If building out of tree, make sure the filter scripts are copied
into the build tree before running tests. This makes sure that
SRC_PATH doesn't need to exist on the remote system (or doesn't
need to exist at the same path).

Currently if no custom block VLC is specified for band, a default block VLC
will be used, while the global block VLC stored in the context should be used
instead.
This fixes decoding of one sample I have.
Now it can use different references for those blocks and even use
averaging.
This fixes several chroma artifacts in several videos.

Use the intensity-compensated reference frame for subsequent
fields/B-frames.
Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following
dependent frames.

This simplifies the code since copying MVs to the reference is not needed
anymore (and maybe something about fixing artifacts).
Also remove the unused mv_f_last.
Fixes a small number of artifacts in black_screen_VC-1.mkv
and several more artifacts in other videos.

Currently the demuxer shaves the blocks and exports only the
information that is useful to the decoder.
Exporting the blocks just as they are stored is simpler to understand
and will make remuxing wavpack easier.
Number of samples in the first block is checked to be strictly positive
earlier in wavpack_decode_frame() and number of samples in all the other
blocks is checked to be equal to the first one.
This matches the other eabi attribute in the same file. This is
required in order to build for arm/hardfloat with other object
file formats than ELF.

Initial support for the ICL compiler on windows. Requires a new
c99wrap with ICL support (1.0.2+).
Currently not much different speed wise compared to msvc. In the
future with a few changes it can be made to support the inline asm.
This would be the primary reason for using it.
Passed all fate tests, versions tested:
13.1.1.171 (2013 Update 3) x86 and x64
12.1.5.344 (2011 Update 11) x86 and x64

Change the check_exec_crash test to use a function pointer instead of
simply calling the function. The EBP availability test will crash when
compiled with ICL likely due to compiler optimization shenanigans.
Originally the check_exec_crash code was moved out of main to fix a
problem with gcc's treatment of non-leaf main on x86_32. Libav already
moved the code out of main but the addition of the function pointer will
prevent any inlining which fixes the remaining problem.
A function pointer is used since it is compiler agnostic (as opposed to
say __attribute__ ((noinline)) which would only work with gcc compatible
compilers).
