Ok, I've merged this, although I've tweaked things substantially in
the process.  I did rename "header_tree" to "boot_info", moved some
things around, and changed the syntax.  Reserve ranges can now be
specified either as an address and length:

	/memreserve/	10000000 00002000;

or as an (inclusive) address range:

	/memreserve/	10000000-10001fff;

I am a bit worried that those two forms may be hard to distinguish at
a glance.  Any sugggestions for changes to the syntax soon please, I'd
really like to keep the source syntax as stable as possible.
