teach convert_to_git a "dry run" mode
Some callers may want to know whether convert_to_git will actually do anything before performing the conversion itself (e.g., to decide whether to stream or handle blobs in-core). This patch lets callers specify the dry run mode by passing a NULL destination buffer. The return value, instead of indicating whether conversion happened, will indicate whether conversion would occur. For readability, we also include a wrapper function which makes it more obvious we are not actually performing the conversion.
