res_pjsip_pidf_eyebeam_body_supplement: Correct status presentation

This change fixes PIDF content generation when the underlying device
state is considered in use. Previously it was incorrectly marked
as closed meaning they were offline/unavailable. The code now
correctly marks them as open.

Additionally:

  * Generate an XML element for our activity instead of a using a text
    node.

  * Consider every extension state other than "unavailable" to be 'open'
    status.

  * Update the XML namespaces and structure to reflect those
    documented in RFC 4480

  * Use 'on-the-phone' (defined in RFC 4880) instead of 'busy' as the
    "in use" activity. This change results in eyeBeam using the
    appropriate icon for the watched user.

This was tested on eyeBeam 1.5.20.2 build 59030 on Windows.
