Our implementation of RTMPE is heavily based on librtmp.

This makes sure these calls are removed by dead code elimination
even if optimization is disabled. This fixes building without
crypto libraries without optimization.

Most people know the codec as "AAC" and not "Advanced Audio Coding".

The ffrtmpcrypt protocol depends on external libraries, which are
also required to compile the header file.

The rtmpts protocol uses https implicitly, via the ffrtmphttp
protocol, but the ffrtmphttp protocol is also useable for plain
rtmpt without https, so the dependency needs to be added here instead.

If using a different sample rate or number of channels, use a dynamic
payload type instead, where the parameters are passed in the SDP.

G722 is a special case where the normal rules don't apply.

Set picture type before calling get_buffer.
This allows the DR application to make better decisions.
It also fixes a resource leak in case of missing reference frames
since it would call get_buffer but never release_buffer.
Also use FFSWAP to ensure that the AVFrame is properly initialized
in the next get_buffer (in particular that data[0] is NULL).

If st is NULL, it means no 'fmt ' tag is found, but 'data' tag (which
needs a previous 'fmt ' tag to be parsed correctly and st initialized)
check will make sure st is never dereferenced in that case.

Write out the NAL decoding loops in full so that they are easier
to parse for a preprocessor without it having to be aware of macros
or other such things in C code.

This also makes the code more readable.

This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPE protocol implementation uses ffrtmpcrypt:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.

The function called in this block is under HAVE_INLINE_ASM itself also.

This allows compiling this code using compilers that do not understand
gcc-style inline assembly.

The files do not contain only MMX code.

This removes the use of macro nesting in these code constructs, which
makes it easier to parse in pre-processors.

Simplifies pshufb masks that operate on words.

Use compiler-specific replacements for the -o flag in check_cc.
This makes tests work properly with compilers using non-standard
flags.

The tms470 flags are updated to work with this scheme.

Nellymoser is float, so use oneoff comparison instead of md5.

The flag was added to avoid excessive warning spam, but nowadays those
warnings no longer occur in such large numbers as to require silencing.
Besides, gcc-specific flags do not belong in the Makefiles.
