Bifurcate the interrupt establish functions between XEN and non-XEN

Thus intr_establish_xname() becomes xen_intr_establish_xname() etc.

One consequence of this is that dom0 devices expect the native
function calls to be available and we thus provide weak aliasing for
dom0 builds to succeed. XEN and non-XEN devices are distinguished by
the PIC they are established on. XEN interrupts are exclusively
established on xen_pic, while dom0 interrupts are established on
natively available PICs.

This allows us an orthogonal path to xen device management (eg:
xenstore events) in XENPVHVM, without having to worry about unifying
the vector entry paths, etc., which is quite challenging.

add support for kern.intr.list aka intrctl(8) 'list' for xen

event_set_handler() and pirq_establish() now have extra intrname
parameter; shared intr_create_intrid() is used to provide the value

xen drivers were changed to pass the specific driver instance
name as the xname, e.g.  'vcpu0 clock' instead just 'clock', or
'xencons0' instead of 'xencons'

associated evcnt is now changed to use intrname - this matches native x86

KNF. Remove extra spaces. No functional change.

Merge jym-xensuspend branch in -current. ok bouyer@.

Goal: save/restore support in NetBSD domUs, for i386, i386 PAE and amd64.

Executive summary:
- split all Xen drivers (xenbus(4), grant tables, xbd(4), xennet(4))
in two parts: suspend and resume, and hook them to pmf(9).
- modify pmap so that Xen hypervisor does not cry out loud in case
it finds "unexpected" recursive memory mappings
- provide a sysctl(7), machdep.xen.suspend, to command suspend from
userland via powerd(8). Note: a suspend can only be handled correctly
when dom0 requested it, so provide a mechanism that will prevent
kernel to blindly validate user's commands

The code is still in experimental state, use at your own risk: restore
can corrupt backend communications rings; this can completely thrash
dom0 as it will loop at a high interrupt level trying to honor
all domU requests.

XXX PAE suspend does not work in amd64 currently, due to (yet again!)
page validation issues with hypervisor. Will fix.

XXX secondary CPUs are not suspended, I will write the handlers
in sync with cherry's Xen MP work.

Tested under i386 and amd64, bear in mind ring corruption though.

No build break expected, GENERICs and XEN* kernels should be fine.
./build.sh distribution still running. In any case: sorry if it does
break for you, contact me directly for reports.

forgot to reflect here.

Improvements in the attachement routines: in case of error, don't forget
to free() the allocated rings. Should not happen anyway, more a matter

- Upgrade suspend/resume code to comply with Xen2 removal.
- Add support for PAE domUs suspend/resume.
- Fix an issue regarding initialization of the xbd ring I/O that could end
badly during resume, with invalid block operations submitted to dom0 backend.

NetBSD supports PAE under x86_32 by considering the L2 page as being
4 pages long instead of 1.

Xen validates the page types during resume. Sadly, the hypervisor handles
alternative recursive mappings (== PG/PD entries pointing to pages other
than self) inadequately, which could lead to incorrect page pinning.

As a result, the important change with this patch is to clear these alternative
mappings during suspend, and reset them back to their former self upon
resume. For PAE, approx. all 4 PDIR_SLOT_PTEs could be considered as
alternative recursive mappings.

See comments in pmap.c for further details.

Now, let the testing and bug hunting begin.

Initial code for xen save/restore/migrate facilities.

- split the attach code of frontends in two half: one that is only needed
during autoconf(9) attach/detach phases, and one used at each save/restore
of device state (between suspend and resume).

Applies to hypervisor, xencons, xenbus, xbd, and xennet.

- add a rwlock(9) ("ptom_lock") to protect the different parts in the kernel
 that manipulate MFNs (which could change between a suspend and a resume,
without the kernel noticing it). Parts that require MFNs acquire a reader lock,
while suspend code will acquire a writer lock to ensure that no-other parts
in kernel still use MFNs.

- integrate the suspend code with sysmon.

- various things in pmap(9), and clock.

TODO:
- factorize code a bit more inside frontends drivers.
- remove all alternative recursive (APDP_PDE) mappings found in PD/PT during
suspend, as Xen does not support them.
- abstract the ptom_lock locking, it is only required when kernel preemption
is enabled, or on MP systems.

Current code works mostly. You may experience difficulties in some corner
cases (dom0 warnings about xennet interface errors, and Xen tools failing to
 validate NetBSD's alternative pmaps).

to NetBSD/Xen, both Dom0 and DomU.

Prepare for xenamd64:
- kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few
  #ifndef XEN)
- move some files that can be shared between i386 and amd64 from
  xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code)
- split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h
- use <xen/...> instead of <machine/...> for cpu-independant include files.

more work needed here, i386-specific files should got out of arch/xen to
arch/xeni386, and more code shared with arch/i386.

Add needed framework for backend drivers.
As we want some control on the name the backend driver will have we
can't use autoconf(9) here. Instead backend drivers registers to
xenbus, which will call a create callback when a new device is there.
Backend devices won't have a "struct device" in xenbus, use a void pointer
instead.

Apply patch (requested by bouyer in ticket #1245):
Pull up Xen3 domU support. This adds support for the Xen-3 memory bootstrap,
xenstore, and block and network device frontend. Xen-3 support is turned
on by 'options XEN3', which disable Xen-2 support.
Changes affecting non-xen3 specific code:
- xbd and xennet at hypervisor now attaches with xbd_hypervisor and
  xennet_hypervisor
- x86_atomic_* renamed to xen_atomic_*
- use genassim.cf to pull in more constant from include files for assembly
- Map the shared info page from locore.S instead of the 0xffffffff hack
  in xen_machdep.c
- remove some unused code
- some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline
- more debug code
