Done with a combination of regex'ing and banging my head against a wall.

YANG model and CLI commands allow user to configure LDP-sync per area.
But the actual implementation is incorrect - all commands are changing
the config for the whole VRF instead of a single area. This commit fixes
this issue by actually implementing per area configuration.
Fixes #8578.

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.

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.

Those constants are also useful in contexts other than LDP-IGP
Synchronization (e.g. the upcoming LFA work will need them). Move
them to a more general header to reflect that.
