Functions for starting and stopping daemons and fuses now expect the
type 'void (*func)()'. Only a few functions in XRogue needed to be
modified to fit. Determining the type of the argument is left for a
later date.
Building with GCC5 should now produce less than 200 lines of warnings
per game.
Arrays of struct delayed_action were declared before the definition.
Also, daemon.c and state.c defined it differently. The state.c
definition, in which d_arg is a union, is now used everywhere.
This is the least bad option, but fuses and daemons are still a
disheartening morass that undoubtedly shelters more bugs.
