This change allows to link the system version of libgit2 statically.
Since `-tags static` is already used for the bundled version of the
library and to avoid breaking old workflows, `-tags
static,system_libgit2` is now used to select that.
This means that the valid combinations are:
| Flag | Effect |
|-------------------------------|-----------------------------------------------|
| _No flags_ | Dynamically-linked against the system libgit2 |
| `-tags static,system_libgit2` | Statically-linked against the system libgit2 |
| `-tags static` | Statically-linked against the bundled libgit2 |
Note that there is no way to express dynamically linking against the
bundled libgit2 because that makes very little sense, since the binaries
wouldn't be able to be distributed. If that's still desired, the
`PKG_CONFIG_PATH` environment variable can set before building the code.
[`Makefile`](https://github.com/libgit2/git2go/blob/master/Makefile) has
an example of how it is used in the CI.

This change makes the DiffNotifyCallback always use an "unowned"
*git.Diff that does _not_ run the finalizer. Since the underlying
git_diff object is still owned by libgit2, we shouldn't be calling
Diff.Free() on it, even by accident, since that would cause a whole lot
of undefined behavior.
Now instead of storing a reference to a *git.Diff in the intermediate
state while the diff operation is being done, create a brand new
*git.Diff for every callback invocation, and only create a fully-owned
*git.Diff when the diff operation is done and the ownership is
transfered to Go.

This change adds the Shutdown() method, so that the library can be
cleanly shut down. This helps significanly reduce the amount of noise in
the leak detector.
(cherry picked from commit 619a9c236b)
This change makes the underlying type of DiffFlag be uint32 instead of
int. That makes it possible to build on 32-bit systems.
Fixes: #487
(cherry picked from commit 93c4c5b30a)
This change adds support for odb.NewOdbBackendLoose(). This, together
with the git.Packbuilder, can do what Mempack does with a lot less
memory.

`repository.LookupXxx()` allocate new go `Object`s that have a reference
to a `C.git_object`. Those are then duplicated with `git_object_dup()`,
so the original `Object`s linger unnecessarily until the Go GC kicks in.
This change explicitly calls `Free()` on the originals to avoid
unnecessary accumulation of garbage.
(cherry picked from commit 2bb5930733)
This change:
* Updates the GitHub actions so that they run different commands for the
dynamic and static flavors of libgit2.
* Updates the .travis.yml file so that it does roughly the same as the
GitHub actions.
* Adds the release-* branches to the CI configurations.
