Function virParseURI was added. This function is wrapper around
xmlParseURI. In this wrapper we are fixing what doesn't seems to be
fixed in libxml2 in the near future. The wrapper is written in such
way that if anything gets fixed in libxml2, it'll still work.
File changes:
- src/util/xml.h -- declaration
- src/util/xml.c -- definition
- src/libvirt_private.syms -- symbol export
- all others -- function call fixed and include added
