84592a9f13 Remove splicing features 
After numerous tests it was found the splice features were at best
the same performance as standard IO and at worse actually slower.
To simplify the code all splice features are removed.

large portion of the time.

930dad31de 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.

8adebc9489 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

c4a85f5fad 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.
