[libsoupmm] Fix Message ctor, Add XML-RPC support

[Siavash Safi <siavashs src gnome org>]

commit 502ebab98ea852195955146a1b48b349ed05d56b
Author: Siavash Safi <siavash siavashs org>
Date:   Mon Aug 31 18:48:56 2009 +0430

    Fix Message ctor, Add XML-RPC support
    
    * .gitignore:
    * codegen/m4/convert_libsoup.m4:
    * libsoup/libsoupmm/filelist.am:
    * libsoup/libsoupmm/xmlrpc.cc:
    * libsoup/libsoupmm/xmlrpc.h:
    * libsoup/src/message.ccg:
    * libsoup/src/message.hg: Removed the default ctor since there's no
    property to set the uri string directly.
    Hand coded create() since the default ctor is removed. We create a URI
    from the uri string and pass it to the other create function(similar to
    what the C API does).
    Add create_xmlrpc_request() to create a Message wich contains an XML-RPC
    request.
    Add "got-chunk" signal.
    * libsoup/src/uri.ccg:
    * libsoup/src/uri.hg: Rename the ctor argument.
