block: move qmp and info dump related code to block/qapi.c
This patch is a pure code move patch, except following modification: 1 get_human_readable_size() is changed to static function. 2 dump_human_image_info() is renamed to bdrv_image_info_dump(). 3 in qmp_query_block() and qmp_query_blockstats, use bdrv_next(bs) instead of direct traverse of global array 'bdrv_states'. 4 collect_snapshots() and collect_image_info() are renamed, unused parameter *fmt in collect_image_info() is removed. 5 code style fix. To avoid conflict and tip better, macro in header file is BLOCK_QAPI_H instead of QAPI_H. Now block.h and snapshot.h are at the same level in include path, block_int.h and qapi.h will both include them.
