05aec7bb87 Separate DWT from snow and dsputil
This moves the DWT functions from snow.c and dsputil.c to a file of
their own.  A new struct, DWTContext, holds the function pointers
previously part of DSPContext.

cc1e807f4c snow: remove unused stub functions
w53_32_c() and w97_32_c() are defined as stubs when snow encoder is
disabled.  In this case, those functions are not referenced at all
and do thus not need to be defined.

b250f9c66d Change semantic of CONFIG_*, HAVE_* and ARCH_*.
They are now always defined to either 0 or 1.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

d593e32983 use 16bit IDWT (a SIMD implementation of it should be >2x faster then with
the old 32bit code)
disable mmx/sse2 optimizations as they need a rewrite now

ce611a27be Change rounding of the horizontal DWT to match the vertical one.
This allows some simplifications and optimizations and should
not have any effect on quality.

059715a41c First part of a series of speed-enchancing patches.
This one sets up a snow.h and makes snow use the dsputil function pointer
framework to access the three functions that will be implemented in asm
in the other parts of the patchset.
