Prepare API for PBKDF that can set three costs - time (similar to iterations in PBKDF2) - memory (required memory for memory-hard function) - threads (required number of threads/CPUs). This patch also removes wrongly designed API call crypt_benchmark_kdf and replaces it with the new call crypt_benchmark_pbkdf. Two functions for PBKDF per context setting are introduced: crypt_set_pbkdf_type and crypt_get_pbkdf_type. The patch should be backward compatible when using crypt_set_iteration_time function (works only for PBKDF2). Signed-off-by: Milan Broz <gmazyland@gmail.com>
