src: port fsstress
Nishita needs this for the integrity tests. Pull in fsstress from
xfstests as of commit 64b90915304c0cc1bf60c567d46ad88728e74b42. I really
don't want the xfstests build system, so I modified fsstress.c to
include its dependencies directly instead of the xfstests "global.h"
file and added the macro necessary definitions to the Makefile
invokation.

common/scsi_debug: make helpers more useful
Generalize the helpers to make them more useful: instead of always
setting up one device, it now takes arbitrary module parameters and sets
up as many devices as requested.

Add the ability to exclude a test or whole test group from a test
run. Thus a user can explicitly decide which tests to skip like in
this example where one wants all of the 'block' group but block/001.

Save and restore sysfs knobs modified during test
This adds two new helpers, _test_dev_queue_get and _test_dev_queue_set,
which wrap access to /sys/block/$dev/queue/*. _test_dev_queue_set saves
the sysfs variable before it overwrites it, to be restored in ./check.

Simplify test groups and overhaul test running
This gets rid of the concept of test groups as used by xfstests and
renames categories into groups. If it turns out we want it back, we can
reintroduce test tags later.
This rework also has a few other effects:
- The config file is now entirely optional, as is TEST_DEVS
- prepare() and prepare_device() are renamed to {group_,}requires() and
{group_,}device_requires()
- QUICK and TIMED are now test flags instead of groups
- Running test groups is now just `./check block`

Add support for test timeout
Add a configurable per-test timeout. By default, tests will run fully.
If $TIMEOUT is set, tests may restrict themselves to that timeout. So,
e.g., `TIMEOUT=30 ./check -g quick -g timed` can be used to do a quick
sanity test without doing the full run.

check: export sysfs directory for test device
E.g., if TEST_DEV=/dev/sda, then TEST_DEV_SYSFS=/sys/block/sda, and if
TEST_DEV=/dev/nvme0n1p1, then TEST_DEV_SYSFS=/sys/block/nvme0n1 (i.e.,
we get the sysfs directory for the full device, not the partition).
blktests is heavily inspired by xfstests, with a few important
differences:
- It can run tests on multiple devices at once (serialized for now, but
this can be changed).
- It has a notion of per-device tests (e.g., for testing specific I/O
workloads that have been known to cause problems) and no-device tests
(e.g., for tests that set up pseudo-devices).
- It has documentation.
- It's not ancient, so the framework is much cleaner.
Also included is a set of "meta" tests, i.e., tests that test the
testing framework itself.
