After pushing the bitmap iterator into table-AM specific code (as part of making bitmap heap scan use the read stream API in 2b73a8cd33b7), scan_bitmap_next_block() no longer returns the current block number. Since scan_bitmap_next_block() isn't returning any relevant information to bitmap table scan code, it makes more sense to get rid of it. Now, bitmap table scan code only calls table_scan_bitmap_next_tuple(), and the heap AM implementation of scan_bitmap_next_block() is a local helper in heapam_handler.c.
