Prepare the ground for allowing temporary aspath object living on the stack.

To do this path_copy() gets a second argument (dst, src) and a new function
path_prep() is introduced to initialize an aspath object. The current
path_copy() usage is replaced with path_copy(path_get(), asp) which does
the same. Additionally some const where added to the *_copy functions to
make it more obvious which is the source and target. Also the pftable_ref()
and rtlabel_ref() functions return now the id instead of void.
