Update Android FreeType version.

Update Android FreeType version.

Update FreeType to a newer version. Because this caused issues in
finding the correct ftoptions.h and ftmodule.h [1], be sure to state
the ones we want explicitly.

This also add gzip.c which is needed for WOFF support [2].

[1] FreeType "Simplify header file hierarchy."

[2] FreeType "[gzip] New function `FT_Gzip_Uncompress'."

This works at PS2, but the change in FreeType is obviously subtly changing a
large number of baselines. (These can be seen with
gm/rebaseline_server/server.py --rietveld-issue 833103004 .) Not sure if I want
to submit right now due to the rebaseline load, but this is a probably needed
change.

Now that we can see what's going to change again, let's update our version of
FreeType. Note that this probably affects all the gms which use FreeType for
masks, due to some bug fixes in the hinting code, but there are now only ~20 of
those.

This updates us to the most recent commit into freetype, but the commit
description implies that this is android specific.  Does either Chrome or the
Android OS have plans to use this recent version of FreeType?

so this file is no longer needed?

Chrome for Android is currently on 2.6.1+1 and will need to be updated again
soon. I think Android is currently on 2.6.0 and will need to be updated at some
point as well (they've made it very difficult to update). ChromeOS just made it
to 2.6.1+1 I believe, but they're also going to want to update soon. If it
doesn't happen soon, I'll ask for a FreeType 2.6.2 release for the bugfixes
before anything else big goes in. Currently, we're way behind both Android and
Chrome for Android.

Almost all of what's in this update over 2.6.1 is bugfixes in response to
fuzzing. Part of the reason for this is for us to roll early to see if there are
any rendering regressions.

It got renamed to ftfntfmt.c, so I'm just updating the name here.

lgtm.  Can you file a buganizer bug against Android to track updating their copy
of FreeType?
