@brief Initialize the hash
@details
Initialize the hash, by defining and giving valid values for
its elements. The failure to allocate memory for the
hash->array element will not result in a fatal failure. The
dynamic array that is part of the hash will allocate memory
as required during insertion.
@param[in,out] hash The hash that is initialized
@param[in] charset The charater set information
@param[in] size The hash size
@param[in] key_offest The key offset for the hash
@param[in] key_length The length of the key used in
the hash
@param[in] get_key get the key for the hash
@param[in] free_element pointer to the function that
does cleanup
@return inidicates success or failure of initialization
@retval 0 success
@retval 1 failure
