XML::Stream::ParseStream doesn't buffer partial tags

[topaz]

The documentation for this function claims:

# ParseStream - takes the incoming stream and makes sure that only full
#               XML tags gets passed to the parser.  If a full tag has not
#               read yet, then the Stream saves the incomplete part and
#               sends the rest to the parser.

However, it doesn't seem to have any of the described capability, even though the calling code (like in XML::Stream::OpenStream) seems to assume it works as described by blindly passing in data from the network.

A recent version of the Openfire server passes partial XML fragments over the network, at least when restarting a session after TLS and auth. XML::Stream::ParseStream receives "<" in one invocation, followed by "?xml ....." and the rest of the document in another invocation, confusing the parser.

So, XML::Stream::ParseStream needs to buffer partial XML documents until they're ready to be parsed, as described in its documentation.

This was fixed a while back in an as-yet unmerged pull request (#11). I'm going to rebase that one now as there have been changes upstream. Hopefully this will get merged into an upcoming release.
