The warning is printed for profiles where it's not intended (like raid0
or raid1c4). Check the correct variable for the target profiles.

Enhance --force to also skip the timeout, similar to what --full-balance
does. As this is only to warn about RAID56 that won't be necessary in
the future, don't add a separate option. The warning is still printed.

Similar to the mkfs warning, add a warning to btrfs balance convert
options, with a countdown to allow the user to have time to cancel the
operation.

The exclusive ops will not start if there's one already running. Now
that we have the sysfs export (since kernel 5.10) to check if there's
one already running, use it to allow enqueueing of the operations as a
convenience.
Supported enqueuing:
btrfs balance start --enqueue
btrfs filesystem resize --enqueue
btrfs device add --enqueue
btrfs device delete --enqueue
btrfs replace start --enqueue
This patch implements the functionality based on Goldwyn's patch
https://lore.kernel.org/linux-btrfs/?q=20200825150338.32610-4-rgoldwyn%40suse.de
but on top of previous preparatory patches.
Note that 'filesystem resize' options could confuse getopt as the
negative size change looks like a series of short options and there's no
way to make getopt ignore the short options, so there's a custom option
parser.

If the exclusive operation is available in sysfs file, check if there's
one already running. The check is done for:
- device add, remove, replace
- balance
- filesystem resize
All commands will validate arguments and check before the ioctl or
before any potentially irreversible operations (like clearing device
before replacing).

Many subcommands have their own verbosity options that are being
superseded by the global options. Update the help text to reflect that
where applicable.

The term 'mixed' is confusing as it's commonly used for mised block
group profiles created by 'mkfs.btrfs --mixed'. We're interested in
multiple profiles for each type, so use the term 'multiple'.

Add a check in some btrfs subcommands to detect if a filesystem
has mixed profiles for data/metadata/system. In this case
a warning is showed.

Move the full-balance warning to before the fork, so that the user can
see and react to it.
Notes on test:
- Don't use grep -q, as it causes a SIGPIPE during the countdown, and
the balance thus doesn't start.
- The "balance cancel" is superfluous as the last command, but it
provides some idempotence and allows adding more tests below it.
