984c3f4f66 ctdb-common: Start listening to sockets only on successful startup
Fix tests to use wait_send() instead of startup() as a synchronization
point to ensure that the socket is listening.

ad8d72091e ctdb-common: Fix stale socket removal
Sockets need to be created from sock_daemon_run_send().  This means
that stale socket removal can depend on the PID file context being
initialised.

Also fix associated test.

b67cc00c93 ctdb-common: Move PID file creation to sock_daemon_run_send()
Only create PID file when actually starting the daemon, rather than
when setting up the context.  This will facilitate future changes.

Tweak test to confirm that PID file is no longer created during setup.

ed722c3aa9 ctdb-common: Add wait_send/wait_recv to sock_daemon_funcs
BUG: https://bugzilla.samba.org/show_bug.cgi?id=12510

To be able to terminate the daemon from within the implementation,
create a subreq using wait_send() provided by the implementation.
When the subreq is finished, it signals the sock_daemon code to terminate
the daemon.

This avoids the need to keep track of the top level tevent_req causing
layer violation and keeps the code flow straighforward.
