Determine src based on nexthop data even when we are using
kernel nexthop objects.
Before, we were entirely skipping this step and just sending the
nexthop ID, ignoring src determination.

Having a full feed this leads to unknown. You can't point which prefix or
aspath has this malforming behavior.
Printing just `[EC 33554434] AGGREGATOR attribute is BGP_AS_ZERO(0)` isn't
enough, you can't directly pin-point where is the problem.
Additionally print at least aspath here:
```
[EC 33554434] AGGREGATOR AS number is 0 for aspath: 65000 65031
```
Overall the full table has only 6 such malformed prefixes:
```
aspath: 64539 15096 6939 45430 45458
aspath: 64539 15096 6939 1299 3257 34984 34984 34984 34984 34984 51174

Line break at the end of the message is implicit for zlog_* and flog_*,
don't put it in the string. Mid-message line breaks are currently
unsupported. (LF is "end of message" in syslog.)

This just generates log messages in bulk for testing logging backend
performance. It's in sharpd so the full "context" of being in a daemon
is available (e.g. different logging configs, parallel load in the main

Adapt the zebra route map code to use the transaction CLI output (e.g.
the CLI show callbacks) instead of the fallback compatibility.

Problem seen that if "import vrf route-map RMAP" was entered
without any vrfs being imported, the configuration was displayed
as "route-map vpn import RMAP". Additionally, if "import vrf
route-map" was entered without specifying a route-map name,
the command was accepted and the word "route-map" would be
treated as a vrf name. This fix resolves both of those issues
and also allows deleting the "import vrf route-map" line without
providing the route-map name.

Modify code to use lookup function agg_node_get_prefix()

Problem: This happened in once in a while during testing the scenario multiple
times. When regstop timer expire and at that point if rpf interface doesn't
exist, the register state for the upstream gets struck in reg-prune state indefinitely.
This will not recover even when rpf comes back and traffic resumed because
register state is struck on prune.
RCA: Reg suppression expiry is keeping reg state unchanged when iif is absent.
Fix: When iif is absent during reg suppression expiry, treat it as couldreg
becoming false and move it NO_INFO state.

Zebra is currently sending messages on interface add/delete/update,
VRF add/delete, and interface address change - regardless of whether
its clients had requested them. This is problematic for lde and isis,
which only listens to label chunk messages, and only when it is
waiting for one (synchronous client). The effect is the that messages
accumulate on the lde synchronous message queue.
With this change:
- Zebra does not send unsolicited messages to synchronous clients.
- Synchronous clients send a ZEBRA_HELLO to zebra.
The ZEBRA_HELLO contains a new boolean field: sychronous.
- LDP and PIM have been updated to send a ZEBRA_HELLO for their
synchronous clients.
