new features: follow-symlinks, rename-exdev, link-exdev
* follow-symlinks: allows mergerfs to transparently follow symlinks
* link-exdev: in the event a link returns EXDEV create a symlink instead
* rename-exdev: in the event a rename returns EXDEV move the oldpath and
create a symlink for the newpath

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

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.

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.

move on enospc when writing feature. closes #141
This feature mimics the standard mhddfs behavior but is more thorough.
If a write fails and the errno is set to ENOSPC then mergerfs will (if
the feature is enabled) attempt to move the file to the drive with
the most free space but only if it has enough room for the file plus
the amount to be written. If that transfer is successful it will then
unlink the original file and attempt the previously failed write again.
The copy includes copying the path and file including the acls, owners,
attributes, extended attributes, and timestamps.
