[isf-wifidog] Some even newer features

[Mina Naguib]

Just to let everyone know that I've merged the "wdctlrestart" branch  
(a.k.a. "Look Ma! No Downtime!") into the main trunk.  Here's the  
appropriate ChangeLog entry:

2005-09-24 Mina Naguib <mina at ilesansfil.org>
* New wdctl command "restart" which will get wifidog to restart  
itself while preserving the existing clientlist.  Perfect for 0- 
downtime upgrading!
* safe.c: New safe_fork that croaks if the fork fails, also takes  
care of closing some global file descriptors for the child
* debug.c: Now also logs the PID as part of every entry
* gateway.c: Handler for SIGCHLD now waitpid()s with WNOHANG flag to  
prevent deadlock when the handler is called and another wait() or  
waitpid() is used
* util.c: execute() now uses waitpid() instead of wait() to reap only  
the child it fork/executed
* Extra debugging entries throughout code

As always, bug reports/fixes/suggestions/beatings gladly accepted.
