This patch adds 'kvm sandbox' which is a wrapper on top of 'kvm run' which
allows the user to easily specify sandboxed command to run in a custom
rootfs guest.
Example usage:
kvm sandbox -d test_guest -k some_kernel -- do_something_in_guest

This patch implements 'kvm setup' command that can be used to setup a guest
filesystem that shares system libraries and binaries from host filesystem in
read-only mode.
You can setup a new shared rootfs guest with:
./kvm setup -n default
and launch it with:
./kvm run --9p /,hostfs -p "init=virt/init" -d ~/.kvm-tools/default/
We want to teach 'kvm run' to be able to launch guest filesystems by name in
the future. Furthermore, 'kvm run' should setup a 'default' filesystem and use
it by default unless the user specifies otherwise.

This patch adds 'kvm stat' command that allows retrieving statistics out of
a running guest.
Currently the only supported statistics are memory statistics, available using the
'--memory' parameter.

This patch seperates 'kvm pause' into 'kvm pause' and 'kvm resume',
'kvm pause' no longer acts as a switch between running and paused state but
instead just switches the instance into paused and reume is handled by
the new 'kvm resume'.

Add a 'kvm version' command which prints the version of the kernel
used to build kvm tools.
Part of the code is based on and was loaned from perf.

This patch adds a 'kvm debug' command that's currently an alias for
kill -USR2 `pidof kvm`
Which pauses a guest (freezes all VCPU threads) or resumes a paused
guest.

Useful for debugging. It adds "--debug" option as well so
debug prints are seen only if user asked for them.

- The Documentation/ directory will have a text file for each commmand. The
text file should contain the information about the command in manpage format.
- command-list.txt: is a list of common commands used with the kvm tool.
- util/generate-cmdlist.sh: is a shell script that uses command-list.txt and
text files in Documentation/ directory to generate the common-cmds.h file in
the include directory. The header file is furthur used to display a usage
messgae. Almost the entire script is copied from the tools/perf.
