As per issue2629, most 23.976fps matroska H.264 files are incorrectly
detected as 24fps, as the matroska timestamps usually have only
millisecond precision.

Fix that by doubling the amount of timestamps inspected for frame rate
for streams that have coarse time base. This also fixes 29.970 detection
in matroska.

This adds a "fate" make target which runs the full FATE test suite.
Individual tests can be run with "make fate-$testname".

The location of the FATE test samples must be specified with the
--samples=PATH option to configure.

The tests/fate-update.sh script regenerates the references files and
test list from the online FATE database.  These are checked in since
generating them requires non-standard tools.
