Some btrfs test cases use btrfs module-reload to unregister devices
in the btrfs kernel. The problem with the module-reload approach is,
if test system contains btrfs as rootfs, then you can't run these
test cases.
Patches [1] introduced btrfs forget feature which can unregister
devices without the module-reload approach.
[1]
btrfs-progs: device scan: add new option to forget one or all scanned devices
btrfs: introduce new ioctl to unregister a btrfs device
And this patch makes relevant changes in the fstests to use this new
feature, when available.

btrfs/125, btrfs/148, btrfs/157, and btrfs/158 test for raid56
behavior. We shouldn't run if the kernel doesn't have support for
them.

We were sorting numerical values with the 'sort' tool without telling it
that we are sorting numbers, giving us unexpected ordering. So just pass
the '-n' option to the 'sort' tool.
Example:
$ echo -e "11\n9\n20" | sort
11
20
9
$ echo -e "11\n9\n20" | sort -n
9
11
20

Add some helper functions to require that we can reload a given
module, and add a helper to actually do that. Refactor the existing
users to use the generics.
We need to hoist completely the behaviors of the old btrfs module
helper because we need to confirm before starting the test that we
actually can remove the module.

The tests mount the second device in the device pool but never
unmount it, causing the next test to fail.
Example:
$ cat local.config
export TEST_DEV=/dev/sdb
export TEST_DIR=/home/fdmanana/btrfs-tests/dev
export SCRATCH_MNT="/home/fdmanana/btrfs-tests/scratch_1"

The test does the following:
Initialize a RAID5 with some data
Re-mount RAID5 degraded with _dev3_ missing and write data.
Save md5sum checkpoint1
Re-mount healthy RAID5
Let balance fix degraded blocks.
Save md5sum checkpoint2
Re-mount RAID1 degraded now with _dev1_ missing.
Save md5sum checkpoint3
Verify if all three md5sum matches
