Fix `cargo package` for the libgit-sys crate by providing a pristine
copy of the Git source tree at package time, and by building object
files and other generated files outside of this tree. While we're at it,
improve parallel builds by plumbing Cargo's make flags to the make
command invoked in our build.rs script.
We also fix a few problems that would prevent us from publishing the
libgit-sys crate: we add a license and description to Cargo.toml, and we
exclude unnecessary files from the packaged source, to stay below
crates.io's 10 MB limit.
`cargo package` for the libgit-rs crate is still broken for now, because
it will require publishing the libgit-sys crate first.
Changes from V1:
* Reworked patch #2 to build outside of the source tree rather than
running `make clean` after the build.
* Simplified patch #4 now that cleaning is no longer necessary.
* Added patch #5 to add some required Cargo.toml fields.
Josh Steadmon (5):
libgitpub: move to separate contrib/ directory
libgit-sys: add symlink to git repo root and build out of tree
libgit-sys: parallelize build with Cargo's jobserver
libgit-sys: exclude unnecessary directories in git-src
libgit-{sys,rs}: add license and description fields
