On advice of hpa: be more patient with the KBC and SCPA methods; retry

in a long loop before giving up on them. Record method which worked
and default to that method on next attempt.

Use fast in-situ test for gate A20 being set, to cut down on the
...
number of (potentially very slow) gateA20_set operations.
Die with a fatal error if we are unable to set gate A20; if this fails
then we are bound to experience memory corruption at a later stage,
and I'd prefer to pick it up early.

Set up %ds *before* testing a value in our data segment (d'oh!).
...
Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.
Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.
