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.
