Details:
Attached patch adds functions:
struct hash_table *hash_copy(const struct hash_table *h);
bool hash_equal(const struct hash_table *a,
const struct hash_table *b);
for copying and testing equality of hash tables.
The copy is a copy in the deep sense (i.e. new
buckets are created), but element key and value
pointers are just copied by value (i.e. elements
are only shallow copied).
Equality is satisfied if the pointer is the
same, or both are not NULL, have the same fcmp
fval, and free functions, have the same number
of elements, and all element key/value pointers
are equal in the order traversed by the hash
iterator.
