hashtable_init description doesn't match function.

[StrikerMan780]

The function declaration is

void hashtable_init( hashtable_t* table, int key_size, int item_size, int initial_capacity, void* memctx );

but the description says:

hashtable_init
--------------

    void hashtable_init( hashtable_t* table, int item_size, int initial_capacity, void* memctx )

Initialize a hashtable instance. `item_size` specifies the size, in bytes, of the data type holding a single item stored
in the table. `initial_capacity` is the number of items to allocate storage for initially - capacity will automatically
grow as needed, by reallocating memory.

So, I'm unsure what to do here.

In fact, most of them don't match the description or example.
