0371b047f9 change from fasthash64 to wyhash
wyhash has very good performance for small keys (our usecase) and
works on platforms with alignment concerns.

A user had an issue where fasthash64 lead to misaligned reads and
signal exceptions. wyhash does not have such issues and is faster.

93218a343a NFS open/creat hack
A hack to work around non-POSIX NFS <-> FUSE behavior where it turns
an open(O_EXCL|O_CREAT,0444) into multiple calls that results in
EACCES.

3ec137c4ad policy: add "most shared path" policies
Like path preserving but walks back the path till a match is found. Should
cover the usecase where someone wants a "less strict" form of path
preservation.

08d267fc61 moveonenospc: enhance the feature to allow using a policy
Just like functions you can now set a policy for moveonfreenospc. This
allows for more flexibility.

For backwards compatibility moveonfreenospc=true is converted to
moveonfreenospc=mfs.

minfreespace does apply which is slightly different from original behavior.

speeds depending on the workload.

6ecc618d83 remove .fuse_hidden file creation
addresses #521

mergerfs is written using libfuse's high level API. The HLAPI forces a certain
behavior with regard to unlinking or rename overwriting of open files. It
renames the file to .fuse_hiddenXXXXXX and when incoming requests refer
to the unlinked file it will use path based calls and use that path.

This behavior leads to rmdirs failing or some software noticing
the .fuse_hidden files.

This patch changes the HLAPI and removes entirely the .fuse_hidden behavior.

See the README for more.

c5b2415daf remove defaults, hard code atomic_o_trunc, big_writes, and default_permissions
`defaults` is a value used by all filesystems and isn't passed through to
mergerfs when mounting via the fstab or the mount command. This led
to inconsistent application of options. atomic_o_trunc, big_writes, and
default_permissions should be enabled all the time anyway and splice_*
can lead to issues so they are not always enabled.

93f7d7d927 add link_cow feature
When enabled if a regular file is opened which has a link count > 1 it will
copy the file to a temporary file and rename over the original. Effectively
breaking the link. This behavior is similar to cow-shell and other LD_PRELOAD
based "CoW" solutions.

options: move "-o threads=" help text to libfuse/
Parsing of and acting upon "-o threads" option is done in the bundled `libfuse/`,
so move the corresponding help text there too.
This make help text consistent with behavior
when building against system libfuse,
which doesn't support this option.
