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.
