6c1c6c6c71 avfilter/drawtext - implement fix_bounds
When enabled, text, including effects like shadow or box, will be
completely bound within the video frame.

Default value changed to false to keep continuity of behaviour.

Fixes #6960.

183ce55b0d lavfi: split frame_count between input and output.
AVFilterLink.frame_count is supposed to count the number of frames
that were passed on the link, but with min_samples, that number is
not always the same for the source and destination filters.
With the addition of a FIFO on the link, the difference will become
more significant.

Split the variable in two: frame_count_in counts the number of
frames that entered the link, frame_count_out counts the number
of frames that were sent to the destination filter.

7c8fcbbde3 avutil/tree: add additional const qualifier to the comparator
libc's qsort comparator has a const qualifier on both arguments. This
adds a missing const qualifier to exactly match the comparator API.

Existing usages of av_tree_find, av_tree_insert are appropriately
modified: type signature changes of the comparators, and removal of
unnecessary void * casts of function pointers.
