Fixes some files from Ticket679

This also changes subtitles to 4:2:0 matching the output format and thus
simplifying the blend code.
This restricts placement to the chroma sample resolution though, speak up
if you consider this a problem, say so, the code could be changed to use
YUV444 for subtitles and scaling them down while blending, this would be
slower though.
The current code only uses a single swscale context and reinitializes it
as needed, this could be changed as well if needed

This commit replaces the 1 microsecond delay by 500 microsecond for the
case when the MFX library does return MFX_WRN_DEVICE_BUSY status.
In general this warning never appears for simple encoding or
transcoding session because the GPU is so fast so it almost always is not busy and
any delay value just does not executes.
But for heavy transcoding tasks for example, when several QSV sessions
are running simultaneously then using a 1-microsecond delay may
result in 1000 iterations per each frame.
So here possible a paradoxical case when GPU loading also loads CPU by dummy tasks.
Official MFX/QSV samples by Intel are using 1 millisecond (i.e. 1000
microseconds) everywhere where MFX_WRN_DEVICE_BUSY does appear.
So 500us is a much more optimal value than 1us.

There was fixed number of loops (2048) in preparation for resampler, so
when number of samples is smaller than this, there would be an overflow on
ret_buf.

For some reason this behavior popped out only under valgrind with
--disable-memory-poisoning option.

This is now fixed and number of loops depends on actual number of samples.

This avoids having to manually set _WIN32_WINNT in --extra-cflags
when targeting these API families, which only was necessary to
work around configure setting _WIN32_WINNT to an older version
by default.

If _WIN32_WINNT is unset, we force it to a new enough value to
make sure the necessary definitions are visible.

When targeting Windows Phone or Windows RT, _WIN32_WINNT should
be at least 0x0602 - otherwise the windows headers themselves
can cause errors (which technically are bugs in the headers).

Raising this value here shouldn't hurt; the alternative would
be to not touch it at all if WINAPI_FAMILY is set to phone/app,
or to force setting it to 0x0602 in configure if unset (for phone/app).
