Move from ssl_*2.c to ssl_test_lib.c: * Functions that have exactly identical definitions in the two programs, and that don't reference the global variable opt which has a different type in the client and in the server. Also declare these functions in ssl_test_lib.h. Move from ssl_*2.c to ssl_test_common_source.c: * Functions that have exactly identical definitions in the two programs, but access fields of the global variable opt which has a different structure type in the client and in the server. * The array ssl_sig_hashes_for_test, because its type is incomplete.
