[FFmpeg-devel] [PATCH] all: s/Open/Allocate and initialize/ in comments

[Andrew Sayers]

Comments for a few prominent functions claim to "open" something, when they
actually "allocate and initialize" that thing.

Using a different word misleads users into thinking it's doing a different
thing, making the interface more time-consuming to learn.

Replace "open" with the more standard "allocate and initialize".
