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.

This test doesn't yet work due to the way fsmonitor is integrated with test runner
$ exit 80
test sparse interaction with other extensions
$ hg init myrepo
$ cd myrepo
$ cat > .hg/hgrc <<EOF

Test fsmonitor integration (if available)
TODO: make fully isolated integration test a'la https://github.com/facebook/watchman/blob/master/tests/integration/WatchmanInstance.py
(this one is using the systemwide watchman instance)
$ touch .watchmanconfig
$ echo "ignoredir1/" >> .hgignore
$ hg commit -Am ignoredir1
adding .hgignore
$ echo "ignoredir2/" >> .hgignore
$ hg commit -m ignoredir2
$ hg sparse --reset
$ hg sparse -I ignoredir1 -I ignoredir2 -I dir1
$ mkdir ignoredir1 ignoredir2 dir1
$ touch ignoredir1/file ignoredir2/file dir1/file
Run status twice to compensate for a condition in fsmonitor where it will check
ignored files the second time it runs, regardless of previous state (ask @sid0)
$ hg status --config extensions.fsmonitor=
? dir1/file
$ hg status --config extensions.fsmonitor=
? dir1/file
Test that fsmonitor ignore hash check updates when .hgignore changes
$ hg up -q ".^"
$ hg status --config extensions.fsmonitor=
? dir1/file
? ignoredir2/file
