[bgpd] cleanup, compact and consolidate capability parsing code
2007-07-26 Paul Jakma <paul.jakma@sun.com>
* (general) Clean up and compact capability parsing slightly.
Consolidate validation of length and logging of generic TLV, and
memcpy of capability data, thus removing such from cap specifc
code (not always present or correct).
* bgp_open.h: Add structures for the generic capability TLV header
and for the data formats of the various specific capabilities we
support. Hence remove the badly named, or else misdefined, struct
capability.
* bgp_open.c: (bgp_capability_vty_out) Use struct capability_mp_data.
Do the length checks *before* memcpy()'ing based on that length
(stored capability - should have been validated anyway on input,
but..).
(bgp_afi_safi_valid_indices) new function to validate (afi,safi)
which is about to be used as index into arrays, consolidates
several instances of same, at least one of which appeared to be
incomplete..
(bgp_capability_mp) Much condensed.
(bgp_capability_orf_entry) New, process one ORF entry
(bgp_capability_orf) Condensed. Fixed to process all ORF entries.
(bgp_capability_restart) Condensed, and fixed to use a
cap-specific type, rather than abusing capability_mp.
(struct message capcode_str) added to aid generic logging.
(size_t cap_minsizes[]) added to aid generic validation of
capability length field.
(bgp_capability_parse) Generic logging and validation of TLV
consolidated here. Code compacted as much as possible.
* bgp_packet.c: (bgp_open_receive) Capability parsers now use
streams, so no more need here to manually fudge the input stream
getp.
(bgp_capability_msg_parse) use struct capability_mp_data. Validate
lengths /before/ memcpy. Use bgp_afi_safi_valid_indices.
(bgp_capability_receive) Exported for use by test harness.
* bgp_vty.c: (bgp_show_summary) fix conversion warning
(bgp_show_peer) ditto
* bgp_debug.h: Fix storage 'extern' after type 'const'.
* lib/log.c: (mes_lookup) warning about code not being in
same-number array slot should be debug, not warning. E.g. BGP
has several discontigious number spaces, allocating from
different parts of a space is not uncommon (e.g. IANA
assigned versus vendor-assigned code points in some number
space).

bgpd: Add Long-lived Graceful Restart capability (restarter)
Restart Router mode.
FRRouting (Restarter):
```
bgp long-lived-graceful-restart stale-time 10
bgp graceful-restart restart-time 1
```
Tested with GoBGP (Helper):
```
long-lived-graceful-restart: advertised and received
Local:
ipv4-unicast, restart time 100000 sec
Remote:
ipv4-unicast, restart time 10 sec, forward flag set
```
Logs:
