These were unused apart from some stray forward declarations in
tools/ctdb.c and a single call in ctdb_set_runstate(), where
ctdb_runstate_to_string() can be used instead.

"addip"/"delip" are different from "moveip" so they don't need to
call ipreallocate() nor send_ipreallocated_control_to_nodes().

This matches the behavior of takeover_send/recv() from
ctdb_takeover_helper.c.
It means we consistently call the ipreallocated event scripts
and also send CTDB_SRVID_IPREALLOCATED after moving ips.

That makes the behavior more consistent compared to a takeover run
started from the within ctdbd.
The behavior is the same but ctdb_message_disable_ip_check() used
a legacy code path and the next commits will also touch some
of the moveip logic...
The logic and comments are copied from control_reloadips().

DEBUG level logging in ctdb_killtcp is very noisy. The most important
messages when debugging are those for tickle ACKs and TCP RSTs. TCP
RSTs are already logged at INFO level, so promote tickle ACKs to INFO
level too.

When a node is starting, CTDB reports remote nodes as unhealthy by
default. This can be misleading.
To hide this, report an "UNKNOWN" pseudo state when a remote node is
not disconnected and the runstate is less than or equal to
"FIRST_RECOVERY".

This has been broken for 10 years since commit
9616959bd6, which introduced the
separate filtering. This commit was missing a redirect of the output
of stderr_filter() to stderr.
Since nobody depends on the separate filtering (i.e. nobody reported a
bug), just return to combining stdout and stderr, and filtering them
together.

This filter no longer does anything useful in this context. By
default it adds a pipeline with trailing cat process. In many
contexts, stdout of the process being run is still open so the cat
process will stay around and will stop onnode from exiting.
The filters should all go away because they are simply an example of
code that is trying to be too clever while causing unfortunate corner
cases.
