16b29ae180 Add HPET emulation to qemu (Beth Kon) 
This patch adds HPET emulation.  It can be disabled with -disable-hpet.  An hpet
provides a more finely granular clocksource than otherwise available on PC.
This means that latency-dependent applications (e.g. multimedia) will generally
be smoother when using the HPET.

1a7de94aa4 De-assert PIC IRQs properly at APIC level 
[ Taking latest isapc changes into account. ]

Ensure that PIC-delivered IRQs are properly de-asserted in case the APIC
is in EXTINT or FIXED mode (with level-triggering selected) on LINT0.
Fixes EFI-BIOS boot issues.

This patch also cleans up a bit the interface between PIC and APIC,
making apic_local_deliver private again.
