[PATCH] unify passphrase-repeat logic into gpg-agent

[Daiki Ueno]

Hi,

I noticed that the function passphrase_to_dek (in g10/passphrase.c)
repeats the passphrase prompt by itself, even though for other usage
(such as key generation) gpgv2 leaves gpg-agent to do that job.  I think
that it is consistent with gpg-agent to handle any case where
passphrase-repeat is needed.

The attached patch moves the implementation of the logic from
passphrase_to_dek to gpg-agent.

This should not change the current behavior, but it will make it easier
to implement the symenc passphrase-caching which I recently proposed.
