conntrackd: generalize/cleanup network message building/parsing

This patch generalizes the network message building and parsing
to prepare the upcoming expectation support.

Basically, it renames:

- NET_T_STATE_* by NET_T_STATE_CT_*, as I plan to add NET_T_STATE_EXP_*
- BUILD_NETMSG by BUILD_NETMSG_FROM_CT, and build_payload by ct2msg.
  I plan to add exp2msg.
- parse_payload by msg2ct, since I plan to add msg2exp.
- modify object_status_to_network_type to prepare the support of
  expectations.
- add prefix ct_ to all parsing functions in parse.c, as we will have
  similar functions to convert messages to expectation objects.
