presence_xml: implementation of pv $xml(...)

- handling of xml docs using xpath
- $xml(name=>doc) - get/set an xml doc under 'name'
- $xml(name=>xpath:xpath-expression) - evaluate/update xpath extension
- example:
	$xml(x=>doc) = '<?xml version="1.0" encoding="UTF-8"?><a><b>test</b></a>';
	xlog("content of node b: $xml(a=>xpath:/a/b/text())\n");
	$xml(a=>xpath:/a/b) = "1234";

- TODO list:
	- extend presence modules to work also with xml documents from $xml() PV
	- support to set node content to an xml tree

- usage:
	- do routing decisions based on content of xml documents comming
	  with SIP messages (such as PUBLISH)
	- update xml document content
	- evaluate XPath-allowed expressions and functions, see:
		http://www.w3.org/TR/xpath
