_cogl_shader_set_source_with_boilerplate and _cogl_shader_compile_real
have enough GL assumptions that it makes sense to push them into the
backend. Taken together their only callers are under driver/gl, so.

This basically reverts commit 54735dec, which tried to avoid the
GLib-defined types in favor the standard C ones. One exception to this
is the bool type, for which the commit introduces a new type CoglBool.
Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of `int`) are completely compatible with bool (size `char`).

In cogl use cogl-config.h and in clutter use clutter-build-config.h. We
can't use clutter-config.h in clutter because its already used and
installed.

When using a context with robustness, glGetError() may return
GL_CONTEXT_LOST at any time and this error doesn't get cleared until
the application calls glGetGraphicsResetStatus() . This means that our
error checking can't call glGetError() in a loop without checking for
that return value and returning in that case.
