9f5ff83f2a PPC asm for AV_RL*() 
PPC is normally big endian but has special little endian load/store
instructions.  Using these avoids a separate byteswap.  This makes the
vorbis decoder about 5% faster.  Not much else uses little-endian
read/write extensively.

GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
a packed struct), so we override it with a plain pointer cast.

3c55ce039d ARM asm for AV_RN*() 
ARMv6 and later support unaligned loads and stores for single
word/halfword but not double/multiple.  GCC is ignorant of this and
will always use bytewise accesses for unaligned data.  Casting to an
int32_t pointer is dangerous since a load/store double or multiple
instruction might be used (this happens with some code in FFmpeg).
Implementing the AV_[RW]* macros with inline asm using only supported
instructions gives fast and safe unaligned accesses.  ARM RVCT does
the right thing with generic code.

This gives an overall speedup of up to 10%.

a6783b8961 Reorganise intreadwrite.h 
This changes intreadwrite.h to support per-arch implementations of the
various macros allowing us to take advantage of special instructions
or other properties the compiler does not know about.

6e08ca9c51 Make the pixel formats which were defined as macros: 
PIX_FMT_ARGB
PIX_FMT_RGBA
PIX_FMT_ABGR
PIX_FMT_BGRA

defined as enum PixelFormat values, and viceversa make:
PIX_FMT_RGB32
PIX_FMT_RGB32_1
PIX_FMT_BGR32
PIX_FMT_BGR32_1

defined as macros, also resort accordingly the enum PixelFormat
list.
Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
aliases, in order to make ffmpeg pass regressions test.

This change breaks ABI backward compatibility.
