Games which run setgid from dm, but don't need to, should drop their
privileges at startup.
Games which have a scorefile should open it at startup, then drop all
privileges leaving just the open writable file descriptor. If the
game can invoke subprocesses, this should be made close-on-exec.
Games with scorefiles should make sure they do not get a file
descriptor < 3. (Otherwise, they could get confused and corrupt the
scorefile when using stdin, stdout or stderr.)

BSD version where the SYSV version isn't needed is insignificant.
This patch therefore simplifies the code by making there be just one
version, a more paranoid (about EOF when errno is already EINTR)
version of the SYSV code. Since the BSD/SYSV defines are mainly used
to control whether BSD timers are used, this helps where BSD timers
but SYSV EINTR handling are wanted.

open the score file at the start and then drop all setgid privileges
while keeping a (close-on-exec) file descriptor open to it. In order
to allow this the static data files have to be made world readable.
In addition a potential buffer overrun with corrupted score files is
avoided by more careful use of scanf (note that SCORE_SCANF_FMT is
defined alongside the definition of the relevant structure).

adventure(6). The handling of this variable is somewhat confusing,
since it is used for two different purposes (controlling the time
required before a saved game can be restored, and controlling various
aspects of dwarf behaviour); in fact, it is also declared twice in
hdr.h. Except possibly when saving a game fails, these uses can never
interfere; when used for controlling dwarf behaviour, we always have
saved == -1. This can be better understood with reference to the
original PDP-10 FORTRAN source (URL in patch, since hdr.h references
the comments of the FORTRAN as still relevant to this version) of
which the C version is a direct translation: the wrong value for
`saved' meant that someone was cheating and had bypassed normal
initialisation. Saving was done by halting and telling the user to
save their core image, so the question of carrying on after saving
failed to open the output file did not arise.
This patch separates the uses of `saved' into uses of two separate
variables.

for an unused function that was removed earlier; and removes a control

that effect in any of the BSD source trees I have handy) but no longer
