[PATCH 1/4] Use NCURSES_CONST in func_key declaration

[Pavel Roskin]

This fixes a warning

wkeys.c: In function '_initkeys':
wkeys.c:128: warning: passing argument 1 of 'tgetstr' discards qualifiers
from pointer target type
/usr/include/termcap.h:63: note: expected 'char *' but argument is of type
'const char *'

NCURSES_CONST is normally empty for compatibility with other curses
implementations, but ncurses can be compiled with NCURSES_CONST set to
"const" for extra strictness.  By using NCURSES_CONST, the code would
cause no warnings either way.
