Extract two methods from decode_registered_user_data in order to improve
code readability. Also make the constant holding the allocation size a
64-bit unsigned integer so that the size comparison against INT_MAX makes
sense.

This commit removes a redundant argument from the functions in aaccoder.
The argument lambda was redundant as it was just a copy of s->lambda,
to which all functions have access to anyway. This cleans up the function
pointers a bit which is helpful as there are a lot of other search_for_*
functions under development and with them populated it gets messy.

dxva2/d3d11va: Set _WIN32_WINNT to 0x0602 instead of 0x0600
Merged-by: Michael Niedermayer <michael@niedermayer.cc>
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.

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).

When skip_frame is set to _NONKEY the decoder skips everything except intra
slices, which breaks frames that consist of an intra field together with any
other field type; half the frame becomes garbage. This patch fixes the issue by
letting non-intra slices through if they're part of a keyframe.
