* g10/encrypt.c (setup_symkey): Use default_cipher_algo function

(encrypt_simple): Use setup_symkey.
--
Aside of removing code duplication this patch fixes the flaw that the
S2K cipher algorithm was used when mixing public key and symmetric
encryption or signatures with symmetric encrypion. The
default_algorithm function should be used here so that the command
line option --cipher-algo and --personal-cipher-preferences have an
effect.

This patch allows to decrypt data encrypted using the new AEAD
mechanism as specified in rfc4880bis. Although preferences are used
to enable this new mode, it is useful to have at least a decryption
option in case a user switches between GnuPG 2.2 and newer versions.
The new AEAD mechanism is much faster than the current CFB+MDC and
thus 2.2 will allow faster decryption of symmetric only decryption.
This patch is based on the current master (2.3) code base and includes
a few other patches. In particular

Yes, I know that there is a lot of code duplication. In fact some of

guarantee that returned memory buffers via gcry_sexp_extract_param are

directly extract into an unsigned int or char *.
