Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.

It provides the following features:
 * verify correctness by comparing output to the C version.
 * detect failure to save and restore clobbered callee-saved registers.
 * detect 32-bit parameters being used as if they were 64-bit in x86-64
   (the upper halves are not guaranteed to be zero - but in practice
   they very often are, which makes those bugs hard to spot otherwise).
 * easy benchmarking.

Compile by running 'make checkasm'.
Execute by running 'tests/checkasm/checkasm'.

Optional arguments are '--bench' to run benchmarks for all functions,
'--bench=<pattern>' to run benchmarks for all functions that starts with
<pattern>, and '<integer>' to seed the PRNG for reproducible results.

Contains unit tests for most h264pred functions to get started, more tests
can be added afterwards using those as a reference.

Loosely based on code from x264. Currently only supports x86 and x86-64,
but additional architectures shouldn't be too much of an obstacle to add.

Note that functions with floating point parameters or floating point
return values are not supported. Some compiler-specific features or
preprocessor hacks would likely be required to add support for that.

This makes the default of '1' more explicit than defaulting to '1' in
fate-run.sh and regression-funcs.sh if THREADS is not set.
Fixes the reported thread count in fate-cpu if THREADS is not set.

This allows running all the tests individually and/or in parallel.

Only check dependencies if invoking the make targets 'check'
or anything matching 'fate%' except 'fate-rsync'.

If building out of tree, make sure the filter scripts are copied
into the build tree before running tests. This makes sure that
SRC_PATH doesn't need to exist on the remote system (or doesn't
need to exist at the same path).

Without this, lcov sometimes misses to normalize paths that contain "/./".
Also, ignore uninteresting hits in system headers.

In the default settings, both tools produce a lot of unhelpful noise.

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this
integration was heavily inspired from the blog entry by Mike Melanson:
http://multimedia.cx/eggs/using-lcov-with-ffmpeg/

Useful to add or update fate tests.

Now that libavutil can be disabled, this should be conditional.

This causes make to exit with an error message if a nonexistent
dependency is specified rather than silently dropping the test.
