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.

2d9c915641 Return NOTTY for all btrfs ioctl calls 
mergerfs tries to pass through ioctl calls but due to the complexity
of btrfs calls their is risk of segfaults. In the future it may be
required to whitelist all supported ioctl calls.

This makes it like all other filesystems and brings it into alignment
with libfuse3's behavior.

c9a935835f Fix query of attr during symlink 
Using getattr when follow-symlink is enabled causes invalid type to the kernel
if symlink pointed to non-symlink.

c43b464d6c Call FUSE getattr rather than syscall for extra logic 
While more efficient calling regular getattr (stat) leads to incorrect
information being returned and would not work correctly when using
symlinkify.

Merge pull request #940 from trapexit/ioctl-runtime-removal 
Remove config ioctl calls

61c2187c14 Remove config ioctl calls 
While they were going to be the new way of interacting with the runtime config
I've decided to use toml based config for mergerfs v3. In that case all updates
will happen through the config file and ioctl will only be used to load/reload
the config rather than a key:value like API.

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

Percentage Free Random Distribution

Chooses a random branch based on the available space percentage free.

IE: if branch A has 1G free and branch B has 2G then B should be chosen
twice as often.
