* Major code base changes; all filesystem rewritten in C.
This work was done primarily by Liu Aleaxander (Yuanhan Liu).
* Better support for booting from MBRs which don't pass
handover information.
* EXTLINUX: Try to be smarter about finding the partition
offset.
* chain.c32: support chainloading Dell Real Mode Kernel (Gene
Cumm).
* chain.c32: fix booting in CHS mode.
* Fix the -s option to the syslinux/extlinux installer (Arwin
Vosselman).
* isohybrid: fix padding of large images (PJ Pandit).
* SYSLINUX: correctly handle the case where the -d option is
specified with a non-absolute path, i.e. "syslinux -d
syslinux" instead of "syslinux -d /syslinux".
* ISOLINUX: recognize the directory names /boot/syslinux and
/syslinux, and the filename syslinux.cfg in addition to the
isolinux-specific names. Thus, "syslinux.cfg" is now a
generic name, whereas "isolinux.cfg" or "extlinux.conf" is
specific to different derivative.
* chain.c32: support setting alternate config filename for
stage2 of GRUB Legacy (Gert Hulselmans).
* whichsys.c32: execute specific command, based on Syslinux
bootloader variant (Gert Hulselmans).
* lua.c32: a lot of new bindings added to the "syslinux"
namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter).
* btrfs: print a comprehensive error message if compressed or
encrypted files are encountered (neither is currently
