Some devices scale the frequency based on the input and will provide
recordings with different frequencies each time. Recommend to measure multiple
times since we can only know what the highest frequency is.

Relative devices don't provide a physical resolution to the host. For things
like pointer acceleration, the physical amount of movement is better as
baseline than the movement in device units.
Alas, many devices don't come with any information at all, so the users have
to guess. Help that guesswork by providing a tool that does the calculations
for them.
This tool measures the device units covered, then prints the frequency and an
lookup table for various resolutions (in dpi) to match to the physical
movement of the device.

Merge potentially useful patterns taken from other projects.
Some application specific patterns were move to their respective directories.
The only noticeable change is that *.patch is ignore to prevent accidental
checkin of patches. The pattern "test-driver" could not be found and was
removed.
The test directory had not been updated since the move of all test cases
in a single binary.

These are deprecated, but were missing the deprecated attribute.
And fix up the tests that were still using those deprecated calls.

Rename from LIBEVDEV_READ_foo to LIBEVDEV_READ_FLAG_foo to differentiate
better from LIBEVDEV_READ_STATUS_foo.

Improved readability in callers, changing magic numbers 0 and 1 to
rc = libevdev_next_event();
if (rc == LIBEVDEV_READ_STATUS_SUCCESS)
do_something();
else if (rc == LIBEVDEV_READ_STATUS_SYNC)
do_something_else()
No ABI changes, the enum values are the previously documented values,
this is just a readability improvement.

Another look at the current API showed some inconsistencies, rectified
in this commit:
libevdev_kernel_*: modify the underlying kernel device
libevdev_event_type_*: something with an event type
libevdev_event_code_*: something with an event code
libevdev_event_*: struct input_event-related functions (i.e. not device-related)
libevdev_property_*: something with a property
libevdev_*: anything applying to a device
Hopefully that's the last API change. Current symbols deprecated and aliased.

Not all clients need nonblocking read, so add a flag to read
in blocking mode. In that mode, events are only read from the fd when
the queue is empty.
