libctf: fixes for systems on which sizeof (void *) > sizeof (long)

Browse Source 
Systems like mingw64 have pointers that can only be represented by 'long
long'.  Consistently cast integers stored in pointers through uintptr_t
to cater for this.

libctf/
	* ctf-create.c (ctf_dtd_insert): Add uintptr_t casts.
	(ctf_dtd_delete): Likewise.
	(ctf_dtd_lookup): Likewise.
	(ctf_rollback): Likewise.
	* ctf-hash.c (ctf_hash_lookup_type): Likewise.
	* ctf-types.c (ctf_lookup_by_rawhash): Likewise.
