Add a --hugetlbfs commandline option to give a path to hugetlbfs-map guest
memory (down in kvm__arch_init()). For x86, guest memory is a normal
ANON mmap() if this option is not provided, otherwise a hugetlbfs mmap.
This maps directly from a hugetlbfs temp file rather than using something
like MADV_HUGEPAGES so that, if the user asks for hugepages, we definitely
are using hugepages. (This is particularly useful for architectures that
don't yet support KVM without hugepages, so we definitely need to use
them for the whole of guest RAM.)

This patch removes the alphabetical sorting from util/generate-cmdlist.h so
that 'kvm run' command, for example, is displayed first:
$ ./kvm
usage: kvm [--version] [--help] COMMAND [ARGS]
The most commonly used kvm commands are:
run Start the virtual machine
pause Pause/resume the virtual machine
version Print the version of the kernel tree kvm tools
list Print a list of running instances on the host.
debug Print debug information from a running instance
balloon Inflate or deflate the virtio balloon
See 'kvm help COMMAND' for more information on a specific command.

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.

Some kernel parameters are convenient if passed in
hex form so our options parser should handle even
such form of input.

Augmentation is started on the pre-rotation node found in the search,
augment the rotated node instead.
Max high is the max of max highs below it, not the max of highs below it.

Interval rb-tree allows to directly store interval ranges
and quickly lookup an overlap with a single point or a range.
The helper is based on the kernel rb-tree implementation
(located in <linux/rbtree.h>) which alows for the augmention
of the classical rb-tree to be used as an interval tree.

We can use this script to create/delete a private bridge,
and launch a dhcp server on the bridge by dnsmasq,
setup forware rule of iptable, then guest can access public network.

- 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.
