LCMS: upgrade to 2.8
This CL upgrades LCMS from version 2.6 to 2.8. All changes from LCMS original version 2.8 are stored in patch files: - Patch 0: memory management modifications to use PDFium methods. This was previously not in any patch, so the changes were manually applied. - Patches 1-5: new patch files corresponding to old changes that can be seen in the history, but did not previously have patch files. - Patches 6-25: previous patches (patch numbers shifted by 6). The one for from16-to-8-overflow.patch was deleted as it was already upstream. Some patches did not apply cleanly so their .patch files were modified. - Patch 26: as I just moved files directly, unsupported characters were moved in unchanged, so I had to fix all of them: e with tilde and other characters were replaced to allow compilation on Windows. - Patch 27: Went over the code and re-applied changes that included comments clearly indicating this was Foxit. These changes are all already seen in the initial PDFium commit.
