obslog: make changeset available to templater obslog templating currently has very limited support for templating the precursor changeset (when available). The only available keywords are {node}, {rev}, and {shortdescription}. This patch makes the entire changeset available to the templater by passing it to formatter.context(). That function has been available since Mercurial 4.2.

tests: simplify by pruning unwanted changesets a little earlier The pruned commits are not relevant to the test case, so let's clean them up at the end of the previous test case instead of part-way through the next one.

evolve: use more often seen metavariables in command synopsis strings Also use ellipsis when multiple options are acceptable.

topic: add more options to command synopsis string

debian: also build with python3 We build with Python 3 along with Python 2. The binary package will contain the extension for both python version. This is to ease transition until the mercurial package in Debian uses Python 3. The documentation is still built with Python 2 because it needs Mercurial (which is currently Python 2).

debian: update debhelper compat Level before 9 are deprecated says debhelper 12. Upgrade to 10, which is available in Debian oldstable and old Ubuntu releases to be conservative (and since we probably don't need more).
