Adds "make deb", which does a "make dist" build and wraps the
resulting dist/install files in dist/xen-<version>.deb
This is _not_ a "packaged" version of Xen for Debian users, nor is it
intended to compete with anyone else's packaging efforts. In
particular it doesn't do any of the boot-time or fstab fixups needed
to actually start the xen tools. It's just a quick hack for
developers to be able to quickly install and uninstall a Xen build on
a test box.

A fair few things under tools link against libraries which they don't
even use.
Most of this appears to come from copy-and-pasting previous Makefile
snippets and cargo-culting plus the tendency to define global $(LIBS)
even for Makefiles which build multiple separate utilities or
libraries.
Identified by comparing a build with --as-needed to one without by
looking at the NEEDED header of all ELF objects.

Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

Fixed problems include:
* previously just print out a error instead of help info
while running without cmdline parameters.
* -u & -n lead to Segmentation fault.
* -c and then use default ranges, the default ranges is not
50us... but 50000/tsc2us....

Also fix some references to "struct xc_interface" which should have
been simply "xc_interface" in tools/xenpaging, and update QEMU_TAG to

This tool reads the CPU save records, overwrites RIP with a bogus
value, and then restores them. This is, of course, not guaranteed
to crash the guest (since the CPUs may not be executing in kernel
at the time) but it's good for breaking into some tight loops that
would be hard to debug otherwise.

According to Intel 64 and IA32 Architectures SDM 3B Appendix B, Intel
Nehalem/Westmere processors provide h/w MSR to report the core/package
cstate residencies.Extend sysctl_get_pmstat interface to pass the
core/package cstate residencies, and modify xenpm to output those

Now the init script is called xencommons and, as the name suggests, it
is a common script between xl and xend because it is used to start
xenconsoled, xenstored and xenbackendd and the initialization of these
three daemons has been removed from xend. The global
xen_toolstack=xl/xend variable has been removed. Regarding the
network setup, I made the vif scripts follow the same pattern as the
other scripts in xen-backend: a new script called vif-setup is
executed unconditionally. vif-setup is going to do the right thing
depending on the value of the environmental variable "script" (same
technique used before), defaulting to vif-bridge. In the common
scenario the toolstack doesn't need to set the variable "script"
because vif-bridge is going to be called anyway. There is no global
network script to setup the network bridges with xl, so if you are
using xl without xend, you need to manually configure the bridges
using your distro network setup, or, if you are lazy, you can just add
something like:
/etc/xen/scripts/network-bridge start
to your rc.local.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

Add "page deduplication" capability (with optional compression
and trailing-zero elimination) to Xen's tmem.
(Transparent to tmem-enabled guests.) Ephemeral pages
that have the exact same content are "combined" so that only
one page frame is needed. Since ephemeral pages are essentially
read-only, no C-O-W (and thus no equivalent of swapping) is
necessary. Deduplication can be combined with compression
or "trailing zero elimination" for even more space savings.

F12 introduces a tool to automatically report bugs when there are core
dumps. Since xen-detect relies on fork+waitpid in order to trap a
SIGILL from a child, every time someone runs xen-detect on a bare
metal kernel a bug is reported into Red Hat's Bugzilla. :-)
However, even without this contingent need, leaving core dumps around
is not nice. So this patch just traps SIGILL using
signal/sentjmp/longjmp, without the need to fork.

pygrub currently has a hardcoded path of /usr/bin/python which is not
correct if the version of python at install time is not the same as
that at build time. This patch uses the existing install-wrap and
python/get-path machinery.
(It does not address the currently-existing bug that the get-path
machinery works by assuming that `python' is a symlink, rather than
querying the python interpreter for its version.)
