[libvirt] [PATCH v4 0/2] Add support for multiple serial ports into the Xen driver

[Michal Novotny]

Hi,
this is the patch to add support for multiple serial ports to the
libvirt Xen driver. It support both old style (serial = "pty") and
new style (serial = [ "/dev/ttyS0", "/dev/ttyS1" ]) definition and
tests for xml2sexpr, sexpr2xml and xmconfig have been added as well.

Written and tested on RHEL-5 Xen dom0 and working as designed but
the Xen version have to have patch for RHBZ #614004 but this patch
is for upstream version of libvirt.

Also, this patch is addressing issue described in RHBZ #670789.

Differences between v2 and v3:
 * Fixed serial port handling if we have definition of device in non-zero port number
 * Added second test for first port undefined (i.e. port value > 0 for just one
   serial port)

This between v3 and v4 (this one):
 * Traversal lookup to ensure the right order of the serial ports has
   been implemented
 * Parsing and finding new available port number for parallel port has
   been added as well
