Implementation of a GL-virtualization layer for Skia. This allows for
environments using skia to specify a GL implementation at run-time, instead of
relying on the linker to pull in the appropriate GL impl.
A new structure, GrGLInterface is exposed. This struct contains a set of
function pointers that should point to an appropriate GL implementation.
This change also removes the reliance on GLew on windows builds.

+/**
+ * We need to pull in the right GL headers and determine whether we are
+ * compiling for ES1, ES2, or desktop GL. (We allow ES1 and ES2 to both be
+ * supported in the same build but not ESx and desktop). We also need to know
+ * the platform-specific way to get extension function pointers (e.g.
+ * eglGetProcAddress). The port specifies this info explicitly or we will infer
+ * it from the GR_*_BUILD flag.
+ *
+ * To specify GL setup directly define GR_GL_CUSTOM_SETUP to 1 and define:
+ * GR_SUPPORT_GLDESKTOP or (GR_SUPPORT_GLES1 and/or GR_SUPPORT_GLES2) to 1
+ *
+ * if GR_SUPPORT_GLDESKTOP is 1 then provide:
+ * 1. The name of your GL header in GR_INCLUDE_GLDESKTOP
+ * 2. If necessary, the name of a file that includes extension
+ * definitions in GR_INCLUDE_GLDESKTOPext.
+ * if GR_SUPPORT_GLES1 is 1 then provide:
+ * 1. The name of your GL header in GR_INCLUDE_GLES1
+ * 2. If necessary, the name of a file that includes extension
+ * definitions in GR_INCLUDE_GLES1ext.
+ * if GR_SUPPORT_GLES2 is 1 then provide:
+ * 1. The name of your GL header in GR_INCLUDE_GLES2
+ * 2. If necessary, the name of a file that includes extension
+ * definitions in GR_INCLUDE_GLES2ext.
+ *
+ * Optionally, define GR_GL_FUNC to any qualifier needed on GL function
+ * pointer declarations (e.g. __stdcall).
+ *
+ * Define GR_GL_PROC_ADDRESS to take a gl function and produce a
+ * function pointer. Two examples:
+ * 1. Your platform doesn't require a proc address function, just take
+ * the address of the function:
+ * #define GR_GL_PROC_ADDRESS(X) &X
+ * 2. Your platform uses eglGetProcAddress:
+ * #define GR_GL_PROC_ADDRESS eglGetProcAddress(#X)
+ *
+ * Optionally define GR_GL_PROC_ADDRESS_HEADER to include any additional
+ * header necessary to use GR_GL_PROC_ADDRESS (e.g. <EGL/egl.h>)
+ *
+ * Alternatively, define GR_GL_CUSTOM_SETUP_HEADER (and not GR_GL_CUSTOM_SETUP)
+ * to a header that can be included. This file should:
+ * 1. Define the approprate GR_SUPPORT_GL* macro(s) to 1
+ * 2. Includes all necessary GL headers.
+ * 3. Optionally define GR_GL_FUNC.
+ * 4. Define GR_GL_PROC_ADDRESS.
+ * 5. Optionally define GR_GL_PROC_ADDRESS_HEADER
