[syslinux] SYSLINUX 3.62-pre7: no more 64K limit on CLI labels

[H. Peter Anvin]

3.62 is shaping up to be the "let's get rid of hardcoded limits" 
release.  I got inspired by Bryan Perry's post about people still 
wanting to be able to use the CLI, so I have implemented putting labels 
in high memory, therefore avoiding the 64K total limit.

This is now released as 3.62-pre7.  If you happen to have a use case for 
this, I would be interested in finding out how well it works.

Next, I'll probably try to get rid of the hardcoded limits in the menu 
system (currently limited to 4096 labels per menu), and if I get really 
ambitious, implement a better submenu system.
