Preserve forwarding state bit can be set in OPEN message with the use of
new vty commands
bgp graceful-restart preserve-fw-state
no bgp graceful-restart preserve-fw-state
This must be set before activating the connection to a peer, since it is
for forging graceful restart capability of OPEN messages.

Enhance struct bgp to add a new flag BGP_FLAG_GR_PRESERVE_FWD, which
allow to set the Preserve State F bit of Graceful Restart capability in
OPEN messages.

* lib/if.h: Remove LP_TE as Link Parameters is set if different from 0
See IS_LINK_PARAMS_SET macro and use LP_TE_METRIC to determine if TE metric
is set or not
* lib/if.c: replace LP_TE by LP_TE_METRIC in default LP status
* zebra/interface.c: replace LP_TE by LP_TE_METRIC and check if TE metric
is equal to standard metric or not
* ospfd/ospf_te.c: replace LP_TE by LP_TE_METRIC
* isisd/isis_te.c: replace LP_TE by LP_TE_METRIC

After graceful restart procedure, when BGP speaker has finished to send
its VPNv4 routes to the restarting peer, it also sends End-Of-Rib
message for afi=AFI_IPv4 safi=SAFI_MPLS_VPN.

This patch enable the support of graceful restart for routes sets with
vpnv4 address family format. In this specific case, data model is
slightly different and some additional processing must be done when
accessing bgp tables and nodes.
The clearing stale algorithm takes into account the specificity where
the 2 node level for MPLS has to be reached.

Because SAFI_RESERVED_3 value is no more used, the SAFI_MPLS value is
lowered to that value.

Update the ZEBRA_HEADER_MARKER to 254. This will differentiate
ourselves from Quagga. Zebra should not listen to people not
properly using the right programs now.
Update the ZAPI version number to 4.

Commit 43cc09d has been shown to cause several issues with clients
connecting.
Partial revert, since I wanted to keep the debug logs added
for that commit, as well remove the piece of code that
stops attempting to connect to zebra. If we've failed
a bunch of times, there is nothing wrong with continuing
to do so once every 60 seconds. I've debug guarded
the connect failure for those people running bgp
without zebra.

- "redist foo" parsing modified to check for foo==vnc and foo==vnc-direct
instead of just leading 'v' character
- string designating ZEBRA_ROUTE_VNC_DIRECT changed from "vpn" to "vnc-direct"
- route_types.pl parser recognizes 7th field to restrict availability
of a route type in the redist command to specific daemons
- restrict "vnc-direct" to bgpd only (doesn't make sense elsewhere)
- vnc documentation updated to match

It looks like 'nexthop_fib_num' has been lingering around since 2003
without any use. Remove it.

On *BSD, we update a route in the FIB by removing the old one and then
installing the new version.
With that said, on kernel_route_rib() we need to provide a pointer to
both the old version and the new version of the route.
We were, however, passing a pointer to the new version to both the
'old' and 'new' parameters. This is not a problem on Linux, which uses
NLM_F_REPLACE to update routes, but it breaks route updates on *BSD
because the 'old' parameter points to a route that is not installed in
the kernel. The kernel_route_rib() function then fails to uninstall the
supposedly 'old' route and can fail to install the new version as well if
the kernel doesn't support ECMP (e.g. FreeBSD with default configuration).

This makes the actual change to the manpages to get ./configure effects
applied into them.
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
The manpages contain references to installation paths and thus should be
preprocessed by ./configure to get the actual paths.
This commit is an exact-rename so the changes for the preprocessing are
easier to review (diffs in renames are hard to read...)
