Terminate emulation on memory allocation failure (Avi Kivity)

Memory allocation failures are a very rare condition on virtual-memory
hosts.  They are also very difficult to handle correctly (especially in a
hardware emulation context).  Because of this, it is better to gracefully
terminate emulation rather than executing untested or even unwritten recovery
code paths.

This patch changes the qemu memory allocation routines to terminate emulation
if an allocation failure is encountered.

MTRR support on x86 (Carl-Daniel Hailfinger)

The current codebase ignores MTRR (Memory Type Range Register)
configuration writes and reads because Qemu does not implement caching.
All BIOS/firmware in know of for x86 do implement a mode called
Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU
cache like RAM before RAM is enabled. Qemu assumes RAM is accessible
from the start, but it would be nice to be able to run real
BIOS/firmware in Qemu. For that, we need CAR support and for CAR support
we have to support MTRRs.

This patch is a first step in that direction. MTRRs are MSRs supported
by all recent x86 CPUs, even old i586. Besides influencing cache, the
MTRRs can be written and read back, so discarding MTRR writes violates
the expectations of existing code out there.

An added benefit of this patch is that it fixes the following Linux
kernel error message present in recent kernels (provided the BIOS has
the recent MTRR patches applied):

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,
1980 is specified, and for all other machines, 2000 is specified.

I've not modified the handling of the century byte, as with an epoch of
1980 and a year of 2009, one could argue that it should hold either
0, 1, 19 or 20.  NT 3.50 on MIPS does not read the century byte.
