[BUG]
There is a long existing failure in my local VM that with any newer
kernel (6.x) the test case misc/004 would fail with ENOSPC during
balance:
[TEST] misc-tests.sh
[TEST/misc] 004-shrink-fs
failed: /home/adam/btrfs-progs/btrfs balance start -mconvert=single -sconvert=single -f /home/adam/btrfs-progs/tests/mnt
test failed for case 004-shrink-fs
make: *** [Makefile:547: test-misc] Error 1
[CAUSE]
With more testing, it turns out that just before the balance, the
filesystem still have several empty data block groups.
The reason is the new default discard=async behavior, as it also changes
the empty block groups to be async, this leave the empty block groups
there, resulting no extra space for the convert balance.
[FIX]
I do not understand why for loop block devices we also enable
discard, but at least disable discard for the test case so that we can
ensure the empty block groups get cleaned up properly.

Executing the script inside the directories as './test.sh' is not
supposed to work but could happen accidentally. With an exit after
attempting to source the we can fix that.

Since run_check_stdout() can insert INSTRUMENT for all btrfs related
programs, which could easily pollute the stdout, any caller of
run_check_stdout() should do proper filter.
The following callers are affected:
- misc/004
Filter the output of "btrfs ins min-dev-size"
- misc/009
- misc/013
- misc/024
They are all calling "btrfs ins rootid", so introduce get_subvolid()
function to grab the subvolid properly.
- misc/031
Loose the filter for "btrfs qgroup show". No need for "tail -n 1".
So we still have the same coverage, but now these tests won't cause
false alert if we insert INSTRUMENT for all btrfs commands.

Use TEST_TOP as base for tests to reference any files, this will be used
for git and external testsuite.
INTERNAL_BIN is needed for referencing binaries that could reside in
different paths in git vs external testsuite.

Previously in 'filesystem resize get_min_size', now
'inspect-internal min-dev-size'. We'd like to avoid cluttering the
'resize' syntax further.
The test has been updated to exercise the new option.

Currently there is not way for a user to know what is the minimum size a
device of a btrfs filesystem can be resized to. Sometimes the value of
total allocated space (sum of all allocated chunks/device extents), which
can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage',
works as the minimum size, but sometimes it does not, namely when device
extents have to relocated to holes (unallocated space) within the new
size of the device (the total allocated space sum).
This change adds the ability to reliably compute such minimum value and
extents 'btrfs filesystem resize' with the following syntax to get such
value:
btrfs filesystem resize [devid:]get_min_size
