The Xen tools contain a number of Python extensions written in C. The
C API to Python, used by these extensions, is not stable from one
version of Python to the next.
Our build system uses whatever version of Python is the default on the
build system at that time to build these extensions. However, the
actual scripts such as `xm' use #!/usr/bin/env python which uses
whichever version of Python is the default on the deployment system at
the time of invocation.
If for any reason these two versions of Python are not the same (eg,
because the system is built on one computer and executed on another,
or because the system's gains a more recent Python installation
alongside the original which changes the previous default), warnings
and failures occur.
In this patch I arrange for Python scripts to be installed via a
special wrapper around `install', which determines the build-time
Python version and path and then writes that into the #! line at the
point of `make install' (or `make dist'). (It can also be overridden
by setting PYTHON_PATH.)

lomount is a tool which reads and parses a partition table in a disk
image block device and then uses mount -o ...offset=... to mount it.
This is not an ideal approach. For example, if the intended
filesystem has corrupted metadata the kernel's filesystem driver may
start to write outside of the intended region. This might even be
exploitable in some perverse circumstances.
Nowadays people wanting to do this should use kpartx, which uses
devmapper to create appropriate range mappings. So lomount should be
disabled.
miniterm may well be useful but it is a clone-and-hack of an upstream
project and is currently built but not installed by default, partly
because it doesn't make sense to install on the dom0 which it might be
trying to debug.
It is probably useful to retain these two programs in the source tree
but IMO they should no longer be built by default.
The attached patch does these things:
* CONFIG_LOMOUNT and CONFIG_MINITERM in Config.mk
can enable and disable these programs
* They are disabled by default
* If CONFIG_MINITERM=y it is still built but not installed.
make -C tools/misc/miniterm install will install it.

It predates the current shadow architecture and only performs an explicitly
invalid shadow operation (on itself).

advantage that the temporary path manipulation cannot affect the main script,
and that it can be shared with other programs, such as xm-test.

correct tool to use for hardware perfctr monitoring now.
Also remove unused xc_msr MSR accessor functions from libxenctrl.

* Move .PHONY directives next to targets,
this makes them a lot harder to miss
* Add missing .PHONY directives
* Remove nonexistent .PHONY directives
* Hopefully I didn'T miss anything...

Nothing but vnet uses libxutil -- move it there.
Makefile, xc.c, setup.py, configure, configure.in, Makefile.in:
This doesn't use libxutil.
Makefile, Makefile.vnet, Rules.mk:
Move libxutil into vnet since it's only used there.
Many files:
mvdir
Added the mbootpack tool, which packages multiboot boot files and
disguises them as a linux bzImage. Useful for booting Xen using
pxelinux, or another linux-only bootloader.

[PATCH] add-build.patch
Add build targets to all makefiles. Debian does builds as non-root, so
it's better to do as much as possible before requiring root privs.

Name: tools-misc-TARGETS.patch
Description: Split compile/link stages
distcc behaves much better when you compile and link in 2 separate steps.
Plus, this is a more standard way of doing things.

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.

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.
