[syslinux] SYSLINUX 3.10-pre11

pre12 does not fix the problem. booting password protected entries after 
pressing ctrl-c is still possible.
It even got worse: holding down the shift key on boot results in a boot 
prompt in spite of NOESCAPE 1.

> Also, in 3.10-pre12, chainloading secondary menus should now work better.

What did you change?
