Fix a portability issue with md_hasclreol().
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.

| 789 Cursor/Keypad Support | |
| 790 | |
| 791 Sadly Cursor/Keypad support is less straightforward than it should be. | |
| 792 | |
| 793 The various terminal emulators/consoles choose to differentiate the | |
| 794 cursor and keypad keys (with modifiers) in different ways (if at all!). | |
| 795 Furthermore they use different code set sequences for each key only | |
| 796 a subset of which the various curses libraries recognize. Partly due | |
| 797 to incomplete termcap/terminfo entries and partly due to inherent | |
| 798 limitations of those terminal capability databases. | |
| 799 | |
| 800 I give curses first crack at decoding the sequences. If it fails to decode | |
| 801 it we check for common ESC-prefixed sequences. | |
| 802 | |
| 803 All cursor/keypad results are translated into standard rogue movement | |
| 804 commands. | |
| 805 | |
| 806 Unmodified keys are translated to walk commands: hjklyubn | |
| 807 Modified (shift,control,alt) are translated to run commands: HJKLYUBN | |
