pimd: fix ip pim hello option does not take in effect
If frr.conf file has pim hello option setup prior to pim sm under an interface, upon frr start/restart hello option cli replayed prior to sm command

Fix the error message when execute ldpd with --enable-tcp-zebra
- If we use the option "--enable-tcp-zebra " to configure, the zclient will use the tcp socket instead of unix domain socket.
- The ldpd will pass the "-z path" options to `frr_opt` and that will execute zclient_serv_path_set to check the domain socket.
- Add the define to ldpd, if the "HAVE_TCP_ZEBRA" has been define, don't pass the "-z path" to `frr_opt`.
Fix: reverse logic of when to pass the supplied group address
This was causing a crash when no group address was passed
because a garbage pointer valuse was used. It also was ignoring
the group address when passing one.
We shouldn't check the operational status of an interface in ldpd if
it's configured with "no link-detect" in zebra. That's what all the
other routing daemons do.
Restore the original logic in netlink_link_change() which works like this:
* once an interface event is detected, lookup the associated interface
by its name;
* call the set_ifindex() function;
* set_ifindex() will lookup the interface again but now by its ifindex. If
the lookups by name and ifindex yield to different results, then the
interface was renamed and set_ifindex() will take care of that.
In the future, zns->if_table will be split into two different data
structures to allow faster lookups by both name and ifindex.

The use of VTY_DECLVAR_CONTEXT(bgp, bgp) here is wrong as we are not
inside the "router bgp" configuration node. This was making the clear
commands always fail with a "Current configuration object was deleted
by another process" error, which doesn't make any sense.
Also, the bgp_clear() function will already check for us if the given
peer-group or neighbor exists or not, there's no need to duplicate this
logic here.
