cd52ec95bb configure: remove filter_cppflags 
This is not used and the current design would not work properly
if mixing tools needing different filters.

07e3f9af9f configure: set icc_version where it is needed 
This variable is only used once, so setting it there is clearer.

4c9080a7ef lavfi: unref AVFilterLink.out_buf in ff_end_frame(). 
This reduces code duplication and prevents stale pointers from remaining
on the link.

07bad27810 lavfi: unref AVFilterLink.cur_buf in ff_end_frame().

5b50ae94e6 vf_slicify: clear AVFilterLink.cur_buf in start_frame(). 
The buffer is passed on to the next filter, so we shouldn't keep any
pointers to it.

0393af4f0b vf_settb: simplify start_frame(). 
Avoid pointless filter ref/unref. Just use the reference passed to
start_frame().

7155763b78 vf_drawtext: don't give up its own reference to the input buffer. 
Directly forwarding the input buffer to the next filter means that
drawtext no longer owns any references to it and thus shouldn't refer to
it in any way.

1749e12f45 cafdec: allow larger ALAC magic cookie 
It already skips any extra bytes at the end, and apparently there are some
samples in the wild with larger 'kuki' chunks.
