Move pmgraph_t struct and functions to their own header file
This will allow us to utilize this helpful type and functions in places besides dependency calculations. In addition, remove the public declaration of pmgraph_t in alpm.h- there is zero need to expose this internal type. Signed-off-by: Dan McGee <dan@archlinux.org>
