Every time a nodemap is contructed the node IP addresses all need to
be parsed. This isn't very productive use of CPU.
Instead, parse each string once when the nodes file is loaded. This
results in much simpler code.
This code also removes the use of ctdb_address. Duplicating the port
is pointless without an abstraction layer around ctdb_address. If
CTDB gets an incompatible transport in the future then add an
abstraction layer.

When sending messages to clients, ctdb checks for EAGAIN error code and
schedules next write in the subsequent event loop. Using sys_write in
these places causes ctdb to loop hard till a client is able to read from
the socket. With real time scheduling, ctdb daemon spins consuming 100%
of CPU trying to write to the client sockets. This can be quite harmful
when running under VMs or machines with single CPU.
This regression was introduced when all read/write calls were replaced to
use sys_read/sys_write wrappers (c1558adeaa).
The existing code backs off in case of EAGAIN failures and waits for an
event loop to process the write again. This should give ctdb clients
a chance to get scheduled and to process the ctdb socket.

If something unexpectedly uses fork() then an exiting child will
remove the PID file while the main daemon is still running. The real
test is whether the current process has the PID of the main CTDB
daemon, which is the process that calls setsid().
This could be done using getpgrp() instead. At the moment the
eventscript handler harmlessly calls setpgid() - harmless because the
atexit() handlers are cleared upon exec(). However, it is possible
that process groups will be used more in future so it is probably
better to rely on the session ID.
