Adds the extra_components metadata, git2 as an optional dep behind the `git` feature (default-features off -> no openssl-sys/libssh2-sys), and a git_smoke bin gated on it. libgit2-sys/libz-sys run in system mode against fake pkg-config files (empty Libs) so they emit no link flags -- symbols come from the esp-idf component. Proven on device: git2 version + a blob SHA1 through the mbedTLS backend.

# libz-sys is a non-optional dependency of libgit2-sys. Left to itself it would
|
|
# either grab the host (macOS) zlib or vendor-build its own libz.a — and either
|
|
# way its zlib symbols would collide with the zlib we bundle *inside* the
|
|
# libgit2 component (deps/zlib, which lives in esp-idf's link group where the
|
|
# ordering is safe). This .pc makes libz-sys's probe succeed while emitting
|
|
# NOTHING, so it contributes no symbols and the component's bundled zlib wins.
|
|
#
|
|
# PKG_CONFIG_LIBDIR is pointed at this directory only, so neither probe can fall
|
|
# through to the host's real zlib.pc.
