Nathan Bossart 18452b70ac Accommodate very large dshash tables. 
If a dshash table grows very large (e.g., the dshash table for
cumulative statistics when there are millions of tables), resizing
it may fail with an error like:

	ERROR: invalid DSA memory alloc request size 1073741824

To fix, permit dshash resizing to allocate more than 1 GB by
providing the DSA_ALLOC_HUGE flag.
