7cbd88ac81 allow setting of 'max_pages' (via 'fuse_msg_size') 
Linux 4.20 and above allow setting the number of pages per FUSE message
upto 256 (4K * 256 = 1MiB). This can greatly increase read and write
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.
