Fix configure problem with out-of-source-tree build for fate-related .mak files in the tests and tests/fate subdirectories

This patch will add to the list of files for which configure creates
symbolic links when building outside of the ffmpeg source tree.
This fixes a problem for fate-related .mak files in the tests and tests/fate
subdirectories.

This is necessary because some programs writing TGA files forget
to initialize parts of the header they don't care about, resulting
in "random" data there.
The new behaviour is consistent with other programs, e.g. tgatoppm.

In commit bebe72f4, the enum AV_PICTURE_TYPE_* was introduced. There are still places in the code where pict_type is used as an integer and there is a case where "pict_type = 0" with the explanation "let ffmpeg decide what to do". The new enum does not know a value of 0 and C++ will fail if compiling such programs anyway as it is refered as an int (and you cannot patch them properly).

This was done to support gcc 2.95, which is an old legacy compiler
that fails to compile the current codebase anyway.

Choose band type (codebook) zero, count its bits, and mark the other
states as unnavigable.

Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

This works through some non-obvious hacks in utils.c.

This is part of the Great Evil Plan to simplify swscale.

This will likely lead to a considerable performance boost,
since it removes a branch from the inner loop. Part of the

This prevents a crash when converting to NV12/21 without the bitexact
flags enabled.

This avoids using function pointers for quite a few small functions, most of
which just call DSP functions.

They introduce too much complexity for very little benefit. The result is that
encoding will be more likely to fail at extremely low bitrates where quality
would be awful anyway.

The previous code was erroneously assuming that the linesize was
equivalent to width*pixel_step, which is not always true.
