This avoids false positive enabling of w32threads if explicitly
requested on the command line, but dependencies are missing.

Intensity compensation is always used once it was encountered, because
v->next_use_ic is never set back to zero.

Reset v->next_use_ic, when resetting v->next_luty/uv.

Also fix the #endif comment in a few places and #include config.h to
avoid assuming it is #included implicitly.

The RGB32 pixel format is RGBA/BGRA depending on target
endianness - make sure to convert it to one specific format for
the framecrc tests.

This fixes the pngparser fate test on big endian.

Additional editing by Diego Biurrun

Since pc.state is populated by shifting in from the end of the
32 bit word, the content within pc.state is already in native endian
and should not be read with the AV_R{L,B} functions.

This was already done correctly for state64 above.

This fixes the fate-corepng test on big endian.
