+ + add code to curses.priv.h ifdef'd with NCURSES_CHAR_EQ, which
+ changes the CharEq() macro to an inline function to allow comparing
+ cchar_t struct's without comparing gaps in a possibly unpacked
+ memory layout (report by Miroslav Lichvar).

+ + add new functions to lib_trace.c to setup mutex's for the _tracef()
+ calls within the ncurses library.
+ + for the reentrant model, move _nc_tputs_trace and _nc_outchars into
+ the SCREEN.
+ + start modifying test/worm.c to provide threading demo (incomplete).
+ + separated ifdef's for some BSD-related symbols in tset.c, to make
+ it compile on LynxOS (report by Greg Gemmer).
