commit e36239d09f5b5bc807cb073eaab0a2b7f7f9a9ef
Author: Richard W.M. Jones <rjones at redhat.com>
Date:   Fri Dec 12 14:44:54 2014 +0000

    New API: guestfs_c_pointer
    
    This returns the C pointer to the guestfs_h handle (ie. guestfs_h *).
    
    The purpose of this API is to interwork with other non-C libraries.
    See RHBZ#1075164 for the rationale when applied to another library.
    
    (cherry picked from commit d8c43d556b45f4c9676fdbfce0e9fe07b709635a)
