because entry.S includes syscall_table.S but it's in the wrong
directory. This simply adds the obj-dir to the include search path.

- include grant table includes from common.h rather than blkback.c,
since both C files use grant tables
- include linux/version.h from block.h (a macro there uses it)
- include asm-xen/hypervisor.h from block.h (virt_to_machine)

over to using xenstore for triggers. Dropping the control messages also
fixes the issue with not being able to use xm vcpu-hotplug on dom0.

of codes for signaling a shutdown request.
Also, we fix the return code for the shutdown notifier, so other
notifiers will get to run ;)

1. Converts the shutdown driver and xend to use the store instead of
control messages,
2. Includes Anthony's xenstore notification code, and
3. Changes xend so that sysrq's are no longer sent as "special case"
shutdown messages. Store keys are cheap, so making the sysrq
delivery less obscure is good.
I think I have made all of the appropriate modifications to Xend, but
it is complex, so I may have missed something. Comments are welcome.

This patch changes the blktap code mapping pages to user space to be
faster and to allow page lookups to foreign mapped pages through linux
to do direct io. An AIO test driver on this achieves comparable
performance to the in-kernel block-backend.

allows them to be used in situations where the IRQ subsystem is
not paravirtualised.

xenstore instead of control messages.
Note: Because there is no way to set a watch on a non-existent key,
this patch includes a workaround to account for the fact that dom0's
store keys are not initialized by the tools before it boots.

frame_and_sectors field in blkif messages, to eliminate the
"magic shifts" in the blkif code.
It also increases the number of bits representing the sector
number within a page, from 3 to 5, to allow page sizes up to
16K (needed for IA64).
Tested to still work on x86.
