- the Makefile installs the ACM security-related tools
into /etc/xen/acm-security
- improves and cleans up some of the tools
- updates the documentation

This patch moves the pincpu op back to where it was.

regardless of the outcome of the select call, and then failing because the
socket is non-blocking.
SocketClientConnection, SocketConnector, TCPClientConnection, TCPConnector,
connectTCP, UnixClientConnection, UnixConnector, connectUnix have gone.
loseConnection and stopListening and closeSocket (where they are needed) are
now called close. startListening is now called listen.

version compiles and starts up, but I'm not really sure how to test the new
xenbus implementation.
* Added unbind_evtchn
* Copied parts of the Linux spinlock implementation to make the changes to
xenbus compared to Linux smaller. Also added a dummy rwsem implementation.
* Updated the xenbus-files

Otherwise, when destroying the domain, if the current sl2 is unpinned
then the shadow page will be freed without accquire the shadow_lock.
This may also improve the performance due to avoiding uncessary
unshadow.

destroy an OS when it is in real mode, there is an extra put_page in
domain_relinquish_resource. This causes the page be freed with
non-zero type count. With ASSERT enabled, hypervisor will crash; with
debug=n, on some machines, the system will hang in
alloc_domheap_pages, due to type_info being a union with cpumask and
not equal to 0.

about to be freed up by the system after a domain destruction (i.e. the memory
is being scrubbed asynchronously, and will be released soon).

remove and recreate the /local directory, but the manual_node call only works
if the tdb is empty -- we must use create_node, otherwise the store is
corrupted.
It's not clear to me that the other manual_node calls are safe, but I have only
made this smaller change for the sake of stability. These other calls should
be reviewed.

I've changed this to only write "backend" (xenbus_backend.root) into
XENBUS_BASE_PATH. After appending XENBUS_TYPE (also exported) you can
construct the "base path" easily in the scripts. I've completely
removed writing XENBUS_FRONTEND_ID in favour of reading it from the
store at "$XENBUS_PATH/frontend-id".
Avoid re-reading the store over and over for the frontend domain's vm-path.
The patch also fixes a memory leak in backend_bus_id where we
leak the memory referenced by frontend if the function succeeds.
