With the performance issues with regex figured out and fixed in previous
patches and regex newly gaining support for empty alternations, there is no
reason to keep re2 around anymore. It's only *marginally* faster at creating
the regex which saves at most a couple of ms, but gets beaten by regex in
every other aspect.
This removes the Rust/C/C++ bridge (hooray!), the with-re2 feature, the
conditional code that goes with it, the documentation and relevant part of the
debug/module output.

| Using the fastest ``hg status`` | |||||
| ------------------------------- | |||||
| The code for ``hg status`` needs to conform to ``.hgignore`` rules, which are | |||||
| all translated into regex. | |||||
| In the first version, for compatibility and ease of development reasons, the | |||||
| Re2 regex engine was chosen until we figured out if the ``regex`` crate had | |||||
| similar enough behavior. | |||||
| Now that that work has been done, the default behavior is to use the ``regex`` | |||||
| crate, that provides a significant performance boost compared to the standard | |||||
| Python + C path in many commands such as ``status``, ``diff`` and ``commit``, | |||||
| However, the ``Re2`` path remains slightly faster for our use cases and remains | |||||
| a better option for getting the most speed out of your Mercurial. | |||||
| If you want to use ``Re2``, you need to install ``Re2`` following Google's | |||||
| guidelines: https://github.com/google/re2/wiki/Install. | |||||
| Then, use ``HG_RUST_FEATURES=with-re2`` and | |||||
| ``HG_RE2_PATH=system|<path to your re2 install>`` when building ``hg`` to | |||||
| signal the use of Re2. Using the local path instead of the "system" RE2 links | |||||
| it statically. | |||||
| For example:: | |||||
| $ HG_RUST_FEATURES=with-re2 HG_RE2_PATH=system make PURE=--rust | |||||
| $ # OR | |||||
| $ HG_RUST_FEATURES=with-re2 HG_RE2_PATH=/path/to/re2 make PURE=--rust | |||||
