gpg: Replace --override-compliance-check by a real fix.
* common/compliance.c (gnupg_pk_is_allowed): Handle EdDSA.
* g10/gpg.c (oOverrideComplianceCheck): Remove.
(opts): Turn --override-compliance-check into a dummy option.
* g10/options.h (opt): Remove override_compliance_check.
* g10/sig-check.c (check_key_verify_compliance): Remove use of that
option.
--

The introduction of --override-compliance-check actually hid the real
cause for the signature verification problem in de-vs mode for the
Ed25519 key.  The real fix is to handle the EdDSA algorithm in
gnupg_pk_is_allowed.

Note that this patch also introduces a compression check for signing
which was never done in the past.

--

This extends the long available OCB and EAX decryption feature.  Due
to the meanwhile expired patent on OCB there is no more reason for
using EAX.  Thus we forcefully use OCB if the AEAD feature flag is set
on a key.

In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.

--

With the global options we can now avoid that a user changes the
Root-CA trust by editing the trustlist.txt.  However, to implement
this we need a new option so that we don't need to rely on some magic
like --no-allow-mark-trusted has been put into a force section.

The second option makes system administration easier as it allows to
keep the trustlist in a non-distributed file.

In case a system-wide config exists but no local file, the component

update this file.  This fixes this by detecting the presense of a
system-wide config file.

This applies only to 2.2; the configuration system in 2.3 has been
heavily changed to better handle system-wide configuration files.

There is one important use case for this: For systems configured
globally to use de-vs mode, Ed25519 and other key types are not
allowed because they are not listred in the BSI algorithm catalog.
Now, our release signing keys happen to be Ed25519 and thus we need to
offer a way for users to check new versions even if the system is in
de-vs mode.  This does on purpose not work in --batch mode so that
scripted solutions won't accidently pass a signature check.

A generated passphrase has enough entropy so that all kind of extra
checks would only reduce the actual available entropy.  We thus detect
if a passphrase has been generated (and not changed) and skip all
passphrase constraints checking.

This fixes a bug with user ids with leading spaces because:

wks-client lists all mail addresses from the key and matches them to the
requested mail address.

If there are several user-ids all with the same mail address
wks-client picks one of them and then extracts exactly that user id.
However, here it does not match by the mail address but by the full
user-id so that we can be sure that there will be only one user-id in
the final key.

The filter built expression unfortunately strips leading blanks but
requires a verbatim match.  Thus it won't find the user id again and
errors out.

The new -t flag and a non-trimming strtokenize solves the problem.

Requirements for a passphrase to protect a private key and for a
passphrase used for symmetric encryption are different.  Thus a
the use of a different pattern file will be useful.  Note that a
pattern file can be used to replace the other passphrase constraints
options and thus we don't need to duplicate them for symmetric
encryption.

Here is a simple pattern file:

====================
# Pattern to reject passwords which do not comply to
#   - at least 1 uppercase letter
#   - at least 1 lowercase letter
#   - at least one number
#   - at least one special character
# and a few extra things to show the reject mode

# Reject is the default mode, ignore case is the default
#[reject]
#[icase]

# If the password starts with "foo" (case insensitive) it is rejected.
/foo.*/

[case]

# If the password starts with "bar" (case sensitive) it is rejected.
/bar.*/

# Switch to accept mode: Only if all patterns up to the next "accept"
# or "reject" tag or EOF match, the password is accepted.  Otherwise
# the password is rejected.

[accept]

/[a-z]+/

Due to the unfortunate shutdown of the keyserver pool, the long term
defaults won't work anymore.  Thus it is better to change them.

For https access keyserver.ubuntu.com is now used because it can be
expected that this server can stand the load from newer gnupg LTS
versions.

For http based access the Dutch Surfnet keyserver is used.  However
due to a non-standard TLS certificate this server can not easily be
made the default for https.

Note: that the default server will be changed again as soon as a new
connected keyserver infrastructure has been established.
