82e5f86bd5 Implement shuffle_bytes_abcd() functions and use them for shuffling
bytes when converting between RGB32 variants.

In particular fix the argb -> rgba and abgr -> bgra conversions.

See the thread:
Subject: [FFmpeg-devel] [RFC] RGB32 / BGR32 ethernal bug

af0e662169 Declare support for the pixel formats:
PIX_FMT_YUVJ420P
PIX_FMT_YUVJ422P
PIX_FMT_YUVJ440P
PIX_FMT_YUVJ444P

in the isSupported{In,Out} macros.

These pixel formats are not true pixel formats but hacks specific to
JPEG in libavcodec. They are deprecated and should be removed (that is
from libavcodec first and libswscale second)...  but they must be
tested by swscale-test.

SwsContext:srcFormatBpp and SwsContext:dstFormatBpp fields, and remove
