Needed to properly export avpriv_* symbols.

Also include config.h so that HAVE_ALTIVEC will be defined.

Move vector_fmul() from DSPContext to AVFloatDSPContext.

This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.

And reimplement av_get_channel_layout_string() on top of it.

Makes valgrind happy.

Otherwise, setting string will try to free a random address.

Some demuxers set a timecode in the format or streams metadata. The
muxers now make use of this metadata instead of a duplicated private
option.

This makes possible transparent copy of the timecode when transmuxing
and transcoding.

-timecode option for MPEG1/2 codec is also renamed to -gop_timecode. The
global ffmpeg -timecode option will set it anyway so no option change
visible for the user.

The use of cyan is droped from the levels to avoid confusion
magenta/cyan/blue is used for muxer/codec/filter layer

Move AVPALETTE_SIZE and AVPALETTE_COUNT definition from
libavcodec/avcodec.h to libavutil/pixfmt.h.

The definition is more useful in libavutil, where it can be shared for
example by libavfilter and libswscale.

The errors need to be defined before including functions depending on
them. See av_size_mult() for instance. stddef.h is included for the
prototype of av_sterror (use of size_t).

The current SSE version is slower than the MMX version on Athlon64 and Sandy
Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.

Just like gcc 4.6 and later on ARM, gcc 4.8 on MIPS generates
inefficient code when a known-unaligned location is used as a
memory input operand.  This applies the same fix as has been
previously done to the ARM version of the code.

GCC actually handles unaligned accesses correctly in all cases
except, absurdly, 32-bit loads on mips64.  The remaining asm is
thus not needed, and removing it results in better code.
