- add kdf_iter, cipher, rekey_kdf_iter, and rekey_cipher PRAGMAs to allow changing parameters - introduction of cipher_ctx struct to store relavent cipher details for separate read and write operations - simplified sqlite3Codec to make more understandable - simplify encryption code for first database page - simplify sqlite3_key and sqlite3_rekey, they now operate only on the main database only - documentation updates for supporting functions - reorganize tests to remove interdependencies between tests where possible - add tests for converting between different ciphers
