Some games' implementation of md_hasclreol() poked around in ncurses
internals, which does not work for some ncurses build configuration.
Most games did not actually call md_hasclreol(), so it was removed.
There is a standard terminfo function which can retrieve the value of
the clr_eol capability, so this was used for rogue5.
The new function md_random_seed() has replaced time() + getpid() and
similar methods. Putting everything in mdport.c slightly reduces the
warnings and workarounds.
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.
curses.h is already included in rogue.h and doesn't need to be included
twice more in mdport.c.
Also set flags for some features when they are present.
The implementation was copied from rogue4. Using fdopen() is necessary
because the scorefile needs both encread() and encwrite(). For some
reason I have failed to discover, one of them uses FILE *'s and the
other uses file descriptors.
