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:

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.

This makes the lavf tests depend on all codecs and formats they use.

This tool uses lavfi internal symbols not accessible in shared
libraries.  TESTPROGS are linked statically to allow them use of
library internals not normally exported.

A number of systems do not implement freopen() with a NULL filename
correctly.  This changes these programs to output individual images
if opening a named output argument as a file fails, in this case
assuming it is a directory.

This makes videogen/rotozoom output a raw video stream on stdout
if no output directory is specified.

The encode/decode tests should all depend on avconv.  Since
avconv requires libavfilter, there is no need to enable those
tests selectively.

This allows fate to run without errors with or without SAMPLES
being set.

This makes only tests actually using avconv depend on it.
The remaining tests already depend on what they need.

Only the probe tests should depend on avprobe and these should
be enabled only if avprobe is configured.

Avoids resampling and channel mixing. This only tests the behavior
with respect to input and output audio rather than also testing changes
to the encoder or muxer that do not affect the resulting decoded output.

This will allow for comparing decoded output to the original source when the
decoded size is not exactly the same as the original size.

This will allow comparison to original pre-encoded content instead of
comparing to expected decoded output.

This will allow adjusting for any encoder or decoder delay when doing
comparisons.
