syslinux's KERNEL command tries to autodetect the type of the kernel
by looking at the file's extension. This is unsafe, use the explicit
versions instead:
LINUX - for Linux kernels (memtest is booted like a Linux kernel, too)
COM32 - for COM32 modules
COMBOOT - for comboot modules (only poweroff.com right now)
See http://syslinux.zytor.com/wiki/index.php/SYSLINUX#KERNEL_file
The name of the bootloader is syslinux, while isolinux is just one
of many components. isolinux.bin now also accepts syslinux.cfg
as a configuration file name (as do all other loaders).
Thus, rename the isolinux/ folder to syslinux/, and rename
isolinux.cfg to syslinux.cfg. The only occurrence of 'isolinux'
is now the actual loader file 'isolinux.bin'. This makes
the transition from isolinux to the other syslinux loaders
easier when remastering the ISO onto another medium.
