This reflects upstream libgit2's GIT_EXPERIMENTAL_SHA256. This is an ABI-breaking change. Future releases with this feature may introduce breakages without notice Use at your own risk. Library authors: DO NOT enable this feature by default in your dependencies. Due to Cargo's additive features, downstream users cannot deactivate it once enabled.

What this is for
Integrate upstream libgit2 experimental SHA256 support in
libgit2-sys, includingunstable-sha256, gating all new ABI/API changes. We don't offer any SemVer or stability for this feature, as it is subject to change in upstream.libgit2-syssystem lib probing also support discoveringlibgit2-experimental.soat best effort. Since-experimentallib is ABI-incompatible with a normal build, if you enableunstable-sha256, it won't probe ordinarylibgit2.so.systestto check SHA256 bindings.Note: there is no git2-rs high level API support in this PR
