[syslinux] SYSLINUX 3.74-pre17: (hopefully final) release candidate

[H. Peter Anvin]

Let's try to get this thing released.  Dag: will you do your RPM
buildathon on this drop?

Changes in 3.74:
        * New UI directive, which allows a more natural way to specify
          a menu system (or not.)  With the UI directive specifying
          the menu system, the DEFAULT directive can be used to select
          the default entry inside the menus.
        * kbdmap.c32: new module to load a new keyboard map
          dynamically.
        * isohybrid: workaround bug in some versions of binutils.
        * Fix issue with the placement of the initrd on some machines.
        * ifcpu64: fix handling of less than three arguments.
        * Fix bug in the shuffle library when dealing with a very
          large number of fragments.
        * Documentation fixes by Vicente Jimenez Aguilar.
        * gPXE updated to version 0.9.7.
        * hdt.c32: Hardware Detection Tool, an interactive hardware
          analyzer module by Erwan Velu.
        * MEMDISK: enable automatic determination of the disk geometry
          for a large floppy disk image if (and only if) it is
          formatted with a FAT filesystem.
        * SYSLINUX: fix the handling of .bss files on FAT12/16.
        * Suppress the Loading ... message if "quiet" is specified on
          the kernel command line.
        * Fix the use of "CONSOLE 0" with menu.c32.
        * Allow COM32 modules to be aware of all memory even in the
          presence of a memory hole.  The "linux.c32" module can be
          used to load a kernel (or memdisk) plus large initrd on
          such a system.
        * MBR: produce alternate MBR variants which force the drive
          number to hd0 (_f variants), or force the drive number to
          hd0 if the Ctrl key is pressed (_c variants.)  Furthermore,
          add an MBR variant (altmbr*.bin) which ignores the active
          flag and instead boots the partition number specified in the
          byte at offset 439 decimal.
