_STDIO_MODE
environement variable. Setting it to "nonsock" is required for
sshfs compatibility.

for details.
Uncached and cached results for readdir were inconsistent -- the former
returned correct stat info for directory entries while the latter
didn't. That's because only names of entries were saved in cache without
stat info. In turn this leads to issues like
https://github.com/junegunn/fzf/issues/3832 since directory traversal
library (https://github.com/charlievieth/fastwalk in this case) relies
on proper stat info returned by readdir. Hence when unchached result was
returned it gave proper outcome, while with cached result it was wrong.
Cache stat info next to entry name to fix the issue. While file
attributes are saved in cache already, they use full path as key. To
avoid potentially plenty of allocations, string copying and cache
lookups to get each attr, let's keep a copy of stat struct independently
to be on the fast path.
"sshfs -o vsock=CID:PORT" will cause sshfs to connect directly to the
given vsock, bypassing ssh, and allowing high performance sshfs mounts
of a VM guest.
Added a secondary check so if a mkdir request fails with EPERM an access request will be tried - returning EEXIST if the access was successful. This matches the correct behaviour expected by applications such as git.

If ssh is configured to use "Match exec" and the previous working
directory is the mount point, then the shell (bash) hangs calling
stat() on OLDPWD.
Unset OLDPWD so that this doesn't happen.
Fixes#206.
