kvm: x86: Swallow KVM_EXIT_SET_TPR

This exit only triggers activity in the common exit path, but we should
accept it in order to be able to detect unknown exit types.

kvm: Stop on all fatal exit reasons

Ensure that we stop the guest whenever we face a fatal or unknown exit
reason. If we stop, we also have to enforce a cpu loop exit.

kvm: Improve reporting of fatal errors

Report KVM_EXIT_UNKNOWN, KVM_EXIT_FAIL_ENTRY, and KVM_EXIT_EXCEPTION
with more details to stderr. The latter two are so far x86-only, so move
them into the arch-specific handler. Integrate the Intel real mode
warning on KVM_EXIT_FAIL_ENTRY that qemu-kvm carries, but actually...

x86: Optionally dump code bytes on cpu_dump_state

Introduce the cpu_dump_state flag CPU_DUMP_CODE and implement it for
x86. This writes out the code bytes around the current instruction
pointer. Make use of this feature in KVM to help debugging fatal vm
exits....

kvm: introduce kvm_inject_x86_mce_on

Pass a table instead of multiple args.

Note:

kvm_inject_x86_mce(env, bank, status, mcg_status, addr, misc,
                       abort_on_error);

is equal to:

struct kvm_x86_mce mce = {
        .bank = bank,...

kvm: x86: Fix DPL write back of segment registers

The DPL is stored in the flags and not in the selector. In fact, the RPL
may differ from the DPL at some point in time, and so we were corrupting
the guest state so far.

kvm: x86: Remove obsolete SS.RPL/DPL aligment

This seems to date back to the days KVM didn't support real mode. The
check is no longer needed and, even worse, is corrupting the guest state
in case SS.RPL != DPL.

kvm: x86: Prevent sign extension of DR7 in guest debugging mode

This unbreaks guest debugging when the 4th hardware breakpoint used for
guest debugging is a watchpoint of 4 or 8 byte lenght. The 31st bit of
DR7 is set in that case and used to cause a sign extension to the high...
