Heikki Linnakangas 4953a25b7f Remove HASH_DIRSIZE, always use the default algorithm to select it 
It's not very useful to specify a non-standard directory size. The
HASH_DIRSIZE option was only used for shared memory hash tables, and
those always used hash_select_dirsize() to choose the size, which in
turn just uses the default algorithm anyway. That assumption was
ingrained in hash_estimate_size(), too.
