0aded9484d Move dct and rdft definitions to separate files
This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

4538729afe Move sine windows to a separate file
These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

a45fbda994 Move ff_kbd_window_init() to a separate file
This function is not tightly coupled to mdct, and it's in the way
of making a fixed-point mdct implementation.

26f548bb59 fft: remove inline wrappers for function pointers

42cfb3835b Remove Sonic experimental audio codec
Since initially committed in 2004, this codec has only been touched
for maintenanance.  Functionally, it contains no novel ideas and
its intended audience is better served by existing mature codecs.

79414257e2 mathops: fix MULL() when the compiler does not inline the function.
If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

323e6fead0 ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.
This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.

36864ac354 aac_latm_dec: use aac context and aac m4ac
When decoding latm config, use the corresponding aac context and its
m4ac instead of using NULL and a local variable. This fixes decoding of
audio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), when
there is no extradata. This is the case when using the decoder with
gst-ffmpeg and a GStreamer mpegts demuxer.

ad9791e12b pthreads: Fix bug introduced with thread_safe_callbacks
For intra codecs, ff_thread_finish_setup() is called before decoding starts
automatically. However, get_buffer can only be used before it's called, so
adding this requirement broke frame threading for them. Fixed by moving the
call until after get_buffer is finished.
