Remove embedded name in node struct
The 32 byte array is below the average size so those 32 bytes are wasted a
large portion of the time.

Reduce struct node size
* Replace the stat values with a crc32b of them instead (for auto-cache)
* Replace char flag with bitfield
* Remove node generation. nodeid is an unsigned 64bit int. Would take 500K+ years
to rollover at 1M nodes per second.

new features: follow-symlinks, rename-exdev, link-exdev
* 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

readdir: add dirent index array
This removes the risk of corrupted data being sent back to the kernel
should it use the offset from one opendir-readdir in another. In this case
it would at most skip dirents.
According to the standards the offset is only valid when used within
the opendir -> releasedir but NFS uses offsets across independent
calls.

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.
