Move skia to DEPS, and put it in third_party.

This CL updates chrome to the latest version of skia, retrieved via DEPS, and
placed in third_party.  All relevant skia changes (for all 3 platforms) have
been upstreamed.

Most of this CL is mind-numbingly repetitive.  Things of interest are:  skia.gyp
(now points at third_party versions), DEPS, and SkUserConfig.h.  stdint.h:  Skia
now requires C99 integer types, which MSVC doesn't support natively.  I have put
typedefs in config/win/stdint.h.

Note that the new version of skia appears to render rects whose coordinates
are "backwards" (ie., x2 < x1 or y2 < y1), which were formerly culled.  There
were a couple obvious instances of this in the code which I fixed, but there may
be more.

There were ~35 layout test failures due to minor pixel differences which I
rebaselined on Windows and Linux, and 8 genuine failures related to masks and
stroked text, which I have put in text_expectations.txt and assigned to
myself.  (There was another change which broke ~1700 tests on each platform,
but I put that change behind an #ifdef for now).

This CL updates chrome to the latest version of skia, retrieved via DEPS, and
placed in third_party.  All relevant skia changes (for all 3 platforms) have
been upstreamed.

Most of this CL is mind-numbingly repetitive.  Things of interest are:  skia.gyp

now requires C99 integer types, which MSVC doesn't support natively.  I have put

I didn't remove the old version of skia from our directory in this CL, since gcl
chokes when I try to upload it.  I also didn't upload the 1694 layout tests
which will be rebaselined by this change, but I will commit them.  I ran
perceptualdiff on them, and they all passed (they're LSB differences).

Finally, there are some minor webkit changes required for this move, which can
be found in codereview.chromium.org/73047.  I can't submit these to webkit yet,
due to timing issues (if it goes in webkit before this CL goes in, it'll break
on the next merge, so I planned to commit them locally in this CL and upstream
afterwards.
