tests: use interfaceutil in simplestorerepo Without it, we crash at module import time. This has likely been busted since 856f381ad74b. Differential Revision: https://phab.mercurial-scm.org/D3884

rebase: improve output of --dry-run Improved output when in dryrun, for user to make sure that no change will be written to repository. Differential Revision: https://phab.mercurial-scm.org/D3764

status: add support for log-like template keywords and functions It's bound to ctx2 since "hg status" can be considered to show the status of the files at ctx2 given ctx1 as the base.

resolve: add support for log-like template keywords and functions It uses wctx as the associated revision since "hg resolve" is the command to manipulate the working directory files.

manifest: add support for log-like template keywords and functions "hg manifest --all" isn't supported since it has no single associated revision.

files: add support for log-like template keywords and functions Note that the ctx does not point to the revision where the file was last changed, but the revision specified by -rREV option.
