rust-regex: fix shortcut for exact matches The current shortcut for rootglobs that can be simplified to exact matches does not work, it instead treats the pattern as a regex, which is not the same thing. This changes fixes the behavior and introduces a test for this behavior. Differential Revision: https://phab.mercurial-scm.org/D6489

rust-filepatterns: use bytes instead of String In my initial patch, I introduced an unnecessary hard constraint on UTF-8 filenames and patterns which I forgot to remove. Although the performance penalty for using String might be negligible, we don't want to break compatibility with non-UTF-8 encodings for no reason. Moreover, this change allows for a cleaner Rust core API. This patch introduces a new utils module that is used with this fix. Finally, PatternError was not put inside the Python module generated by Rust, which would have raised a NameError. Differential Revision: https://phab.mercurial-scm.org/D6485

phabricator: make `hg debugcallconduit` work outside a hg repo I am trying to write some automations around phabricator and having debugcallconduit work outside a hg repo will be nice! Marking command as optionalrepo instead of norepo because we might to load repo/.hg/hgrc. Differential Revision: https://phab.mercurial-scm.org/D6499

phabricator: pass ui instead of repo to callconduit This will help us make `hg debugcallconduit` work outside a hg repo as next patch will mark that command as no repo. Differential Revision: https://phab.mercurial-scm.org/D6498

phabricator: pass ui into readurltoken instead of passing repo The goal of this series is to make `hg debugcallconduit` work outside of a hg repo. This patch, removes requirement of repo object from readurltoken as we only need ui there. It also updates the callers to pass in ui instead of repo.
