Fix some context, data, and key memory leaks in gpgme.
The context and data cleanup just involved adding missing
gpgme_release() and gpgme_data_release() calls in a few places.
The key usage was a little more involved:
* Fix crypt_free_key(). It wasn't freeing the key passed in, and
didn't work properly if multiple keys were passed in. It also was
missing a call to gpgme_key_unref().
* Add free_recipient_set() to properly unref all the keys before
freeing the array.
* Fix get_candidates() to ref keys added to the crypt_key_t list, and
unref the keys returned by gpgme_op_keylist_next().
* Change usages of gpgme_key_release() to gpgme_key_unref(). The former
was deprecated in gpgme version 0.4.1 (2003-06-06).
