Removed previous swscale code under '#ifndef NEW_FILTER'
and removed unused fields of SwsContext

There are no known users of these functions within debian
It should be thus possible to remove these functions without recommandition of a
replacement

The relocation hack broke debugging on mingw-w64 when using gdb.  This
makes the reloc hack dependent on --disable-debug so it's still enabled
for release builds.

This is simply an immediate fix for the issue of broken debugging, we
should probably still look at the possibility of reverting it outright
if it proves to be more trouble than it's worth.  For now keeping it
enabled for release builds is a reasonable trade off.

Clamp scalefactors by coef2minsf to avoid undefined behavior
caused by signed integer overflow. It also avoids clipping of
coefficients so it should avoid artifacts as well, on very
rare corner cases.

This avoids unneeded computations

Remove false claim that processing in freq domain is
worse quality than processing in time domain.

This reverts commit c0918613, since it
triggered a new assertion with gcc.
This bug definitely needs a true proper fix.

This reverts commit bf1495d9.

Seems like clang might be miscompiling it and causing a signed integer overflow,
making a FATE test fail.
Doesn't seem to affect performance, it only runs on the ESC codebook.
