* configure.in src/Makefile.am: adding dependency to libxml2

* include/libvirt.h* src/libvirt.c src/xend_internal.[ch]
  src/xml.[ch]: added XML parsing for Xen domain descriptions
  needed for creates, plugged in a converter to s-exp and
  xend call. Modified the virDomainCreateLinux() to reflect
  that XML based description. Seems to work.
* python/tests/create.py: added a test case which seems to work
  not tested much yet
* docs/*: regenerated
