Remove all virtual MCE related work into a seperated file.
It also try to do some clean-up on the vMCE, including:
a) renmae some function name like mce_init_msr/mce_rdmsr to be
vmce_init_msr/vmce_rdmsr to make it more straightforward,
b) make the vmca_msrs be a pointer in arch_domain,
to decrease arch_domain's size
c) extract per-bank MCA MSR access to be seperated function
(bank_mce_wrmsr/bank_mce_rdmsr) to make it be a bit cleaner.
d) A new file xen/include/asm-x86/mce.h is added for vmce related
header.

This attempts to address all the concerns raised in
http://lists.xensource.com/archives/html/xen-devel/2009-11/msg01195.html,
but I'm nevertheless still not convinced that all aspects of the
injection handling really work reliably. In particular, while the
patch here on top of the fixes for the problems menioned in the
referenced mail also adds code to keep send_guest_trap() from
injecting multiple events at a time, I don't think the is the right
mechanism - it should be possible to handle NMI/MCE nested within
each other.
Another fix on top of the ones for the earlier described problems is
that the vCPU affinity restore logic didn't account for software
injected NMIs - these never set cpu_affinity_tmp, but due to it most
likely being different from cpu_affinity it would have got restored
(to a potentially random value) nevertheless.

Use a 64bit value instead of extracting/merging two 32bit values.

At least the MSR handling for guests can easily be made shared between
the two vendors; likely a lot of the other code in mce_intel.c could
also be made common. The goal here, however, is to eliminate the
annoying guest-tried-to-modify-msr messages that result from enabling
the MCE code on the Linux side.
Additionally (in order for not having to make the same change twice to
basically identical code) the patch also merges
amd_{fam10,k8}_mcheck_init(), enables the former to also be used for
Fam11 (I'd suppose that Fam12 would also need to go here, but I have
no data to confirm that), and does some minor (mostly coding style for
the code moved around) adjustments.

- fix inverted return value check for intel_mce_{rd,wr}msr()
- fix broken initialization of d->arch.vmca_msrs.mci_ctl
- remove pointless (!d || is_idle_domain(d)) checks
- eliminate hard-coded limit to 9 banks
- avoid redundant gdprintk()s

more robust and designed to make terminal error telemetry available to
the dom0 panic flow for diagnosis on reboot.
Use common code for a lot of the AMD and Intel MCE handling code.
