git-svn: set the OID length based on hash algorithm
When reading the configuration or when creating a new repository, load the extensions.objectFormat value and set the object ID length to 64 if it's "sha256". Note that we use the hex length in git-svn because most of our processing is done on hex values, not binary ones.
