Subject: ctf: make parseMetadataStream() output the metadata version
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=414988087168a1404e035c000d498f08a903f66a;p=babeltrace.git

ctf: make parseMetadataStream() output the metadata version

Add a `metadataVersion` field to `ParseRet`, allowing users of this
class to know the metadata version, after successfully parsing a
metadata file.
