Remove btrfs_qgroup_inherit_add_copy() and the command line interface.
This was designed to add a pair of source/destination qgroups into
btrfs_qgroup_inherit structure, so that rfer/excl numbers would be
copied from the source qgroup into the destination one.
This behavior has been intentionally hidden since 2016, as such copy will
cause qgroup inconsistent immediately and a rescan would reset whatever
numbers copied anyway.
Now we're going to reject the copy behavior from kernel, there is no
need to keep those hidden (and already disabled for "subvolume create")
case.
Remove btrfs_qgroup_inherit_add_copy() call, and cleanup the
undocumented options.

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.

This reverts commit 03451430de.
(It's not 1:1, there are some additional trivial fixups in cmds/qgroup.c)
This breaks a lot of 3rd party tools that depend on it as Neal reports:
* btrfs-assistant
* buildah
* cri-o
* podman
* skopeo
* containerd
* moby/docker
* snapper
* source-to-image

We're going to sync the kernel source into btrfs-progs, and in the
kernel we have all these qgroup fields named with short names instead of
the full name, so rename
referenced -> rfer
compressed -> cmpr
exclusive -> excl
to match the kernel and update all the users, this will make the sync
cleaner.
ioctl.h is a public header but there are no users of the
btrfs_qgroup_limit structure.

Move everything related to the output formatting and filtering out of
qgroup.h and leave only the structures used by the public API.

After merging the files, many functions can be made static, leaving only
a few helpers that are used by subvolume.

There are declarations that are namely for the command line out put,
filters and formatting. Move it to cmds/.
