Clean up warnings: popt sure does some strange things
popt generates 4 compiler warnings with GCC 4.6. There are 2
different types:
* 3 instances of:
warning: cast discards ‘__attribute__((const))’ qualifier from pointer target type [-Wcast-qual]
One occurs in the _free() hack that is used to try and avoid a
compiler warning. I guess GCC got smarter? ;-)
The other is where an array of constant strings is passed to
execvp(2), which arguably has the wrong type, since it has no need
to modify the strings.
Both of these can be worked around by casting to intptr_t before
casting to the desired argument type.
In poptReadConfigFile() the variable file is declared to be a
constant string. However, it is then passed to read(2) straight
away and an attempt is made to cast away the "const". However, to
protect the value the of file is assigned to (const char *) chptr
before it is passed to any other functions, so this protects the
value anyway. I'm not sure exactly what the thinking was
here... but there seems to be no use having file be constant.
* 1 instance of:
warning: variable ‘rc’ set but not used [-Wunused-but-set-variable]
for the result of an execvp(2) call. Recast the return type to
void. However, due to some #if-fu in the function, that can make rc
unused in this function. So we also need to wrap the declaration of
rc in some corresponding #if-fu to make it disappear if not used.

Interface monitoring: add a event to trigger every 30 seconds to check that all interfaces referenced by the public address list actually exists.
This will make it much easier to root-cause problems such as
S1029023
when an external application deleted the interface while it is still is in use by ctdbd.

check that the actual interface exist, print error and fail startup if the interface does not exist.

Add a tunable "AllowClientDBAttach" with default value 1.
When set to 0, clients will not be able to attach to databases
via the db_attach control. This might can be useful for maintenance
where ctdb should be kept running but clients should not be able
to modify databases.

Eventscripts - enhance ctdb_replay_monitor_status()
Print useful output and return a suitable exit code.
The DISABLED and TIMEDOUT statuses use fake negative return codes, and
these can't be faked from the shell. So we map DISABLED to OK and
TIMEDOUT to ERROR - this should avoid nearly all surprises. When we
do this we add a note to the beginning of the output. The alternative
is to "fix" ctdbd to use only codes that can actually be returned by
shell scripts. However, the reason for using negative codes is
probably to distinguish them from real ones...
