lfs: enable the extension locally after converting to an 'lfs' repo This is consistent with clone and share in the previous commits.

lfs: enable the extension locally after sharing a repo with 'lfs' requirement This is consistent with clone in the previous commit.

lfs: enable the extension locally after cloning a repo with 'lfs' requirement We do the same thing on clone for the largefiles extension, as a convenience. Similar to largefiles, it's probably safer to only enable this extension on a per repo basis because it is trivial to add an lfs file. And that gives the repository some centralized VCS characteristics.

log: translate column labels at once (issue5750) This makes sure that all columns are aligned. getlogcolumns() is hosted by templatekw so the namespaces module can see it. i18n/de.po is updated so test-log.t passes with no error. "obsolete:" and "instability:" are kept untranslated.

log: remove temporary variable 'date' used only once

lock: allow to configure when the lock messages are displayed We add a new 'ui.timeout.warn' config to set a grace period before we display lock related warning: waiting for lock on PATH held by PROCESS The config is based on 'ui.timeout' and expresses a number of seconds before the warning is displayed. Negative values disable the warning altogether. The messages go to the debug output to help people trouble-shooting deadlocks.

lock: add a trylock method handling the timeout and messaging logic We are about to make the messages around lock more flexible. We move all the currently logic into a function in the lock module. We'll update the message scheme in the next changeset.

lock: use configint for 'ui.timeout' config The ui object can do the conversion itself.

scmutil: improve format pattern used in nodesummaries As spotted by Yuya Nishihara, that value is an integer.
