Use more portable random seed generation. The new function md_random_seed() has replaced time() + getpid() and similar methods. Putting everything in mdport.c slightly reduces the warnings and workarounds.

    Cursor/Keypad Support

    Sadly Cursor/Keypad support is less straightforward than it should be.

    The various terminal emulators/consoles choose to differentiate the
    cursor and keypad keys (with modifiers) in different ways (if at all!).
    Furthermore they use different code set sequences for each key only
    a subset of which the various curses libraries recognize. Partly due
    to incomplete termcap/terminfo entries and partly due to inherent
    limitations of those terminal capability databases.

    I give curses first crack at decoding the sequences. If it fails to decode
    it we check for common ESC-prefixed sequences.

    All cursor/keypad results are translated into standard rogue movement
    commands.

    Unmodified keys are translated to walk commands: hjklyubn
    Modified (shift,control,alt) are translated to run commands: HJKLYUBN

    Console and supported (differentiated) keys
    Interix:  Cursor Keys, Keypad, Ctl-Keypad
    Cygwin:   Cursor Keys, Keypad, Alt-Cursor Keys
    MSYS:     Cursor Keys, Keypad, Ctl-Cursor Keys, Ctl-Keypad
    Win32:    Cursor Keys, Keypad, Ctl/Shift/Alt-Cursor Keys, Ctl/Alt-Keypad
    DJGPP:    Cursor Keys, Keypad, Ctl/Shift/Alt-Cursor Keys, Ctl/Alt-Keypad
