Gw.h contained a fair amount of obsolete function declarations, duplicate declarations of functions declared in utils.h and declarations of functions that conceptually are similar to those in utils.h. The obsolete and duplicate ones were removed and all but one of the remaining moved to utils.h. Correspondingly the implementation was moved from gw_utils.c to utils.c. The one remaining function - gw_daemonize() - is not really worthy of a file of its own, so that is to be moved to gateway.c after which gw_utils.c can be removed. Gw.h still contains defines that are duplicated in maxscale/protocol/mysql.h. The ones in gw.h are to be removed. It appears that the entire gw.h will disappear.
