Removing the obsolete ldp-sync periodic 'hello' message.
When ldp-sync is configured, IGPs take action if the LDP process goes down.
The IGPs have been updated to use the zapi client close callback to detect
the LDP process going down.

In some extraordinary circumstances an LSP might not have any
TLV. Add a null check to prevent a crash when that happens.

In ldpd, the child processes send IPC messages to the main process to
perform logging in their behalf (access to the file descriptor used
for logging needs to be serialized). This commit fixes a problem
that was preventing the printfrr format specifiers from working in
the child processes, since vsnprintf() was being used instead of
vsnprintfrr() before sending the log messages to the parent process.

When ldp-sync is configured, IGPs take action if the LDP process goes down.
Currently, IGPs detect the LDP process is down if they do not receive a
periodic 'hello' message from LDP within 1 second.
Intermittently, this heartbeat mechanism causes false topotest failures.
When the failure occurs, LDP is busy receiving messages from zebra for a
few seconds. During this time, LDP does not send the expected periodic
message.
With this change, IGPs detect LDP down via zapi client close message.

Following functions is using writen to dispatch message
into socket, but another function uses zserv_send_message.
This commit does tiny unification for zapi's socket messaging.
Funcs:
- zsend_assign_label_chunk_response()
- zsend_label_manager_connect_response()

The `show ip nht` and `show ipv6 nht` commands were broken.
This is because recent code commit: 0154d8ce45
assumed that p must not be NULL and this is not the case.

In bgp_zebra_announce when iterating over multipath
we were checking to ensure that the nexthop was updated
but never initially clearing the nh_updated variable.
Thus leading to a situation where we could crash.

Currently, IGPs are coded to receive a 'hello' message from LDP every second.
Intermittently, LDP Sync topotests are failing because the IGPs fail to
receive this 'hello' message every second.
When the LDP Sync topotests fail, LDP logs show that LDP is processing
zapi messages for 1-2 seconds.
This is a shortterm fix, in order to prevent CI pipeline failures.
The longterm fix is in progress.
