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.

42655b24c2 avfiltergraph: avoid harmful auto audio conversions. 
With the current code, an automatically inserted aconvert necessary
for format change would usually convert to mono for no good reason.

The new code will not avoid all conversions, but at least will keep
them among the layouts common to both filters.
