New module: libguestfs bindings

[Richard W.M. Jones-2]

This might be of interest to members of this list.  I wrote a FUSE
module to provide access to libguestfs (http://libguestfs.org/).

When the module is more complete it should allow you to open up and
look inside the filesystem of a virtual machine, or any disk image
that you have.

At the moment it works for basic directory navigation, and I'm hoping
to complete the implementation of file read/write today.

Early patches posted here:

I pushed an early, read-only version of the libguestfs FUSE code here.
It's my first and only FUSE filesystem.  It seems to work well with
both command line tools and graphical programs like Nautilus.  If
anyone has any comments on the code, that would be helpful:
