Saves a pointless free/alloc cycle on reinit. For the vast majority of filter
links, this going to be allocated anyway; and on the occasions that it's not,
the waste is marginal.

This struct is overally pretty trivial and there is little to no internal
state or invariants that need to be protected.
Making it public allows e.g. libswscale to allocate buffers for individual
planes directly.

This helper is of dubious utility - it was only used to reinitialize the
frame pools, which is better handled by `ff_frame_pool_reinit()`, and at
present only serves to make extending the API harder.
Users who really need to randomly query the state of the frame pool can
already keep track of the values they set.

This moves the check-uninit-reinit logic out of audio.c/video.c and into
framepool.c, where it can be more conveniently re-used by future users.
