[syslinux] Advanced Menu features

[Murali Ganapathy]

Hi All,

I hope to find some time to work on the Advanced menu system. I
personally no longer have a need for it (changed jobs). Since I dont
want to spend time doing stuff which will not be useful, I would to
know what features you would like.

What I have in my list are

* Eliminate the need to compile each menu into its own .c32 file
* Eliminate #define constants in menu.h which impose various restrictions
  (Max # menus, Max # items in a menu, ...)
* Add VESA Graphics support (hopefully it is easy)
