4e781c25b7 graphparser: fix the order of connecting unlabeled links.
Right now, e.g. scale,[in]overlay would connect scale to the first
overlay input and [in] to the second, which goes against the
documentation and is unintuitive.

The bug happens because of the ordering mess in curr_inputs variable:
1) the unlabeled links from the previous filter are added to it in
correct order
2) input labels are parsed and inserted to the beginning one by one
(i.e. in reverse order)
3) curr_inputs is matched against filter inputs in reverse order

Fix the problem by always using proper ordering without trying to be
clever.

6458a08700 vf_scale: ensure the palette is set for output.
Since those are pseudo-palette formats, swscale does not write
into data[1], swscale must initialize the palette properly itself.
This lead to frames that actually decoded as all-gray before.

This fixes that the GIF encoder crashes with it because

And the arguments for the pseudopalette apply to gray8 as
much as to RGB8 etc.

Current code, with a filterchain such as

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

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.

8ec0832743 drawutils: new API.
This new API stores useful data in a dedicated structure
and has clearly delimited init functions.

Hopefully, uses of the old API can be replaced quickly.

c9399538b7 lavfi/ass: use a default DAR value of 1.0
Previously it was using the same value of the input video DAR, which is
inconsistent with most implementations.

Fix trac ticket #1098.

e71e65ff1d lavfi/aspect: check for a negative code from av_parse_ratio()
Check on < 0 rather than on != 0, this is more correct as a positive
error code from av_parse_ratio() value doesn't mean an error.

The current version relied on poll_frame to request
the very first frame, that would not work if the
