framework/profile: add a copy method to profile

This will allow a profile to be copied and "subclassed" without
affecting the original profile. This will allow a long-standing bug that
made it impossible to run two subclasses of all.py (say shader.py and
glslparser.py) at the same time, since they would both try to modify the
all.py profile in incompatible ways.
