Add a copy from v6.0.2 of kerncompat.h for libbtrfs to avoid accidental
build breakage as it's a public header and until now also shared with
the rest of btrfs-progs code.

The file ioctl.h has been copied to libbtrfs in 5fc1d0cd64
("btrfs-progs: copy ioctl.h into libbtrfs") but that was after changes
to the btrfs_qgroup_limit in 03451430de ("btrfs-progs: rename qgroup
items to match the kernel naming scheme"). This caused build breakage
but hasn't been fixed in v6.1.1.
Revert the contents of libbtrfs/ioctl.h to be completely just v6.0.2
though the other changes may not be needed, it's the version we know
works.

We're going to sync btrfs.h into btrfs-progs from the kernel, however
libbtrfs still needs ioctl.h. To deal with this copy ioctl.h into
libbtrfs, and update that code to use the local copy and update the
libbtrfs headers list to use this copy.

We return __u16 in the kernel, as this is actually the size of
btrfs_qgroup_level. Adjust the existing helpers and update all the
callers to deal with the new size appropriately. This will make syncing
the kernel code cleaner.

Kernel function name is btrfs_qgroup_subvolid so rename it in progs. The
libbtrfs can't API be changed without versioning so at least add the new
helper.

The radix-tree is not used in userspace code. In kernel it's for
tracking unpersisted and in-memory structures and has been replaced by
the xarray.

The header extent-cache.h is internal and provides only structures defined
in ctree.h, we don't need anything else besides the structures.

The header extent_io.h is internal and provides only structures defined

Let libbtrfs use own copy of the exported header files to avoid
potential breakage when syncing with kernel headers and also to remove
declarations that are not used by userspace. The send.h is frozen to
support protocol v1.

Copy the lookup helper and switch the API functions using it. We can
drop dependency on kernel-shared/uuid-tree.c after that.

There are two functions for resolving subvolume id path, but one is less
convenient and pulls a lot of dependencies. This is
btrfs_list_path_for_root, where the idea is to have the whole tree of
subvolumes and query it as needed.
For simple path resolution we already have btrfs_subvolid_resolve and
it's also in the public API, so we can use it and drop the other one.
This in turn allows to drop btrfs-list.o from build dependencies.

The two files send-stream and send-utils contain the implementations of
the exported API, which was just for send stream. This was the original
idea. That libbtrfs contains another 40 files was a result of
unclean/missing library design and had to be done that way to resolve
the symbols due to dependencies.
That the same files have been used for both internal and public library
has prevented refactoring and cleanups and was always a risk of breaking
something.
Make separate copy for libbtrfs utils and allow any cleanups and
reduction of number of build objects. The API hasn't changed since the
beginning so there's low risk of missing some fixes from the internal
code.
