 Account for the -1 hack to fit 0x10000 in a short in hash_page.c
 Introduce a HASH_BSIZE macro to return the blocksize; in the 64K case this
 returns 0xffff to avoid overflow. This is used where sizes are stored.
 If MAX_BSIZE == hashp->BSIZE (65536) then it does not fit in a short, and
 we end up storing 0... This means that every entry needs a page. We store
 MAX_BSIZE - 1 here, but it would be better to always store (avail - 1) here
 so that we don't waste a byte and be consistent.
