2c5c37ade1 libswresample: move condition to start of loop. 
This avoids several issue like calculating sum/maxcoef
incorrectly due to adding up matrix entries that will
be overwritten, as well as out-of-range writes to
s->matrix if the maximum allowed number of channels is used.

2231d5b671 libswresample: Avoid needlessly large on-stack array. 
We only actually need to use a tiny part of it.
Unfortunately we seem to have no real test coverage on
the code, so this is a bit risky.

include resample_template.c
