The new name is more consistent with the codebase, and more
self-consistent with the libswscale API.

Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.

Fix warnings:
muxing.c: In function ‘write_video_frame’:
muxing.c:326:23: warning: passing argument 2 of ‘sws_scale’ from incompatible pointer type [enabled by default]

Make add_{audio,video}_stream return the found codec, and pass it to
avcodec_open2() through open_{audio,video} functions.

Fix failure:
No codec provided to avcodec_open2().
could not open codec

This is also consistent with the use of the avcodec_open2() API in the
codebase.

Use avpicture_alloc() high level function.

All the other examples already use the system installed headers.

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

The new function accepts a slightly more intuitive order of paramters,
and returns an error code, thus allowing applications to report a
meaningful error message.

Make AVIO_FLAG_ access constants work as flags, and in particular fix
the behavior of functions (such as avio_check()) which expect them to
be flags rather than modes.

This breaks API.
