e36b25d1df vf_overlay: implement poll_frame() 
Signal that it can output a frame when there are frames on the main
input and EOF on the overlay input, but a frame is buffered -- e.g.
single picture overlay.

1f068e4450 vf_unsharp: Mark readonly variable as const. 
This fixes the following warning:

416fd90ead vf_scale: avoid a pointless memcpy in no-op conversion. 
I.e. just pass the buffer along when src parameters == dst parameters.

63736fe48c avfiltergraph: try to reduce format conversions in filters. 
Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.

This commit attempts to improve in the following way:
repeat until convergence:
  loop over all filters
    find input link with exactly one format
    force this format on all output links of the same type (if possible)

e7e19b15c7 build: Only clean the architecture subdirectory we build for. 
This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

e496c45d9b drawtext: add 'fix_bounds' option on coords fixing 
Before, drawtext filter deliberately altered given text coordinates if
text didn't fully fit on the picture. This breaks the use case of
scrolling large text, e.g. movie closing credits.
Add 'fix_bounds', to make it usable in such cases (by setting its value to 0).
Default behavior is not changed, and non-fitting text coords are fixed.

b58dbb5b03 lavc: add a sample_aspect_ratio field to AVFrame 
The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

cc276c85d1 Make channel layout masks unsigned 
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.
