* src/xend_internal.c: Added support for vnclisten parameter
in generated XML
* src/xml.c: Support new style paravirt framebuffer graphics
configuration from xen 3.0.4 tree. Also add support for setting
vncpasswd & vnclisten address SEXPR values, based on passwd
and listen XML attributes.
* tests/sexpr2xmltest.c: Whitespace cleanup.
* tests/xml2sexprtest.c: Added test cases for new style paravirt
framebuffer graphics configuration
* tests/xml2sexprdata/xml2sexpr-pv-vfb*: Data files for new
tests for graphics
* tests/sexpr2xmldata/sexpr2xml-pv-vfb-*.xml: Added listen address
attribute
