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.

Makefile: option for building with system libfuse 
Add INTERNAL_FUSE variable to control linking against
bundled libfuse vs external/system libfuse.
If external libfuse is requested,
`pkg-config` is used to obtain CFLAGS/LIBS/LDFLAGS and
to check that the provided external libfuse is >= 2.9.7.

This might hopefully get mergerfs closer to inclusion into distros.

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

final_ino = orig_ino | (dev << 32)

not perfect but given few filesystems use 64bit inodes nor is st_dev more than 16bit usually it should be fine
