commands: move checkformat to bookmarks module commands.bookmark has grown quite large with two closures already. Let's split this up (and in the process allow extensions to override the default behavior).

tests: tell pip not to check for a newer version pip will check to see if it's the latest version, and complain if it isn't. The --no-index flag implies the --disable-pip-version-check flag, and makes the warning (and any associated network activity) go away.

changeset_templater: backport parts map of [templates] section from formatter

formatter: add support for parts map of [templates] section Unlike a mapfile whose template is looked up by spec -> mapfile -> topic, [templates] section is global. We use :sub-section syntax to define parts per template.

changeset_templater: backport separator template from formatter As commented, this should be used with docheader and docfooter, not with header nor footer. That's one reason why no props are passed to templater when rendering a separator. (See map-cmdline.changelog to understand what the "header" is.)

formatter: add support for separator template This seems useful for writing JSON template.

formatter: add support for docheader and docfooter templates templatepartsmap() is a minimal copy of changeset_templater.__init__(). I tried to factor out a common function, but it was unnecessarily complicated.

formatter: extract helper function to render template

changeset_templater: do not enable verbosity postfix for [templates] section Since this postfix hack exists only for backward compatibility, we don't need it for new [templates] section. This isn't a BC as templates defined in [templates] section weren't loaded until recently.

changeset_templater: simplify handling of verbosity postfix

merge with stable

tests: don't touch the network when using virtualenv

tests: removed ReportedTest exception The only call site called addFailure before raising, which is exactly what the failure exception handler does. So this complexity is not needed. We have test coverage of this "server failed to start" scenario and nothing appeared to change.

tests: remove support for warned tests The previous changeset removed the last caller of addWarn(). So, we rip out that method and all the code related to tracking warned tests in the results system. There was even a comment saying we may want to fold warned tests into the "failed" state, which is what the previous changeset did.

contrib: add check-code rule to enforce non-use of `python` in tests

cleanup: use $PYTHON to run python in many more tests Spotted one of these, then wrote a check-code rule that caught them all. It will be the next change.
