The virq triggers a scan for domains which have gone away, and then
removes those domains.

vmx_platform.c/inst_copy_from_guest() now uses vmx_copy. Also shored up
vmx_copy to handle copies when paging is enabled and improved its error
handling.

- page is moved next to store/console pages -- these are never put in the
free page pool by the domain
- xen_start_info is now a pointer to the original page instead of the copy

Mostly this makes the tap code work again with all of the changes that
have happened to the block drivers recently. We now use a shared page
per VBD (to the driver), and handle control information through the
store. The taplib interfaces have changed to be based around per-vbd
data structures that you can attach arbitrary handlers for.
There is also initial code for a user-level blockback driver, which
aims to get around the use of loopbacks for file-based vbds. Still
plenty of work to do here -- this is a working incremental checkin and
I'm away from this for the next four weeks.

- unbind/bind console evtchn

Also add simple read/write/rm clients for command line access to the
store (using the xenbus_dev store connection).

The driver exports xs_talkv to user-space, allowing programs running in
the domain to use the kernel's xenbus connection. Intended use is driver
domain device configuration where the driver domain is not the domain
running xenstored.

mechanism provides richer I/O operation semantics, such as and,or,xor
operation on MMIO space. This is necessary for operating systems such
as Windows XP and Windows 2003.
This is the first part of a two part patch. This patch applies to ioemu.
