0b4b2ad530 page-types: add feature for walking process address space 
Introduce "-p|--pid <pid>" for walking the process address space.  The
default action is to walk raw memory PFNs.

Both the virtual address and physical address of each present pages will
be listed:

	# ./tools/vm/page-types -lp $$ | head -3
	voffset offset  len     flags
	400     11bebe  1       __RU_lA____M______________________
	402     11bebc  1       __RU_lA____M______________________

Note that voffset/offset/len are now showed as hex numbers.

35efa5e993 pagemap: add page-types tool 
Add page-types, a handy tool for querying page flags.

It will expand some of the overloaded flags:
	PG_slob_free   = PG_private
	PG_slub_frozen = PG_active
	PG_slub_debug  = PG_error
	PG_readahead   = PG_reclaim

and mask out obscure flags except in -raw mode:
	PG_reserved
	PG_mlocked
	PG_mappedtodisk
	PG_private
	PG_private_2
	PG_owner_priv_1
	PG_arch_1
	PG_uncached
	PG_compound* for non hugeTLB pages
