mtklein 7fbfbbe8f4 Basic standalone GN configs.
This sketches out what a world without Chrome's GN configs would look like.

Instead of DEPSing in build/, we now host our own gypi_to_gn.py.

The symlink from skia/ to . lets us run gclient hooks when the .gclient file is in the directory above skia/ or inside skia/.  That means we don't need gn.py anymore.
