This removes the XP compatibility code, and switches entirely to SWR
locks, which are available starting at Windows Vista.

This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.

Windows XP is hereby not a supported build target anymore. It was
decided in a project vote that this is OK.

It should not be needed for each filter that sets sample aspect ratio
to set it explicitly also for each and every frame, instead that is
automatically done in get_buffer call.

Also, do not overread input if linesize > width, or linesize is not divisible
by 8, and use the proper rounded width/height for MAFD calculation.

This speeds up the filter, and also fixes scene change detection score which is
reduced based on the difference of the current MAFD to the preivous MAFD.
Obviously if we compare two frames twice, the difference will be 0...

- normalize score to [0..100] instead of [0..85]
- change the default score to 8.2 to roughly keep existing behaviour
- take into account bit depth
- do not truncate to integer

If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.

Added option allows users to select between replacement and composition.
Tested and documented.

'threshhold' should be 'threshold'
