Windows Server 2003 sulks if we feed it an empty region in base memory
...
as a result of our memory map editing, so strip out any empty regions.

Set carry flag before calling INT 15,e801 and INT 15,e820.

Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says
that CF is unreliable for this call.

Cope with regions bigger than 4GB.
...
We now split e820 regions around ourselves, rather than just
truncating the e820 region. This avoids the worst-case scenario of
losing all memory over 4GB.
It's more important to get the memory map right now that we're
expecting to still be loaded when the OS starts in several situations
(e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).
