Automatically reformat com32/lib/syslinux/zonelist.c using Nindent.

Do this for all files except HDT, gPXE and externally maintained
libraries (zlib, tinyjpeg, libpng).

syslinux_add_memmap() would fail miserably and corrupt the list if an
entry was added at address zero.  Quite possibly other addresses would
have similar problems.  Furthermore, we did an extra "optimization
pass" which should never have been necessary if the algorithm had been
correct in the first place.

This should hopefully fix ALL those bugs.

We can't use continue; since we're not using a for loop; we have to
advance to the next list entry...

KVM uses V86 mode to simulate real mode.  This causes problems with
the new shuffler.  This changes the shuffler handover to be in
16-bit protected mode instead, and requires the stub to do the actual
entry to real mode.  For the KVM hack to work, all segments must have:

(seg.base & 0xfff0000f) == 0 && seg.limit == 0xffff

As a result, we have to make sure the real-mode entry stub is
paragraph-aligned, lest we violate the first criterion.

Make the new shuffler actually work.  This includes changing
rllpack.inc to run in 32-bit mode (since simple_pm_call now switches
to 32-bit mode) and changing the new shuffler interface to move the
shuffle list before actually doing any work.

The old code could fail to coalesce backwards in the case where a
range is totally obliterated.  For now, just scan the whole list.
