Add dshash_get_dsa_area(), able to retrieve the DSA area of a dshash table Code using GetNamedDSHash() to retrieve a dshash table may also want to limit its size, but there is actually no easy way to do so because the dsa_area of a hash table is hidden within dshash.c.
This commit adds dshash_get_dsa_area() to close the gap, which returns the dsa_area for a given dshash_table. The DSA area retrieved can then be passed to dsa_set_size_limit(), to limit its size. This accessor routine also opens the door for allocating additional objects in the same DSA area as a hash table, which may be useful for some.
