gpg: Extend free_packet to handle a packet parser context.

* g10/packet.h (struct parse_packet_ctx_s): Add fields LAST_PKT and
FREE_LAST_PKT.
(init_parse_packet): Clear them.
(deinit_parse_packet): New macro.  Change all users if
init_parse_packet to also call this macro.
* g10/free-packet.c (free_packet): Add arg PARSECTX and handle shallow
packet copies in the context.  Change all callers.
* g10/parse-packet.c (parse): Store certain packets in the parse
context.
