urlutil: byteify several localized messages Flagged by pytype. Differential Revision: https://phab.mercurial-scm.org/D10872

urlutil: use the deprecation warning function on the `ui` object PyCharm flagged this as not existing, and I suspect a copy/paste error. Differential Revision: https://phab.mercurial-scm.org/D10871

dirstate-v2: Store a hash of ignore patterns (.hgignore) Later, this help extend `read_dir` caching to directories that contain ignored files (but no unknown files). Such cache must be invalidated when ignore patterns change since a formerly-ignored file might become unknown. This helps the default configuration of `hg status` where unknown files must be listed, but ignored files are not. Differential Revision: https://phab.mercurial-scm.org/D10836

rhg: propogate error coming from HgError::Abort to CommandError Differential Revision: https://phab.mercurial-scm.org/D10839

rhg: add exit code to HgError::Abort() My previous attempts to have rhg end with correct exit code was more of bug hunting. I found cases which were failing and fixed them. But as one might expect, more tests started failing. Let's add exit code `HgError::Abort()` and make it users explicitly tell what exit code they want.

rhg: split non_repo_config and `--config` loading in different functions This will help us in better handling of error caused when trying to load `--config` values. Differential Revision: https://phab.mercurial-scm.org/D10837

rhg: look for repository in ancestors also instead of cwd only Last patch introduced config reading at startup to parse value of `--repository` flag. However, that patch only tried to check for current repository at current working directory and not it's ancestors. This patch fixes that. Differential Revision: https://phab.mercurial-scm.org/D10767
