* Remove the WCOL family of macros, these were "stealing" the upper bits
of a character attribute to store the column width of a character. No
warning was given about this in curses.h which meant it was easy to
accidentally reuse the bits in use by the WCOL macros (we already did).
Add couple of 16bit ints to the character structure iff HAVE_WCHAR is
true to hold the display width and wide char related flags (just
continuation at the moment)
* Convert all instances of WCOL macros to just reference the column width
in the char structure so it is not obfuscated.
* Fix cursor positioning so placing a cursor in the middle of a wide char
actually does just that.
* Fix plod so it understands that if the cursor is going to be positioned
in the middle of a wide char it cannot just reprint the char to get there.
* Fix plodput so it correctly counts the number of output characters for
wide characters.
* Fix slk routines to properly size the wctomb() buffer.

It is supposed to print a help message without the usage
line. Although it is deprecated and has been removed as of FUSE 3.0,
filesystems in the wild still use it.
* FUSE_MAKE_VERSION(maj, min) now generates a 3-digits number if the
version is higher than 3.9. This is needed to support FUSE 3.10 API.
* FUSE_{MAJOR,MINOR}_VERSION no longer have a fixed value but are
derived from FUSE_USE_VERSION specified by the user code. This is
needed to support more FUSE filesystems in the wild.
puffs_daemon(3) creates a pipe before forking, and the parent process
waits for the child to either complete puffs_mount(3) or fail. If a
user calls puffs_daemon(3) after puffs_mount(3), the function
deadlocks. While this error-reporting functionality is really a nice
thing to have, deadlocking is not great. If the filesystem has already
been mounted, puffs_mount(3) should just daemonize the process and
return.
This became an issue because fuse_daemonize(3) in FUSE API had no such
requirement and some FUSE filesystems in the wild suffered deadlocks.
Remove the DIAGASSERT for str being NULL in the puts/putp functions,
add protection so that the functions just return OK if str is NULL.
This prevents the assert firing when libcurses passes through a NULL
due to an undefined terminfo entry.
