block inside accept rather than using select to poll and then calling accept
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.
Closes bug #379.

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.

Sleep for a configurable amount of time between xm create calls (by default,
5 seconds). This spaces out the booting of the new domains, meaning that they
should not thrash the disk so much.

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.

This removes the duplicated vcpus entries in the domain's sxpr.
