Sync with HEAD

Add an option to supress the vertical space between menu title and
menu items.

Sync with HEAD, resolve a couple of conflicts

Add (optional) support for expanded static menu texts - that is: whatever
the application programmer defines as expansion, e.g. to implement
parameter substitution.
While here add rudimentary documentation of the dynamic messages
feature (so at least the parser and the syntax documented here
are in sync).
The man page could use some typesetting help...

sync with head

Remove the advertising clause and appease the eye a bit (still not good, but
better).  Almost no functional change.

Pull up revision 1.13 (requested by riz in ticket #5515):
Make '0' be a valid number

Pull up revision 1.14 (requested by riz in ticket #5515):
Support menu windows that preserve the underlying screen contents.
   (Needs a libcurses fix as well).
No need to ponce about with __m_endwin (to remember we've done endwin()),
   the old recovery was wrong in any case - but I've left something that
   will do an explicit redraw.
Allow the 'help' text to be from a variable (and hence translated).
Fix the display of help so that the screen underneath is actually cleared.
Preserve the screen contents while displaying help - redraw is too hard.
Use endwin(); doupdate(); to do the full refresh when ^L is typed.
Move menus up the screen if they would hit the bottom with too few lines
   to show an item and the scroll text (happens with big titles).
Make 'y=0' center the window vertically - use of 0 means you can't have
   a menu starting on the topline, but this is unlikely to be a problem.
Make all the menu options settable from the control file, not just from
   dynamic menus.
Redo menu option list part of man page.

Make '0' be a valid number

Add '[no] clear' to lex/yacc spec.
Fix some menu sizing bugs for menus where the user code changes the size.
Don't reduce the size of a menu with 'scroll' every timeit is displayed.

Allow -ve integer constants in menu file.
Make y == -1 => after current messages (if msg_defs.h included).
Defer menu initialisation until after post_act() called (so function can
fiddle with more things.)

Add extra command 'allow dynamic messages' which will push all texts through
the msgc translation service.
Allow for texts being NULL as well as "", don't use strlen() to test for "".

Tweek the "no shortcut" code.
   MC_NOSHORTKEY to NOSHORTCUT
   added option "shortcut" to menuc input language.
   added example of this kind of menu in testm.

pull up rev(s) 1.8 from trunk. (cgd)

provide a way to set the string used for the 'Exit' menu item.

Small tweeks, redoing language for dynamic menus.

Bug fixes, tweeks to scrolling, beginnings of dynamic menus.

Add scrollable menus. Tweek testm's Makefile to remake if menu_sys.def
is modified.

Add a online help facility.  Each menu can specify a help screen associated
with that menu.  The help screen is scrollable for long help screens.
The char '?' accesses the help screen as a menu command.  Help screen text
is specified in the menu definition file with the menu.

.y.c <sys.mk> rule fixes.  Don't create a y.tab.h file unless asked for,
and use smarter creation of the header file.

Pull rev 1.2 up from trunk (phil)

Add code for handling NULL return from initscr().  Added "ERROR ACTION"
for user code for above error.

Add a curses based menu compiler system.  (Used by the new system install
program sysinst.)
