Add a variant of virXPathULong() which can handle long longs.

Needed for parsing storage device capacities.

Add new functions to allow parsing integers with base 16

This will be used to e.g. parse PCI vendor IDs.

It looks like these functions have never existed.

* src/qemu_conf.c src/qemu_conf.h src/xend_internal.c
  src/xend_internal.h src/xm_internal.c src/xml.c src/xml.h:
  Patch from Cole Robinson adding sound support for QEmu and Xen
* tests/qemuxml2argvtest.c tests/sexpr2xmltest.c
  tests/xmconfigtest.c tests/xml2sexprtest.c:
  Associated regression tests

Done using this command (also includes .c.in and .h.in files):
for i in $(g ls-files|grep -E '\.[ch](\.in)?$'|grep -v gnulib); do
  expand -i $i > j && mv j $i;done

  src/xen_unified.[ch] src/xend_internal.[ch] src/xml.[ch]: last
  patch for the library NUMA support, allow to serialize CPU pinning
  to domain configs (but won't work though proxy access), includes
  many patches from Saori Fukuta.

        * src/xend_internal.c, src/xml.c, src/xml.h: Properly check buffer
        size in virDomainXMLDevID (Hugh Brock).

  routines, only xml.c is cleaned up, other modules to follow.
Daniel

  src/sexpr.h src/test.c src/xm_internal.c src/xml.c src/xml.h:
  applied patch from Richard Jones adding check to printf-like
  functions and fixing the problems raised

  adding virConnectGetCapabilities(), plus various small little
  fixes

Daniel

        * src/xend_internal.c, src/xm_internal.c: pass the
        connection to virDomainParseXMLDesc()

        * src/xml.[ch]: make virDomainParseXMLDesc accept
        a virConnectPtr so that we can use it later to
        lookup the bridge associated with a network

        * tests/xml2sexprtest.c: just pass NULL here, it's
        safe

  intagrated patch from Michel Ponceau to add hot-plug devices
  support to the API, integrated in driver API and fixed
  a few small things. Still a TODO in src/xml.c about
  moving xenstore direct accesses to a new routine.

* include/libvirt.h include/libvirt.h.in: cleanup
* src/libvirt.c: remove debugging output
* src/xend_internal.c src/xml.c src/xml.h: reimplement
  virDomainGetXMLDesc() based on xend interface, now work as user too.
Daniel

* 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
