as a -I flag anymore.

page/win was removed in https://codereview.chromium.org/13642009.

Absolutify paths to platform/mac/.

There's another WebFontCache.h in the webkit api, so I fixed all (2) includes
of that file in core/ manually, temporarily renamed it, ran my script, and
renamed it back.

Unconfuse ambiguous includes of FontCustomPlatformData.h.

On Mac, both platform/graphics/mac and platfrom/graphics/skia are on the
include search path, and both contain a file contained FontCustomPlatformData.h.
In different translation units, different versions of the .h file would be
picked up. (At link time, only platform/graphics/mac/FontCustomPlatformData.cpp
is used.)

As fix, be explicit about which one should be included and add a forwarding
header that picks the right one based on the OS.

Absolutify paths to platform/graphics/skia/.

Last one! (in core/ at least, and api stuff is blocked on "webkit" getting
renamed.)
