cache.h: hide on-disk index details
The on-disk format of the index file is a detail whose implementation is neatly encapsulated in read-cache.c; there is no need to expose it to the general public that include the cache.h header file. Also add a prominent mark to read-cache.c to delineate the parts that deal with the index file I/O routines from the remainder of the file. Signed-off-by: Junio C Hamano <gitster@pobox.com>
