Effectively we had encountered situations on system startup
where the interface speed for a device was not properly setup
when zebra learns about the interface ( Imagine a bond being
brought up and the controlling software creating the bond
is not fast given system load, the bond's speed changes
upwards for each interface added ).
The initial workup on this was to allow a 15 second window
and then just reread the interface speed. We've since noticed
that under heavy system load on startup this is not always sufficient.
So modify the code to wait the 15 seconds and then check the interfaces
speed. If the interfaces speed is still MAX_UINT32T or it has changed
let's wait a bit longer and try again.

tests: Topotests are not giving sufficient time to propagate data
A bunch of our current tests setup data and redistribute
it across some bgp connections and then test for it
being there. A delay of 2 seconds that was initially
there to ensure that the data has propagated does not
actually work all the time when you have a loaded
virtualized environment.
Make the sleep 10 seconds. I agree this is not the ideal
solution but I would rather get the damn tests up and running
again.

LDP opens two sockets to zebra, one through ldpd (always using
instance 0) and another through lde (using whatever instance
was set through the -n command line parameter). If no instance
was set, both connections would use the same protocol and instance,
making it impossible to distinguish them through zserv_find_client.
This meant that a response to a lm connect would erroneously go to
the wrong process. Fix this by having a default instance value of 1,
in case the user does not specify a different one.

in order to both streamline the code and allow users to
define their own specialized versions of the LM api handlers,
define hooks for the 4 main primitives offered by the label
manager (i.e. connect, disconnect, get_chunk and release_chunk),
and have the existing code be run in response to a hook_call.
Additionally, have the responses to the requesting daemon be
callable from an external API.
Note that the proxy version of the label manager was a source of
issues and hardly used in practice. With the new hooks, users with
more complex requirements can simply plug in their own code to
handle label distribution remotely, so there is no longer a reason
to maintain this code.

This is not part of the make check tests and it has been broken
for a while, apparently. The way the label manager is coded makes
it very hard to code unit tests, and testing the relay of requests
to an external label manager is probably better done through
a topotest, so remove this.

when requesting a specific label chunk (e.g. for the SRGB),
it might happen that we cannot get what we want. In this
event, we must be prepared to receive a response with no
label chunk. Without this fix, if the remote label manager
was not able to alloate the chunk we requested, we would
hang indefinitely trying to read data from the stream which
was not there.
Signed-off-by: Emanuele Di Pascale <emanuele@voltanet.io>
For SRGB, we need to support chunk requests starting at a
specific point in the label space, rather than just asking
for any sufficiently large chunk. To this purpose, we extend
the label manager api to request a chunk with a base value;
if the base is set to 0, the label manager will behave as it
currently does, i.e. fetching the first free chunk big enough
to satisfy the request.
update all the existing calls to get chunks from the label
manager so that they use MPLS_LABEL_BASE_ANY as the base
for the requested chunk

bgpd: honor max prefix timer on inbound sessions
When using the maximum-prefix restart option with a BGP peer,
if the peer exceeds the limit of prefixes, bgpd causes the
connection to be closed and sets a timer. It will not attempt
to connect to that peer until the timer expires. But if the
peer attempts to connect to it before the timer expires, it
accepts the connection and starts exchanging routes again.
When accepting a connection from a peer, reject the connection
if the max prefix restart timer is set.

Both of these hooks are necessary for proper operation of extensions
that need to latch on to a particular instance.
- without the delete hook, it's impossible to get rid of stale

- the config-write hook is necessary because per-instance config needs
to be written inside the "router bgp" block to have the appropriate
context; adding a separate config node can't do that.
