Right now, the memory for the 1:1 physical mode page tables comes from the
VMX domain's memory. With this change, when the user asks for a domain with
M Megabytes of memory, we actually allocate M+N megabytes in xend, where
N is the memory for the page table pages.
This simplifies the code in the device models that maps guest memory (we
now map all of it) and the E820 map can also give the full M megabytes to
the guest.

Description: use DESTDIR correctly
Standard makefiles always attempt to install to the root(/). Setting
DESTDIR is the normal way to install to an alternative location.
Setting prefix has the possibility of breaking programs, as the prefix
may have been embedded inside a compiled binary.

Support for USB virtualisation. Adds the USB frontend / backend, update build options,
make the control tools understand USB interfaces.
One extra file from vanilla Linux is imported (linux-2.4.28-xen-sparse/drivers/usb/hcd.c)
because small changes were required to make XenU domains build with a USB frontend. This
will not be required for the revised host controller infrastructure in Linux 2.6.
To use this, set "usb = " a list of USB ports in the domain config file. Ports are
specified as a path, e.g. '1' = the first USB port on the host, '1/2' is the second port
on the hub on the first host port, etc.
Should work for most mass storage and isochronous devices. May work for some HID devices
but these are not as intelligent and may have trouble supporting virtualisation.
Add an optional parameter (vcpus) to the xc_linux_build function replacing
the getenv() previously used and removing the requirement of using maxcpus
kernel parameter to limit the number of virtual cpus a guest uses. The value
can now be controlled in the domain configuration files.
The default value of 1 is set in XenDomainInfo.py but is overridden by
parsing the config value.

Symptom:
When using a udev-based dom0, if you try to create a domU with a virtual
sda device and you do not have a local scsi device xm create fails.
Fix:
When using udev, only the device nodes needed are made. The follow
patch changes Xend to return a device number based on:
http://www.lanana.org/docs/device-list/devices.txt
For sd and hd devices if stat() fails. It was tested against both 2.0.2
and 2.0.3.

Solve hang at net frontend initialization by necessarily passing domain ID to NetDev in xend.
This follows Andy's cset to support backends in unprivileged domains.
Better fix for popen. Also makes it easier to log stderr output
from popen'd commands, which we previously threw away. For now,
I'm also throwing it away.
Clean up public XenLinux header files. Now accessible from userspace as
#include <xen/linux...>
Got rid of the linux-xen-sparse symlink as it's no longer needed.
A coven of new wizards for Xensv (please test). Some of this might
need refactoring but it should make the web interface more useful.
also: misc version updates, some extra docs stuff.
