Fix trac ticket #2566.

This makes it consistent with the msvc builds which automatically set
the DEP and ASLR flags by default.  There really is no good reason why
they shouldn't be set.

The fact that binutils does not set them on by default boggles the mind.

  jpeg2000dec: don't use deprecated PIX_FMT values
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This replaces a large number of checks for the second field by
fixing the pointers when they are setup.

This should also fix I/BI field pictures.

Changes checksums for vc1_sa10143, the file becomes slightly closer
to what the reference decoder outputs.

Currently it would incorrectly trigger on a string that contains a '='
but does not contain a ':', e.g. flags=<flags>.

There is now no need to explicitly pass 0:0 as width/height to scale,
those are the defaults.
