a786c8259d idct: Split off Xvid IDCT
The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.

060e4a9e06 dct/rdft: Remove duplicate typedefs for context structs
The typedefs also exist in the avfft.h header and since typedefs cannot be
legally redefined in C, the code fails to compile with some compilers.

This reverts commits 11c7155cce and 57f1b1dcc7.

16e6652286 aarch64: NEON intrinsics dct_unquantize_h263.
Intrinsics only used on aarch64 since the existing ARMv7 NEON asm
is slightly faster (Cortex-A9, gcc-4.8, micro-benchmarks and full
decoding time).
