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.

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.

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.

When enabled if a regular file is opened which has a link count > 1 it will
