This commit makes the semi-independent hivex library into a
separate upstream project. The git repo for hivex is now:
http://git.annexia.org/?p=hivex.git;a=summary
Downloads of hivex are available here:
http://libguestfs.org/download/
All questions, patches, bugs etc should be sent to the libguestfs
mailing list and bug tracker.

Previously this caused a serious performance regression,
but we believe this is now fixed:

This commit is not of general interest. It contains the tools which
I used to reverse engineer the hive format and to test changes.
Keeping these with the rest of the code is useful in case in future
we encounter a hive file that we fail to modify.
Note that the tools are not compiled by default. You have to compile
each explicitly with:
make -C hivex/tools <toolname>.opt
You will also need ocaml-extlib-devel and ocaml-bitstring-devel.

On some combination of installing, upgrading and removing the base
libguestfs package on x86_64, multilib can corrupt libguestfs by
leaving a copy of /usr/bin/libguestfs-supermin-helper around which
references the wrong architecture (usually, contains links to the
i386-based appliance, when the x86_64 appliance should be constructed).
This commit changes libguestfs-supermin-helper so that the script is
the same on all architectures. Instead, the library passes the
differences to the script (eg. $host_cpu). Because the i386 and
x86_64 libraries should be at different locations (/usr/lib vs
/usr/lib64) this should prevent multilib from screwing things up.

This commit combines the previously separate "inspector_generator.ml"
program which generated bindings for virt-inspector.
Having two separate programs caused no end of troubles for developers,
so we now combine them into a single program.
NOTE: OCaml xml-light is now *required* in order to rebuild the
generated code.

The following 3 summary messages in the configure output
always displayed "yes" even if they were not actually
enabled.
Haskell bindings .................... yes
virt-inspector ...................... yes
virt-* tools ........................ yes
Fixed by correcting the code that tests if the automake
conditional is set.

This implements FUSE filesystem support so that any libguestfs-
accessible disk image can be mounted as a local filesystem.
Note: file writes (ie. write(2) system call) is not yet implemented.
The API needs more test coverage, particularly lesser-used system
calls.
The big unresolved issue is UID/GID mapping between guest filesystem
IDs and the host. It's not easy to automate this because you need
extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).

config.status touches make.sh each time it runs, even if the
resulting script would not change. This causes the appliance
to get rebuilt much more frequently than is necessary.
There's no way to stop configure running, but we can move the
config.status command into a Makefile rule to stop this
undesirable behaviour.

In hivex/: This mini-library allows us to extract Windows
Registry binary files ("hives").
There are also two tools: hivexml converts a hive to a
self-describing XML format. hivexget can be used to extract
single subkeys from a hive.
New tool: virt-win-reg. This is a wrapper around the library
functionality allowing you to pull out data from the registries
of Windows guests.

This moves the tool programs into a single directory:
cat/* -> tools/virt-cat
df/* -> tools/virt-df
edit/* -> tools/virt-edit
rescue/* -> tools/virt-rescue
This in itself simplifies the build process because we only need
one Makefile and one copy of 'run-locally'.
'run-*-locally' has become just 'run-locally' and takes an extra
parameter which is the name of the tool, eg:
run-locally cat [virt-cat params...]
virt-inspector stays in its own directory, because this contains
more than just a single Perl script.

This commit adds a generic mechanism for deriving language bindings
for virt-inspector, and implements one concrete binding, for OCaml.
The bindings are generated from the RELAX NG schema (virt-inspector.rng)
which is supposed to be a correct and always up to date description
of the XML that the virt-inspector program can generate.
From the RNG we generate a set of types to describe the output of
virt-inspector for the language, plus an XML parser, plus some
glue code to actually run an external instance of virt-inspector
and parse the resulting XML.
At runtime, an external 'virt-inspector --xml <name>' command runs
and the XML is parsed into language-specific structures.
This has been tested on the four example files (inspector/example?.xml)
The only particular difficulty about the OCaml binding is the use of
Obj.magic, which is naughty but works because of the isomorphism
between the representation of tuples and records in OCaml. This
seems to cause no problems in my test program. Apart from this, the
OCaml binding is straightforward and could be adapted easily for any
other languages that want type-safe virt-inspector bindings.
It's important to keep virt-inspector.rng up to date with changes
to virt-inspector's XML output format.

This is an example of how to write an app which uses libguestfs
and libvirt, and has a responsive user interface (using threads).
It is a Gtk-based "graphical virt-df".
Read the top of the 'viewer.ml' file first for instructions on
how to compile. This program is not compiled by default.

Edit any file in a guest. This was possibly previously
using guestfish, but having a separate command makes it
simpler.
The usage is simply:
virt-edit mydomain /some/file
It runs $EDITOR or vi on the file, and if the user changes
it, uploads the result back to the VM.

This command runs a "rescue appliance" against a virtual machine
or disk image. This is useful for making ad-hoc interactive
changes to virtual machines.
$ virt-rescue --ro /dev/vg_trick/F11x64
Welcome to virt-rescue, the libguestfs rescue shell.
Note: The contents of / are the rescue appliance.
You have to mount the guest's partitions under /sysroot
before you will be able to examine them.

vmchannel is no longer required, so we shouldn't test for it.
However we should test instead for user mode networking support.
Also fix up the documentation / error messages.
Always test for vmchannel and user mode networking support in
qemu. This gives us more troubleshooting information if people
report bugs.

Add the configure parameter --enable-packet-dump so that this
code can be enabled without editing the source.
This code is normally commented out, because it is too verbose
unless you happen to be debugging the underlying protocol. Because
it is normally commented out, I found it had bit-rotted slightly.
This commit also fixes the obvious problems.
