[Libguestfs] [PATCH] Add support for Windows dynamic disks (libldm / ldmtool).

[Richard W.M. Jones]

This is just an initial version of the patch, not to be
applied.  It implements just the diskgroup functions, ie.
corresponding to these ldmtool commands:

* ldmtool scan
* ldmtool show diskgroup <guid>

I have chosen yajl as the JSON parsing library (don't worry,
this is optional).  You will also, of course, need ldmtool
which is not packaged in anything except Fedora.

Rich.
