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.

This is required if we return other error codes than explicitly
-1, which so far has been the only other possible return value
besides 0.

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.

Based on "vc1dec: the second field is written wrong to the picture"
by Sebastian Sandberg <sebastiand.sandberg@gmail.com>.

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.

This was due to a miscomputation of s->cur_channel, which led to
psy-based encoders using the psy coefficients for the wrong channel.

This fixes a case where multichannel bitrate isn't accurately
targetted by psy model alone, never achieving the target bitrate.

The C code treats the data as arrays of uint16_t so strides must not
be in bytes but in pixels.

Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed3976 slowed the filter to just under 3/4 of what it
was.  This commit restores the speed while maintaining identical output.
