resourceutil: don't limit resources to the `mercurial` package This should make things a little clearer, in that it now requires the full package name to access a resource. But the real motivation is that `extensions._disabledpaths()` walks the `hgext` directory looking for bundled extensions. This in turn feeds, among other things: 1) Listing disabled extensions in `hg help extensions` 2) Indicating that an unknown command is in a non-enabled extension 3) Displaying help for non-enabled extensions 4) Generating documentation 5) Announcing LFS is auto-enabled (or not) when cloning from an LFS source The filesystem based ResourceReader will happily return *.py and *.pyc, but the one supplied by PyOxidizer doesn't. Presumably we can change that. The only other idea I had here is for setup.py to generate a text file containing the list of extensions, but that doesn't seem great when running from source.

setup: include `defaultrc` in the package list This is needed to access the config files via the resourceutil framework, which is needed to embed the config files when uing PyOxidizer. Differential Revision: https://phab.mercurial-scm.org/D7771

tests: update test-releasenotes-formatting.t output The output seems to be left outdated because running this test requires fuzzy-wuzzy which is not generally installed. Differential Revision: https://phab.mercurial-scm.org/D7723

tests: fix a copy/paste name duplication in storage.py Flagged by PyCharm as a redeclared name without usage, because the name matches the function immediately preceding it. But since this differs by doing regular reads instead of raw reads, I assume we still want it. But I don't see either function being called anywhere.

commit: change default `editor` parameter to None Flagged by PyCharm as a boolean not being callable later where it is used. There's no actual bug here because of `if editor` checks before using. Differential Revision: https://phab.mercurial-scm.org/D7768

cleanup: drop redundant character escapes outside of `[]` Flagged by PyCharm. `@`, `:`, `<`, `>`, and `{` aren't special characters. (I'm a bit surprised that it doesn't also want to unescape `}` in schemes.py.) Differential Revision: https://phab.mercurial-scm.org/D7767

cleanup: drop redundant character escapes from `[]` character sets Flagged by PyCharm. Most special characters lose their special meaning inside square brackets. The `-` in util.py doesn't need to be escaped because it is the last character in the set. Differential Revision: https://phab.mercurial-scm.org/D7766

cleanup: replace contiguous spaces in regex patterns with an explicit count Flagged by PyCharm, this form should be more readable. Differential Revision: https://phab.mercurial-scm.org/D7765

mq: avoid using `__file__` to compare modules This fixes ~70 tests when using an oxidized executable, bringing the current failure count down to 92 (with 110 skips) when templates/ is copied next to the executable. Differential Revision: https://phab.mercurial-scm.org/D7778

util: avoid referencing `time.clock()` on Windows when missing (issue6238) It's been removed in 3.8, and issues a deprecation warning since 3.3. Differential Revision: https://phab.mercurial-scm.org/D7780
