Rewrite of smbcontrol - it was a bit of a mess. It should now be much
nicer to use and more hackable. - converted to popt - text message destinations (except for broadcast smbd) are resolved using files in piddir so the string 'winbindd' is now a destination - added --timeout option to specify timeout value - deleted complicated handling of debug args as separate command line arguments: use shell quoting instead - deleted interactive mode as punishment for using strtok() (-: - much improved command line argument checking Some of this stuff was broken before I started (print notify, profiling) but the basics still work (ping, pool-usage, debug, debuglevel). (This used to be commit 269f838dee257ee9badcae190f2c70b898676bc5)
