4ec2947cc9 test: add per-device udev rule support
Don't rely on a magic version tag, instead let a device define a udev rule and
drop that into the udev runtime directory before the device is created.

There are a couple of caveats with this approach: first, since this changes
system-wide state it may cause issues on the device the test suite is run on.
This can be avoided if the udev rules have filter patterns that ensure only
test devices are affected.

Second, the check test suite aborts but it doesn't run the teardown() function
if a test fails. So far this wasn't a problem since uinput devices disappear
whenever we exit. The rules files will hang around though, so an unchecked
fixture was added to delete all litest-foo.rules files before and after a test
case starts. Unchecked fixtures are run regardless of the exit status of the
test but run in the same address space - i.e. no ck_assert() usage.

Also unchecked fixtures are only run once per test-case, not once per test
function. For us, that means they're only run once per device (we use the
devices as test case), i.e. if a test fails and the udev rule isn't tidied up,
the next test may be unpredictable. This shouldn't matter too much though.

d1cc84265b test: add a semi-mt Alps test device
Provides the bounding box only, with slot 0 always being the upper/left, slot
1 being the lower-right touch. This needs to use the touch_down etc. litest
interfaces, which are now widened to double (leftover from 489630f58) and a
device-specific private pointer in the litest device.

New device feature for litest: LITEST_SEMI_MT

489630f58b test: widen litest to use doubles for scaled variables
Using a 0-100% range is useful but in some cases we need events with finer
than 1% granularity.

And fix up the two-finger test that now fails. This was a bug in the test
anyway, the dx/dy supplied here was 1% of the touchpad width. Confined to
integers this meant we only ever had the touch down, then the single move by
1%. That caused two events - not enough to satisfy tp_estimate_delta, so we
always had a delta of 0/0 regardless of the size of the move.

Now with doubles this fails, so drop it to 0.1% instead, which is small enough
on all touchpads we currently have.

a242d68989 test: allow for description-based test devices
Most of the test devices now are static descriptions anyway, make them fully
static now, including for touch events.

Switch the synaptics device now as example, the rest comes later for easier
patch review.

3a344169bb Add a device test suite
A rather large commit, copied from a similar (almost identical) suite in
libtouchpad and ported for libinput.

The goal here is to make testing for various devices easy, so the litest
("libinput test") wrappers do that. The idea is that each device has some
features, and tests are likely to exercise some features or won't work with
other features.

Each test case takes a list of required features and a list of excluded
features. The test suite will create a new test case for each device in the
suite that matches that set.

For example, the set of required LITEST_TOUCHPAD, excluded LITEST_BUTTON would
run on clickpads only, not on touchpads with buttons.

check supports suites and test cases, both named. We wrap that so that each
named set of cases we add are a test suite, with the set of devices being the
test cases. i.e.

litest_add("foo:bar", some_test_function, LITEST_ANY, LITEST_ANY);

adds a suite named "foo:bar" and test cases for both devices given, with their
shortnames as test case name, resulting in:
   "foo:bar", "trackpoint"
   "foo:bar", "clickpad"
   ...

Multiple test functions can be added to a suite. For tests without a device
requirement there is litest_add_no_device_test(...).

The environment variables CK_RUN_SUITE and CK_RUN_CASE can be used to narrow
the set of test cases. The test suite detects when run inside a debugger and
disables fork mode (the default).
