hghave: add "chg" flag to skip tests that can't be compatible with chg Several tests fail with chg for several reasons such as loaded chgserver extension, running uisetup() per server instead of per runcommand, etc. Since these tests can't/shouldn't be changed to be chg friendly, we need a flag to skip them. This patch explicitly drops CHGHG environment if chg isn't involved. This way, hghave can just check if CHGHG exists.

tests: add new test for #! shebang lines * use #!/bin/sh not e.g. #!/usr/bin/sh * use #!/usr/bin/env python not e.g. #!/usr/bin/python

largefiles: introduce push --lfrev to control which revisions are pushed The default of pushing all largefiles referenced in outgoing revisions is safe, but also expensive and sometimes not what is needed. We thus introduce a --lfrev option, similar to what pull already has. By specifying an empty set of revisions (or null), it is possible to get lazy (and insecure!) pushes of revisions without referenced largefiles, similar to how pull works.

largefiles: don't access repo.changelog directly in getlfilestoupload Make it possible to pass both nodes and revisions to getlfilestoupload.
