i386/xen: implement HVMOP_set_evtchn_upcall_vector
The HVMOP_set_evtchn_upcall_vector hypercall sets the per-vCPU upcall
vector, to be delivered to the local APIC just like an MSI (with an EOI).
This takes precedence over the system-wide delivery method set by the
HVMOP_set_param hypercall with HVM_PARAM_CALLBACK_IRQ. It's used by
Windows and Xen (PV shim) guests but normally not by Linux.

hw/xen: Add xen_overlay device for emulating shared xenheap pages
For the shared info page and for grant tables, Xen shares its own pages
from the "Xen heap" to the guest. The guest requests that a given page
from a certain address space (XENMAPSPACE_shared_info, etc.) be mapped
to a given GPA using the XENMEM_add_to_physmap hypercall.
To support that in qemu when *emulating* Xen, create a memory region
(migratable) and allow it to be mapped as an overlay when requested.
Xen theoretically allows the same page to be mapped multiple times
into the guest, but that's hard to track and reinstate over migration,
so we automatically *unmap* any previous mapping when creating a new
one. This approach has been used in production with.... a non-trivial
number of guests expecting true Xen, without any problems yet being
noticed.
This adds just the shared info page for now. The grant tables will be
a larger region, and will need to be overlaid one page at a time. I
think that means I need to create separate aliases for each page of
the overall grant_frames region, so that they can be mapped individually.

i386/kvm: Set Xen vCPU ID in KVM
There are (at least) three different vCPU ID number spaces. One is the
internal KVM vCPU index, based purely on which vCPU was chronologically
created in the kernel first. If userspace threads are all spawned and
create their KVM vCPUs in essentially random order, then the KVM indices
are basically random too.
The second number space is the APIC ID space, which is consistent and
useful for referencing vCPUs. MSIs will specify the target vCPU using
the APIC ID, for example, and the KVM Xen APIs also take an APIC ID
from userspace whenever a vCPU needs to be specified (as opposed to
just using the appropriate vCPU fd).
The third number space is not normally relevant to the kernel, and is
the ACPI/MADT/Xen CPU number which corresponds to cs->cpu_index. But
Xen timer hypercalls use it, and Xen timer hypercalls *really* want
to be accelerated in the kernel rather than handled in userspace, so
the kernel needs to be told.

It will also cover the support for architecture-independent grant table

The XEN_BUS option is for the xenfv platform support, which will now be

The XEN option remains dependent on the Xen runtime libraries, and covers
support for real Xen. Some code which currently resides under CONFIG_XEN

Xen runtime libraries are eliminated. The Xen PCI platform device will

scripts/checkpatch.pl: Do not allow assert(0)
Since commit
262a69f428 ("osdep.h: Prohibit disabling assert()
in supported builds") we can not build QEMU with NDEBUG (or
G_DISABLE_ASSERT) defined, thus 'assert(0)' always aborts QEMU.
However some static analyzers / compilers doesn't notice NDEBUG
can't be defined and emit warnings if code is used after an
'assert(0)' call.
Apparently such compiler isn't as clever with G_DISABLE_ASSERT,
so we can silent these warnings by using g_assert_not_reached()
which is easier to read anyway.
In order to avoid these annoying warnings, add a checkpatch rule
to prohibit 'assert(0)'. Suggest using g_assert_not_reached()
instead. For example when reverting the previous patch we get:
ERROR: use g_assert_not_reached() instead of assert(0)
#21: FILE: target/ppc/dfp_helper.c:124:
