The code that implements block sources is distributed across a couple of files. Consolidate all of it into "reftable/blocksource.c" and its accompanying header so that it is easier to locate and more self contained. While at it, rename some of the functions to have properly scoped names. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
