[FFmpeg-devel] [PATCH] Add support for libopenjpeg 2.3

[Gyan Doshi]

OpenJPEG 2.3 was released a few days ago. Changelog reports "No API/ABI 
break compared to v2.2.0 but additional symbols for subset of components 
decoding"

This patch is adapted from an earlier patch which added support for 2.2.

Applied and tested locally.
