avutil/internal: remove FF_ALLOCx{_ARRAY}_OR_GOTO macros
These functions have a terrible design, let us fix them before extending
them.
First design mistake: no error code. A helper function for testing
memory allocation failure where AVERROR(ENOMEM) does not appear is
absurd.
Second design mistake: printing a message. Return the error code, let
the caller print the error message.
Third design mistake: hard-coded use of goto.
