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.
