In particular, fix wrong vertical mirroring command, and clarify

Based on a patch by littlebat <dashing.meng@gmail.com>.

Should fix trac ticket #2413.

The same message is shown already by the called function
ff_bufqueue_is_full().

In the aspect filter most changes are merged but not the final
switch to the libav API because that is too restrictive and has
difficulty handling the syntax.

This expression is useful to enable/disable overlaying on the fly.

Note that this can't be easily done relying on the filtergraph structure,
since this implies caching issues or a null frame overlaying in the best
case, which is better avoided for performance and convenience reasons.

Add support for dynamic x, y expressions evaluation.

Also add support for an evaluation mode which allows to disable per-frame
evaluation, so that there is no speedloss in case the expression does not
depend on frame variables.

The new name is more semantically and stilistically consistent.
