Add a switch which controls which operation to perform.  Useful to test
only a single feature. Also the new behavior is more self-consistent.

Do not clutter the temporary directory with files, also "/tmp" is not
always available, e.g. in Windows.

Also add the clean-test Makefile rule, which will clean the generated
files.

Put the relevant code in one chunk, also check for frame allocation
failures.

All the other examples already use the system installed headers.

The header is required for the sin() function.

Remove unused variable size from video_encode_example() function.

Fix GCC warning:
decoding_encoding.c:214:22: warning: unused variable ‘size’ [-Wunused-variable]

This should be converted to the new API

examples/encoding: List more formats to make it more clear to the reader what is not handled in libavcodec.

Adopt ISC (Internet Systems Consortium) license in place of LGPL,
consistent with the other examples.

Fabrice explicitely approved the relicensing.

Simplify.

Simplify.

So it is more clear the context of the sentence.

This is required, or avcodec_open() will abort because of invalid
sample format.

The suffix is redundant since the containing directory itself is
called "examples". Simplify.

Rename:
api-example.c    -> encoding-example.c
output-example.c -> muxing-example.c

Improve consistency.
