Upgrade OpenJPEG to 2.2.0
This CL upgrades OpenJPEG by copying the files from 2.2.0 and then applying patches. Patch files that are no longer relevant are deleted. The relevant ones are applied manually due to changes in formatting in OpenJPEG. Patch 34 is added to account for opj_malloc changes in PDFium. Bug: chromium:718731 Change-Id: I3d316893eab5e235c9f71222a6818b8ae0c98383 Reviewed-on: https://pdfium-review.googlesource.com/12770 Commit-Queue: dsinclair <dsinclair@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org>
