Fix IPL measurement of El Torito CD boot and some eventlog formats.
The TCG BIOS extensions are described here:
https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf
- fix cdrom (El Torito) boot (8.2.5.6 El Torito, p63)
tcpa_ipl() is modified to support various boot devices.
move some measurement code into cdrom_boot() function.
- fix EV_IPL (0Dh) event (10.4.1 Event Types, p76)
eventfield size should be zero
- fix EV_SEPARATOR event (3.2.2 Integrity Collection and Reporting,
p32)
change eventfield to -1 (0xFFFFFFFF) from "---------------"
- add "Returned INT 19h" event (8.2.3 Logging of Boot Events, p59)
actually, tcgbios does not call int19h, but we extend this
tentatively

- portability fix in Makefile: mkhex is not bash specific
- GNU od separates column with one blank, BSD od uses eight blanks.
Change sed to deal with this.
- Add a fourth sed to fix a build error on NetBSD

Once the presence of LPT1 is baked into a Windows guest, it gets upset
if it is subsequently removed. Hence we add the 'LTP1' device object
back into the ACPI DSDT, and remove IRQ 7 from the list of IRQs usable
by the PCI-ISA links.

RHEL4U4 PAE SMP guest currently crashes, and we found changeset 15214
introduced it. This patch fixes it.

It turns out that although PIIX4 hardware defines the S5 type code to
be 000, all OSes will discover the correct code by evlauating an \_Sx
object in the ACPI DSDT. And we set the type code in that object to be
111.
So this patch keeps the other cleanups made to the piix4acpi.c file,
but switches back to checking for code 111. It also makes it clearer
in both the ioemu code and in the dsdt source code where these magic
numbers come from.
Let's hope noone actually has the true PIIX4 type codes hardcoded
(it's highly doubtful that anyone would).

extensions. mdelay() can more easily be implemented by polling the
DRAM refresh bit in port 0x61. And this does not mess with state that
a guest may be relying on.

Was reading argument from wrong stack location with recent versions of
bcc. Doing the access from [bp] rather than [sp] is safer as the
former does not change all the time.

- Add a missing break into the switch statement
- Simplify the code that switches from protected mode into real mode
by letting it spill eax; this also fixes the case where the stack is
above 0xffff.
- reformat the source for 80 columns
- remove some comments that were relevant when the TCG extensions were
direct part of the real-mode Bochs BIOS

FADT only to XSDT. It avoids a buffer overflow in the initialization
of Window 2000 ACPI HAL (pre ACPI 2.0 OS), and thus enables the
installation and boot. This compatibility practice is also used in
hardware, please refer to:

definition from the ACPI DSDT. This avoids conflict with FDC on IRQ6
(it is a bit more likely that someone will want to connect a floppy
image to a guest than it is that anyone will ever care about
parallel-port functionality).
