gpg: Make symmetric + pubkey encryption de-vs compliant.

* g10/mainproc.c (proc_encrypted): Make symmetric + pubkey encryption
de-vs compliant.

* g10/mainproc.c (struct symlist_item): New.
(struct mainproc_context): Add field symenc_list.
(release_list): Free that list.
(proc_symkey_enc): Record infos from symmetric session packet.
(proc_encrypted): Check symkey packet algos

The original check was too strong because it is in fact compliant to
encrypt with a symmetric key and and public key.  Thus decryption
should issue a compliance status.

In addition we now check that the cipher algorithms used to
symmetrically encrypt the session key are all compliant.  This is
similar to our check for all public key encrypted session key packets.
