Joe Orton says:

This patch is a first pass at making util_xml.c independent of mod_dav:

* Rename dav_* to ap_xml_* for exported interface
* Remove dav_* from private functions
* Move text_header handling in from dav/main/util.c
* Move XML tree -> text conversion in
* Add include/util_xml.h header from parts of mod_dav.h
