* Added code to __restartwin to restore meta and cursor visibility states
* Added code to __stopwin to disable meta.
* Added the *line group of functions for drawing character lines.
* Added Bill's fixes for errors when compiling with WARNS=1
* Incorporated fixes to make usage of unctrl consistent in debug and
made improvements to ctrace - it now timestamps it's output better.
* Reduced the number of mallocs done by __init_getch by allocating key
structs in bunches instead of singly.
* Removed the shadowing of global declarations in newwin and subwin
functions
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
