ubuntu-wily: add makefile rule to build deb

make: turn ubuntu docker into template This allows us to easily add more ubuntu docker targets (which following patches will do). Also, we no longer need the mkdir command.

revsets: add docs for '%' operator

graft: fix printing of --continue command Properly shell quote arguments, to avoid printing commands that won't work when run literally. For example, a date string with timestamp needs to be quoted: --date '1456953053 28800'

hghave: remove unused check for bdist_mpkg

osx: create a modern package including manpages Instead of using bdist_mpkg, we use the modern Apple-provided tools to build an OS X Installer package directly. This has several advantages: * Avoids bdist_mpkg which seems to be barely maintained and is hard to use. * Creates a single unified .pkg instead of a .mpkg. * The package we produce is in the modern, single-file format instead of a directory bundle that we have to zip up for download. In addition, this way of building the package now correctly: * Installs the manpages, bringing the `make osx`-generated package in line with the official Mac packages we publish on the website. * Installs files with the correct permissions instead of encoding the UID of the user who happened to build the package. Thanks to Augie for updating the test expectations.

hghave: add check for OS X packaging tools

tests: add test for Mac OS X package construction

osx: add support for keeping mpkgs This is a bit of a hack, but I don't really want to mount a dmg during a test, and I don't see an option with hdiutil to take a dmg and spit out a folder, so this is what we've got for now.

osx: add support for dumping built dmg into OUTPUTDIR
