Coverity tries to supply system headers and fails badly at it. A bunch of
_Float... sizes are pulled in by math.h but not provided anywhere. So as a
workaround, let's add an option to explicitly enable coverity support that
simply #defines those types to ones we do know about and let's go on hoping
it'll eventually work.
See the equivalent addition to libinput in commit 8178339b5baa717.

v3.4 was released in 2012, every kernel since has that ioctl. So instead of
assuming you're running new libevdev on an 8 year old kernel, let's assume
that any error from the ioctl() is an actual error and handle it accordingly.

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.

This is a GNU C extension, and is not available in ISO C.

Statement expressions are a GNU C extension and are not available
in ISO C.
On compilers that don't have them, define these macros as plain
conditional expressions, since they are only ever used with expressions
that have no side-effects.
The statement-expression version is still retained as an added
safety measure on GNU-compatible compilers.

With b65be7aa79 the centos 7 RPMs don't include doxygen anymore, so let's drop
the distcheck job. Centos 7 is old enough at this point that we don't need to
care too much.

With b65be7aa79 the centos 7 RPMs don't include doxygen anymore, causing a CI
pipeline failure (but only where the centos image is being rebuilt).
Fedora is a better early-warning system about possible breakages than Centos -
which was originally chosen precisely because it doesn't update much and was
faster to run in the CI (this was before custom docker images).

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.

Revert back to the normal doxygen looks, even though they're pretty awful. But

This causes some weird rendering, let's split it into a list (which also

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.
