Administrator requested to merge cc/libgit2 into main Sep 09, 2021

Created by: camdencheek

This PR implements a MVP-version of commit and diff search using libgit2 rather than git CLI.

Everything in this PR is protected behind the cc_libgit2 feature flag, so merging this should make no changes to actively-running code on main. In the spirit of incremental changes, this implementation is not feature complete, and the missing parts are detailed below. However, I wanted to get this to a state that it could be reasonably run end-to-end for experimenting with new features and performance enhancements.
