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 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'.

Which pauses a guest (freezes all VCPU threads) or resumes a paused

This patch fixes code style issues pointed out by scripts/checkpatch. However,
some reported errors are false positives. In particular, the warning:
WARNING: line over 80 characters
is too strict for our code and thus needs to action to be taken.

- kvm-cmd.h: Adds a new structure cmd_struct to create a table of commands
and callback function. The structure was copied from tools/perf
- kvm-cmd.c: implements two main functions for command processing.
kvm_get_command(): searches table for specific command.
handle_command(): invokes the callback function for a given command.
- kvm-help.[ch] Implements the kvm help command. The function
list_common_cmds_help() is a copy of similar function in tools/perf.
