Automatically reformat com32/lib/syslinux/memmap.c using Nindent.
Do this for all files except HDT, gPXE and externally maintained
libraries (zlib, tinyjpeg, libpng).

Merge the memory map discovery for malloc and the memory map discovery
for memmap into one file that scans memory and invokes a callback.

Impact: should deal with memory holes more gracefully
Right now, if we find a memory hole, we simply don't use the memory
beyond that point. This makes it possible for com32 modules to
use that memory. After this, we should be able to add relocation
support to allow loading when the memory at 1 MB is unavailable.

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.

Pre-initialize the e820 buffer to all zero, except for the active bit;
we have found that BIOSes will make assumptions about the pre-existing
value of the buffer and this seems the most conservative value.

Fix reversed test when looking for extattr in e820: force the extattr
values only when they are *not* present...

Some blithering idiot thought it was a good idea to introduce
"extended attributes" for INT 15h, AX=E820h, and in doing so, breaking
compatibility with ALL E820 users out there. F*cking morons.
Implement handling of extended attributes in:
- e820 parsing in the core
- e820 parsing in libcom32
- e820 parsing *and proxying* in memdisk
The latter is the really painful one.

The shuffle and boot interface, including the library support, should now
work as advertised. Add an ELF-loading module as a demo, and it's probably
useful for someone, too.

Initial checkin of a wrapper infrastructure for the "shuffle and boot"
interface, both real and protected mode. This code automatically will
figure out the necessary sequence of moves, taking into account swaps
and overlaps as necessary.
