522d65ba25 rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions. 
Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.

e2bad983b5 swscale: reformat x86/swscale_template.c. 
Interleave macros and code so that it's easier to find the
actual code that belongs to a function. Also reindent where
appropriate and remove dead code.

acb96bc268 swscale: remove if (c->dstFormat) branch from yuv2packed[12X](). 
This allows cutting up the function in much smaller and easier-
to-maintain chunks.

b6cac9b3bf swscale: remove if(full_chr_int) from yuv2packed1(). 
If that flag is set, swScale() already proxies the call to
yuv2rgbXinC_full(). Therefore, this flag is never set when
yuv2packed1() is called.

db3262b700 ffserver: Fix a null pointer dereference as a result of the FF_API_MAX_STREAMS cleanup. 
Fixed another dereference in the RTSP code.

Removed a useless variable.

Changed an unnecessary looping assignment to a simple assignment suggested by
Maksym.

Added fixes and tweaks suggested by Maksym Veremeyenko [verem@m1stereo.tv] and
Clément B.

478455d66b ac3enc: initialize all coefficients to zero. 
Uninitialized coefficients were being used to generate exponents, some
of which actually ended up in the final stream.  Even though, they were
just extra exponents that are not used by any decoder, it is still
better to have consistent output for testing. This also fixes valgrind
errors.

80068da3a0 avoptions: Return explicitly NAN or {0,0} if the option isn't found 
This actually matches what av_get_double did earlier, the
0.0/0.0 division was intentional, for producing NAN.

Still keeping the check for the return value from
av_get_number, for clarity.

271c869cc3 rtmp: Don't try to do av_malloc(0) 
Some received packets can have size 0. The return value from
av_malloc(0) may be NULL, which is ok if the size was 0. On
OS X, however, the returned pointer is non-null but leads to
crashes when trying to free it.
