If you fix 1715 and it requires bumping ABI (which almost certainly it would)
then iam ok with bumping ABI (with a patch for review first)
But note the code that would fix 1715 is not in place, simply bumping the
ABI isnt going to fix it
you would have to get rid of
grep MAX_STREAMS libav*/*.h
(it can stay in the tools ff*.c for now it also can stay in cases
where its not part of the public ABI though some of that we might
want to fix too and some we might just want to handle by bumping
the constant up. Its the public ABI from where it must be removed)

new APIs are enabled in general old are under #if
besides if we do bump ABI i think --disable-avfilter should be droped too
at that time with the old cruft, the broken -crop* options and whatever else
is connected to it only
