cmdutil: pass metadata from amend() to cleanupnodes `commit --amend` and amend command in core and extensions rely on cmdutil.amend() for amending a commit. So the logic to add a note to amend must reside here. This patch assumes that note will be passed in opts dictionary to the function and it will be passed to cleanupnodes and then createmarkers to store the note in the obsmarker metadata. After this patch, note can be stored on an amend changeset by passing notes as a part of opts to cmdutil.amend(). Differential Revision: https://phab.mercurial-scm.org/D1094

scmutil: add capability to cleanupnodes to take obsmarker metadata This patch adds a metadata argument to cleanupnodes() which will be dict and can be passed to obsmarker.createmarkers() and can be stored on the obsmarker. In cases when obsolescence is not enabled, the metadata argument is useless. This is a step towards storing a note in amend. Differential Revision: https://phab.mercurial-scm.org/D1093

test-hgweb-annotate-whitespace: make test compatible with chg D946 fixed a bunch of tests which had the same root cause. Please see that for details. This seems to be one of the newer tests which fails because of the same reason. Test Plan: Ran the test 'test-hgweb-annotate-whitespace.t' with and without the '--chg' option.

test-pager: make the test compatible with chg D911 tried to make this test compatible with chg but instead resulted in the test being flaky for chg. For now, disabling this test for chg because it seems difficult to fix the test. This will allow for the continuous build setup for chg. Test Plan: Ran the test 'test-pager.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1128
