Merge pull request #940 from trapexit/ioctl-runtime-removal

61c2187c14 Remove config ioctl calls 
While they were going to be the new way of interacting with the runtime config
I've decided to use toml based config for mergerfs v3. In that case all updates
will happen through the config file and ioctl will only be used to load/reload
the config rather than a key:value like API.

* follow-symlinks: allows mergerfs to transparently follow symlinks

* rename-exdev: in the event a rename returns EXDEV move the oldpath and
  create a symlink for the newpath

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.

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.

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.

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.

c8fa51c81a support setting of inodes (using use_ino option) 
creates a 64bit inode value from the underlying device value + original inode
