It has been pointed out that the wording of the license of this library is
not entirely clear.
The term "dual licensing" usually refers to a licence choice of two
licenses "LICENSE1 _or_ LICENSE2.
Instead the license of this library claimed "LICENSE1 _and_ LICENSE2".
After an internal discussion with @metajack and @pasis it was made clear
that the initial idea was to dual license the library in the usual way.
This was also made clear by jack on the ML in the past [0].
As of jack, these licensing terms originated from jquery, which also used
the 'and' version in the past and has since been corrected [1].
This patch changes the license terms to 'MIT or GPLv3' and also adds SPDX
headers [2].

... to provide an easier way to find long paths.
After looking at some code in profanity-im/profanity#1605 I thought this
could help to make libstrophe-user code easier to write (and read).
Initially it started off as `xmpp_stanza_get_child_by_xpath()` but then
I was annoyed when it came to handling all those potential corner cases
like e.g. escaping URL's in the ns ... so here we go with a
vararg approach :)

If parser has an unfinished stanza with depth > 1, it can happen that
parser->stanza points to a child. Releasing the child doesn't free the
parent stanza.
Instead of releasing parser->stanza in parser_reset() and parser_free(),
find the top most parent and release the whole tree. Also add a test
case for this memory leak.
This function creates a stanza object from a string. The string must
contain a single complete stanza. Multiple stanzas will lead to memory
leak and this is not handled in the patch.
