For debugging it's more important to be able to quickly run a single test
rather than grouping them together, we don't have thousands of tests here
anyway. So let's add a macro to put every test func into its own TCase,
allowing for test selection via the environment variable CK_RUN_CASE.

Previously, enabling or disabling ABS_MT_SLOT would not change the actual
slots, it was treated as a normal bitflag. This means we couldn't initialize a
libevdev context from scratch and have it behave like a correct MT context.

Two new function pairs:
libevdev_event_code_from_code_name()
libevdev_event_type_from_code_name()
libevdev_event_code_from_code_name_n()
libevdev_event_type_from_code_name_n()
These functions look up event codes/types by the name of the event code only,
removing the need to figure out what event type an event code has. So if all
you have is "BTN_TOUCH", you can now look up the type and code for that,
without having to check the prefix yourself to guess at the type.

With the previous approach, every libevdev_next_event() invocation triggered a
read() on the device fd. This is not efficient, the kernel provides whole
event frames at a time so we're guaranteed to have more events waiting unless
the current event is a SYN_REPORT.
Assuming a fast-enough client and e.g. a touchpad device with multiple axes
per frame, we'd thus trigger several unnecessary read() calls per event frame.
Drop this behavior, instead only trigger the read when our internal queue is
empty and we need more events.
Fallout:
- we don't have any warning about a too-slow sync, i.e. if a SYN_DROPPED
arrives while we're syncing, we don't get a warning in the log anymore.
the test for this was removed.
- the tests that required the specific behavior were rewritten accordingly
- a revoke on a kernel device doesn't return ENODEV until already-received
events have been processed
The above shouldn't be an issue for existing real-world clients.

They have the same value, so the _MAX code would shadow the real code, causing
issues in any client that needs to get all event names from libevdev.
Specifically, the loop of:
for each code in 0 to max-for-type:
print(name)
would not show up the code (but the _MAX) code instead. This causes issues
with clients that rely on name resolution that works. And the _MAX values are
special values anyway.
Blacklist it in the script here, causing it to resolve from name to code, but
not from code to name (like other duplicated codes).

Previously, calling grabbing a device after changing the fd was a no-op
because libevdev's grab state didn't match the fd:
libevdev_grab(LIBEVDEV_GRAB);
.. fd is grabbed
.. internal state is 'grabbed'
libevdev_change_fd();
.. new fd is ungrabbed
.. internal state is 'grabbed'
libevdev_grab(LIBEVDEV_GRAB);
.. argument matches internal state and we exit without grabbing the device

The main thing holding us back here was our gcov hacks. We used to rebuild the
libevdev sources locally inside test/ with the gcov flags so that we could
leave the main libevdev sources untouched. This doesn't work well with
subdir-objects - we have to link to libevdev.la instead.
To enable gcov, we now have to apply the gcov flags to the main library
object. But this also means that when running, the notes files will be
somewhere within the libevdev/ directory, not the test/ directory. Working
around this in automake gets nasty quickly, so just add a script that knows
how to search for things.
No functional changes unless --enable-gcov is given at configure time - then
don't install the library.
The gcov reports are now in test/gcov-reports/
