Add hash_free_all() to factor common code of iterating over all members of a hash to free them with a single nasm_free(). Split strtbl_find() into strtbl_find() and strtbl_add(). It is very unlikely that the same call site will want to have both of these functionalities, and in the end the code for the two functions are surprisingly different. Signed-off-by: H.
