gpg,sm: Error out on compliance mismatch while decrypting.
* g10/pubkey-enc.c (get_session_key): Bail out if the algo is not
allowed in the current compliance mode.
* sm/decrypt.c (gpgsm_decrypt): Ditto.
--

The idea here is that the owner of the key created a non-compliant key
and later receives a mail encrypted to that key.  The sender should
have checked this key too but we can't guarantee that.  By hard
failing here the owner of the key will notice that he had created a
non-compliant key and thus has a chance to generate a new compliant
key.  In case the compliant criteria changes and the owner wants to
decrypt an old message he can still switch gpg to another compliant
mode.

This is a straightforward change to handle new user ids.

How to test:

With an empty keyring run

  gpg --with-key-origin --locate-key \
      --auto-key-locate clear,nodefault,wkd  wk@gnupg.org

and then append a new keyid using

  gpg --with-key-origin --locate-key \
      --auto-key-locate clear,nodefault,wkd  wk@g10code.com

Works with my current key 80615870F5BAD690333686D0F2AD85AC1E42B367.

Previously, when generating a subkey, gpg would ask for the passphrase
of the primary key.  If that dialog is canceled, gpg would ask a
second time for a passphrase to protect the new subkey.

Fix this by handling the error.

gpg,gpgsm: Fix compliance check for DSA and avoid an assert.
* common/compliance.c (gnupg_pk_is_compliant): Swap P and Q for DSA
check.  Explicitly check for allowed ECC algos.
(gnupg_pk_is_allowed): Swap P and Q for DSA check.
* g10/mainproc.c (proc_encrypted): Simplify SYMKEYS check.  Replace
assert by debug message.

Note that in mainproc.c SYMKEYS is unsigned and thus a greater than 0
condition is surprising because it leads to the assumption SYMKEYS
could be negative.  Better use a boolean test.

The assert could have lead to a regression for no good reason.  Not
being compliant is better than breaking existing users.

indent: Always use "_(" and not "_ (" to mark translatable strings.

This makes greping much easier and we have done that since ever.
