* For some weird reason appending the base directory to the root syslinux.cfg
we create does not appear to work with Slax. So we now always patch ldlinux.sys
to include the base directory.
* Also add an exception to move the /slax/boot/EFI directory to /EFI.
* It should be noted that, as of slax-64bit-slackware-15.0.3.iso, the Slax UEFI
Syslinux bootloaders appear to be broken (since creating a media without using
Rufus at all per the Slax documentation does *not* produce a USB drive that was
bootable in UEFI mode on 2 of the machines I tried).
* Also clean up some iso.c code and fix some unreachable code in ntfssect.c.
* Closes#2336.
* Closes#2338.
* Could be useful for current tails user (6.03 based, same as ours)
who want to create an UFD without downloading files.
* Also improve the buffer overflow check in syslinux/libinstaller/syslxmod.c
* Some stupid corporate firewalls will return garbage content for ldlinux.bss/ldlinux.sys
instead of a 403 (as they really should), which creates an issue with the code written
by the Syslinux people, as they forgot to check for potential overflows...
