[PATCH] Allow the user to specify AES256 as well as AES128.

[NIIBE Yutaka]

Hello, 

I think that the feature for stronger encryption scheme for key store
will be nice.

Although it is a story in future for me, I could imagine that some
people using RSA 4096-bit key now (w/ enough entropy for their pass
phrases) would like that, to match its content.

Well, I have a suggestion that it will be better to use SHA-2 of
relevant size, instead of SHA-1.  It will be more coherent, then.

I'm not sure if it should be a user option or not.  It makes more
sense for me, when GnuPG selects appropriate key store scheme
automatically.

Please have a look at doc/HACKING for commit log requirement.
Perhaps, you'd like to submit doc/DCO.
