Subject: [PATCH] merge: Expose recursion limit merge option (#642) (#644)

The `recursion_limit` merge option provided by libgit2 is currently not
exposed and thus inaccessible to Git2Go users. Let's expose it to let
users control creation of recursive merge bases.

(cherry picked from commit 7e726fda6ec2b5d773e5a8b54ed06378a53c0f7f)
