bundle1: fix bundle1-denied reporting for push over ssh Changeset b288fb2724bf introduced a config option to have the server deny push using bundle1. The original protocol has not really be design to allow such kind of error reporting so some hack was used. It turned the hack only works on HTTP and that ssh wire peer hangs forever when the same hack is used. After further digging, there is no way to report the error in a unified way. Using 'ooberror' freeze ssh and raising 'Abort' makes HTTP return a HTTP500 without further details. So with sadness we implement a version that dispatch according to the protocol used. We also add a test for pushing over ssh to make sure we won't regress in the future. That test show that the hint is missing, this is another bug fixed in the next changeset.

bundle2: keep hint close to the primary message when remote abort The remote hint message was ignored when reporting the remote error and passed to the local generic abort error. I think I might initially have tried to avoid reimplementing logic controlling the hint display depending of the verbosity level. However, first, there does not seems to have such verbosity related logic and second the resulting was wrong as the primary error and the hint were split apart. We now properly print the hint as remote output.

misc: update year in copyright lines This patch also makes some expected output lines in tests glob-ed for persistence of them. BTW, files below aren't yet changed in 2017, but this patch also updates copyright of them, because: - mercurial/help/hg.1.txt almost all of "man hg" output comes from online help of hg command, and is already changed in 2017 - mercurial/help/hgignore.5.txt - mercurial/help/hgrc.5 "copyright 2005-201X Matt Mackall" in them mentions about copyright of Mercurial itself

localrepo: avoid unnecessary sorting headrevs output already sorted, no need to sort it again.
