amend: add boolean to ignore date-only change I want to add -D/--currentdate option, which should behave slightly different from the update-timestamp option.

amend: refactor commit date handling There's no need to parse a date tuple. Just do it for user option.

test-amend: remove uninteresting fields from log output to deduplicate tests We aren't testing the behavior of obsolescence-based amend.

pull: use opts.get('bookmark') instead of opts['bookmark'] This is done because at places in hgsubversion, we call the function directly. I expect there might be more instances in extensions out there which calls commands.push() directly. So let's not require explicitly passing of bookmark value. The use of opts['bookmark'] was introduced in bad05a6afdc89cc58a2af320698ab29bd8de62d4. Differential Revision: https://phab.mercurial-scm.org/D5484

amend: add config option to update time to current in hg amend (issue5828) The given config option i.e. `rewrite.update-timestamp` updates date to current when //True//. However when only date is to be updated to current with the working directory clean and no other attributes changing then it does not amend as stated in issue 5828. Further when `--date` flag is specified along with the new config option then `--date` is given priority over the config option. Differential Revision: https://phab.mercurial-scm.org/D5491

tests: correct version check in clientreactor test Experimentally, `(3, 6, 3)` is less than `sys.version_info` on an actual Python 3.6.3 installation. Let's just check `< (3, 6, 4)` instead of `<= (3, 6, 3)` so we stop seeing this bogus failure. Differential Revision: https://phab.mercurial-scm.org/D5502
