Robert Bragg 0e7a632e13 Adds initial Emscripten support to Cogl
This enables basic Emscripten support in Cogl via the SDL winsys.
Assuming you have setup an emscripten toolchain you can configure Cogl
like this:

 emconfigure ./configure --enable-debug --enable-emscripten

Building the examples will build .html files that can be loaded directly
by a WebGL enabled browser.

Note: at this point the emscripten support has just barely been smoke
tested so it's expected that as we continue to build on this we will
learn about more things we need to change in Cogl to full support this
environment.
