* main.h, misc.c (default_cipher_algo, default_compress_algo): New.

Browse Source 
Return the default algorithm by trying --cipher-algo/--compress-algo, then
the first item in the pref list, then s2k-cipher-algo or ZIP.

* sign.c (sign_file, sign_symencrypt_file), encode.c (encode_simple,
encode_crypt): Call default_cipher_algo and default_compress_algo to get
algorithms.

* g10.c (main): Allow pref selection for compress algo with --openpgp.

default_compress_algo to get algorithms.
* g10.c (main): Allow pref selection for compress algo with
--openpgp.
* mainproc.c (proc_encrypted): Use --s2k-digest-algo for
passphrase mangling rather than --digest-algo.
