There was a recent report of the xen-xl converter not handling config files missing an ending newline
https://www.redhat.com/archives/libvir-list/2017-October/msg01353.html Commit 3cc2a9e0 fixed a similar problem when parsing content of a file but missed parsing in-memory content. But AFAICT, the better fix is to properly set the end of the content when initializing the virConfParserCtxt in virConfParse(). This commit reverts the part of 3cc2a9e0 that appends a newline to files missing it, and fixes setting the end of content when initializing virConfParserCtxt.
