url: add cgi.escape equivalent for bytestrings This seems like a sensible enough place to put it. Differential Revision: https://phab.mercurial-scm.org/D1066

python3: move from using func_name to __name__ Previously reviewed as D964, but required some fixups and therefore seems to need a new revision. Differential Revision: https://phab.mercurial-scm.org/D1065

tests: add globs for Windows

test-conflicts: conditionalize for no-symlink platforms It seems better to create standin files for the symlinks, rather than blacklist the entire tests. Especially since link vs file doesn't seem to affect the tests. There is more instability in test-pathconflicts-{basic,merge}.t that I can't figure out.

test-extdata: conditonalize error message for Windows

test-audit-path: fill in missing output for no-symlink case It looks like this was meant to go with 989e884d1be9.

test-i18n: guard gettext test appropriately

hook: add a 'hashook' function to test for hook existence Preparing the data for some hooks can be expensive. Add a function to check if a hook exists so we can skip useless preparation if no hook is configured.
