apply: split load_preimage() helper function out
Given a patch for a single path, the function apply_data() reads the preimage in core, and applies the change represented in the patch. Separate out the first part that reads the preimage into a separate helper function load_preimage(). Signed-off-by: Junio C Hamano <gitster@pobox.com>
