src: utils: add verdict2str and use it

Add verdict2str() and str2verdict() helper functions and use in XML.

While at it, I've fixed a small style issue in the data_reg JSON output and
a bug in the data_reg XML parser: The parser walked the top level tree,
instead of single <data_reg> node. Introduced in (51370f0 src: add support
for XML parsing).
