sha1_name.c: teach lookup context to get_sha1_with_context()
The function takes user input string and returns the object name (binary SHA-1) with mode bits and path when the object was looked up in a tree. Additionally give hints to help disambiguation of abbreviated object names when the caller knows what it is looking for. Signed-off-by: Junio C Hamano <gitster@pobox.com>
