LibGL: Implement glGenLists and a few friends

This commit implements glGenLists(), glNewList(), glDeleteLists(), and
glCallList().
The 'compiled' records are implemented as a vector of member function
pointers and tuples containing their arguments, and a mechanism is
implemented to allow the recorded calls to copy-capture values from the
time of the call; this is currently only used with glLoadMatrix.
