Move x86 specific PC declarations to a separate file

x86 definitions (especially CPUState uses) prevent many files from
being compiled within libhw.

Move x86 specific declarations (APIC stuff) to a separate file.

New qdev_init_nofail()

Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because...

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something

RTC polling mode broken

The RTC emulation does not set the IRQ flags independent of the IRQ enable bits.

The original MC146818A datasheet from 1984 notes:
"flag bits in Register C [...] are set independent of the
state of the corresponding enable bits in Register B"...

Revert "Introduce reset notifier order"

This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and
updates later added users of qemu_register_reset), we solved the
problem it originally addressed less invasively.

Change RTC time drift IRQ re-injection (Gleb Natapov)

Currently IRQ are reinjected as soon as they are acknowledged to
the RTC, but Windows sometimes do acknowledgement in a loop with
global interrupt disabled waiting for interrupt to be cleared and
it does not mask RTC vector in PIC/APIC while doing this. In such...

Support epoch of 1980 in RTC emulation for MIPS Magnum

On the MIPS Magnum, the time that is held in the RTC's NVRAM should be
relative to midnight on 1980-01-01. This patch adds an extra parameter
to rtc_init(), allowing different epochs to be used. For the Magnum,...
