Update to libgit2 d675982a153

There's been some changes to the checkout strategy, especially the
SAFE_CREATE mode, which is now the RECREATE_MISSING flag, though that
shouldn't be necessary to use in the general case.

The largest changes come from the removal of the signture from
ref-modifying functions/methods and the removal of the reflog string in
all but those directly related to moving references.
