With complex filters, an output can come from any input,
or several inputs, including inputs of a different type.
Copying the codec parameters from the first input with
the same type does not make any sense.

This does not change anything for simple 1->1 filters,
as source_index is set in that case.

With complex filter graphs, it can end up accessed
without having been set.

This frame rate is more reliable than the one copied
from the input stream, so it is used in priority.

The arguments now use the key=value syntax.

The current flat arguments syntax is not easily extensible
due to sws_param possibly containing commas.
This is also consistent with abuffersrc.

This should fix the fate failure

Move vector_fmul() from DSPContext to AVFloatDSPContext.

This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.
