memblock: Track total size of regions automatically
Total size of memory regions was calculated by memblock_analyze() requiring explicitly calling the function between operations which can change memory regions and possible users of total size, which is cumbersome and fragile. This patch makes each memblock_type track total size automatically with minor modifications to memblock manipulation functions and remove requirements on calling memblock_analyze(). [__]memblock_dump_all() now also dumps the total size of reserved regions.
