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.

* common/compliance.c (gnupg_pk_is_compliant): Remove the Elgamal
signing check. We don't support Elgamal signing at all.
(gnupg_pk_is_allowed) <de-vs>: Revert encryption/decryption for RSA.
Check the curvenames for ECDH.
* g10/pubkey-enc.c (get_session_key): Print only a warning if the key
is not compliant.
* sm/decrypt.c (gpgsm_decrypt): Ditto. Use the same string as in gpg
so that we have only one translation.
--
We always allow decryption and print only a note if the key was not
complaint at the encryption site.

* 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.

The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
