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.

cf9c227e58 ARM: fix vp8 neon with pic enabled 
The assembler emits literal pools too far from the load instructions,

451b4b8635 Rearrange MpegEncContext to simplify access from asm 
This moves the fields needed by asm near the top, before any
structs or other members which complicate the offset calculation.
Modifying other structs will no longer require updating the offsets,
and the asm code is slightly simpler due to the smaller offsets.

4a384de5b8 Split h264dsp and h264pred in configure. 
Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions
but not the weight/loopfilter functions.
This should reduce the size of builds with one of these derivatives but without
H.264 decoding itself.
