Fixed in uavsrv_run, writing SOCKREADY to sock member in uavsrv.
Use of sockaddr_storage instead of sockaddr to abstract the use of IPv4 or IPv6.
Moved central station and interface configuration to their own functions config_central and config_interface.
Removed now useless member if_addr in options.
Added flag -Wall for compiler. Fixed warnings and added forward declaration of functions in uav_server.c.
Added use of syslog.
