Library_State had two functions that did the same thing,
algo_factory and algorithm_factory. This is confusing so for consistency/simplicity, remove algo_factory, making algorithm_factory the function to call. In 1.7.14, several functions in lookup.h, including retrieve_block_cipher, retrieve_hash, etc were changed to accept a Library_State& reference. However it turns out with the modified design I've settled upon for 1.8 that it is not necessary to change those interfaces; instead they always refer to the global_state algorithm factory which is exactly the semantics one would expect/desire 99% of the time (and is source compatible with code written for 1.6, also a plus)
