The save and restore code assumed sizeof(long) == 4, which is not the
case on x64. Reading only 4 bytes from the savefile left the others
uninitialized, which led to problems like billions of experience points
or gold pieces.
state.c now saves the fuse that refills alchemy jugs, using the method
of numbering objects previously applied to Advanced Rogue 5. Alchemy
jugs that are empty when the game is saved will continue to function
after it is restored.
Savefile compatibility should not be affected.
Advanced Rogue 5 and 7, and XRogue, now open the scorefile and logfile
at startup and then drop any set[ug]id privileges if the savedir is not
being used.
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.
