[syslinux] menu.c32 - Return from sub-menu

[Murali Krishnan Ganapathy]

The python script is complete and should be available with the next 
pre-release of SYSLINUX. Also added things to the menu API which should 
make write a parser in C a lot easier.
As usual, there might be minor bugs in the code, but for the most part 
it should work.

Regarding using yacc or lex: Potential problem is that, the generated C 
code needs to be linked in with "libfl". I don't know if that library 
contain non-rommable code, i.e. code which cannot be run under SYSLINUX 
and does not use libc for instance.
