inspector: Generate language bindings for OCaml.
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.

New tool: virt-edit
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.

Add 'virt-rescue' command.
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.

Add direct appliance mode flag and implementation.
When the g->direct flag is set, the appliance stdin/stdout
are not connected to the library. Instead they inherit the
stdin/stdout of the caller.
This is used to implement virt-rescue.

Tidy up appliance rescue code.
The appliance shouldn't run the daemon after we leave the
rescue shell. It should just exit instead.

Rejig configure.ac tests for qemu vmchannel support.
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.
