* src/packdump.c:

* src/packdump.c:
   + (pobj_flag_dump, flag_bit_names):  Do hex & symbolic display of
     object flags.  Needs better abstraction, though.
   + (PackFile_Constant_dump):  Use pobj_flag_dump for strings, keys,
     and PMCs.  Dump closures as subs.  Add a missing "'" to the PFC_KEY
     output.  Remove bogus slice_bits update; this var is unused, and
     appears to have been causing stuff to be printed inappropriately.
* include/parrot/pobj.h:
   + (enum PObj_enum):  Add a doc ref to flag_bit_names.
