Currently the only constant for the maximum bio size is BIO_MAX_SECTORS, which is in units of 512-byte sectors, but a lot of user need a byte limit. Add a BIO_MAX_SIZE constant, redefine BIO_MAX_SECTORS in terms of it, and switch all bio-related uses of UINT_MAX for the maximum size to use the symbolic names instead.
