The fixes involve the following changes:

- Unexport functions which are not utilized out of the file
  * print_path_column()
  * parse_reflink_range()
  * btrfs_list_setup_print_column()
  * device_get_partition_size_sysfs()
  * max_zone_append_size()

- Include related headers before implementing the function
  * change-uuid.c
  * convert-bgt.c
  * seed.h

- Add missing headers caused by the above header changes
  * include <uuid/uuid.h> for tune/tune.h.

a754fe29d9 btrfs-progs: sync uapi/btrfs.h into btrfs-progs
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.

bf0f3db765 btrfs-progs: introduce UASSERT() for purely userspace code
While syncing messages.[ch] I had to back out the ASSERT() code in
kerncompat.h, which means we now rely on the kernel code for ASSERT().
In order to maintain some semblance of separation introduce UASSERT()
and use that in all the purely userspace code.

f61b90aff9 btrfs-progs: make usage call properly return an exit value
[BUG]
Currently cli/009 test case failed with different exit number:

  ====== RUN CHECK /home/adam/btrfs-progs/btrfstune --help
  usage: btrfstune [options] device
  [...]
  failed: /home/adam/btrfs-progs/btrfstune --help
  test failed for case 009-btrfstune

[CAUSE]
In tune/main.c, we have the following call on usage():

  static void print_usage(int ret)
  {
	usage(&tune_cmd);
	exit(ret);
  }

However usage() itself would always call exit(1):

  void usage(const struct cmd_struct *cmd)
  {
	usage_command_usagestr(cmd->usagestr, NULL, 0, true, true);
	exit(1);
  }

This makes prevents any caller of usage() to modify its exit number.

[FIX]
Add a new argument @error for print_usage(), so we can properly return 0
for -h/--help usage.

b7e3acd615 btrfs-progs: subvol list: fix the wrong timestamp and UUID check for root items
[BUG]
Since commit d729048be6 ("btrfs-progs: stop using
btrfs_root_item_v0"), "btrfs subvolume list -u" not longer correctly
reports UUID nor timestamp, while older (btrfs-progs v6.0.2) still works
correctly:

 v6.0.2:
 # btrfs subv list -u  /mnt/btrfs/
 ID 256 gen 12 top level 5 uuid ed4af580-d512-2644-b392-2a71aaeeb99e path subv1
 ID 257 gen 13 top level 5 uuid a22ccba7-0a0a-a94f-af4b-5116ab58bb61 path subv2

 v6.1:
 # ./btrfs subv list -u /mnt/btrfs/
 ID 256 gen 12 top level 5 uuid -                                    path subv1
 ID 257 gen 13 top level 5 uuid -                                    path subv2

[CAUSE]
Commit d729048be6 ("btrfs-progs: stop using btrfs_root_item_v0")
removed old btrfs_root_item_v0, but incorrectly changed the check for
v0 root item.

Now we will treat v0 root items as latest root items, causing possible
out-of-bound access, while treating current root items as older v0 root
items, ignoring the UUID nor timestamp.

[FIX]
Fix the bug by using correct checks, and add extra comments on the
branches.

d729048be6 btrfs-progs: stop using btrfs_root_item_v0
This isn't defined in the kernel, we simply check if the root item size
is less than btrfs_root_item, so adjust the user of btrfs_root_item_v0
to make a similar check.
