btrfs-progs: sync uapi/btrfs.h into btrfs-progs

Browse source 
We want to keep this file locally as we want to be uptodate with
upstream, so we can build btrfs-progs regardless of which kernel is
currently installed.  Sync this with the upstream version and put it in
kernel-shared/uapi to maintain some semblance of where this file comes
from.

There are some changes that need to be synced back to kernel. A local
definition of static_assert is used to avoid compilation problems on gcc
(< 9) due to mandatory 2nd parameter.
