Bit shifts should be done on unsigned type as a matter of good practice
to avoid any problems with bit overflowing to the sign bit.

Without the change `BTRFS_IOC_SCAN_DEV` aliased with `BTRFS_IOC_FORGET_DEV`.
It's a regression introduced in fcd9142b6 "btrfs-progs: docs: formatting,
fixups, updates".
It manifests as a sudden device disappearance when device is scanned:
machine # [ 4.095032] Btrfs loaded, crc32c=crc32c-intel, zoned=no, fsverity=no
machine # ERROR: device scan failed on '/dev/vdb': No such file or directory
machine # ERROR: device scan failed on '/dev/vdc': No such file or directory
(finished: must succeed: mkfs.btrfs -d raid0 /dev/vdb /dev/vdc, in 10.31 seconds)

Add a new option --simple to 'btrfs quota enable'. If set, this enables
simple quotas instead of full qgroups by using the new ioctl command
value.

When encountering a filesystem formatted with the raid stripe tree
feature, read it from disk.
Also add the incompat declaration to the tree printer.

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.
