gpg: With --auto-key-retrieve prefer WKD over keyservers.
* g10/mainproc.c (check_sig_and_print): Print a hint on how to make
use of the preferred keyserver.  Remove keyserver lookup just by the
keyid.  Try a WKD lookup before a keyserver lookup.
--

The use of the the keyid for lookups does not make much sense anymore
since for quite some time we do have the fingerprint as part of the
signature.

gpg: Add "self-sigs-only" and "import-clean" to the keyserver options.
* g10/gpg.c (main): Change default.
--

Due to the DoS attack on the keyeservers we do not anymore default to
import key signatures.  That makes the keyserver unsuable for getting
keys for the WoT but it still allows to retriev keys - even if that
takes long to download the large keyblocks.

To revert to the old behavior add

  keyserver-optiions  no-self-sigs-only,no-import-clean

to gpg.conf.

gpg: New command --locate-external-key.
* g10/gpg.c (aLocateExtKeys): New.
(opts): Add --locate-external-keys.
(main): Implement that.
* g10/getkey.c (get_pubkey_byname): Implement GET_PUBKEY_NO_LOCAL.
(get_best_pubkey_byname): Add arg 'mode' and pass on to
get_pubkey_byname.  Change callers.
* g10/keylist.c (public_key_list): Add arg 'no_local'.
(locate_one): Ditto.  Pass on to get_best_pubkey_byname.
--

This new command is a shortcut for

  --auto-key-locate nodefault,clear,wkd,... --locate-key

and uses the default or configured AKL list but does so without local.

gpg: New import and keyserver option "self-sigs-only"
* g10/options.h (IMPORT_SELF_SIGS_ONLY): New.
* g10/import.c (parse_import_options): Add option "self-sigs-only".
(read_block): Handle that option.
--

This option is intended to help against importing keys with many bogus
key-signatures.  It has obvious drawbacks and is not a bullet-proof
solution because a self-signature can also be faked and would be
detected only later.

gpg: Fix using --decrypt along with --use-embedded-filename.
* g10/options.h (opt): Add flags.dummy_outfile.
* g10/decrypt.c (decrypt_message): Set this global flag instead of the
fucntion local flag.
* g10/plaintext.c (get_output_file): Ignore opt.output if that was
used as a dummy option aslong with --use-embedded-filename.
--

The problem here was that an explicit specified --decrypt, as
meanwhile suggested, did not work with that dangerous
--use-embedded-filename.  In contrast it worked when gpg decrypted as
a side-effect of parsing the data.

gpg: Improve the photo image viewer selection.
* g10/exec.c (w32_system): Add "!ShellExecute" special.
* g10/photoid.c (get_default_photo_command): Use the new ShellExecute
under Windows and fallbac to 'display' and 'xdg-open' in the Unix
case.
(show_photos): Flush stdout so that the output is shown before the
image pops up.
--

For Unix this basically syncs the code with what we have in gpg 1.4.
Note that xdg-open may not be used when running as root which we
support here.

For Windows we now use ShellExecute as this seems to be preferred over
"cmd /c start"; however this does not solve the actual problem we had
in the bug report.  To solve that problem we resort to a wait
parameter which defaults to 400ms.  This works on my Windows-10
virtualized test box.  If we can figure out which simple viewers are
commonly installed on Windows we should enhance this patch to test for
them.

This change allows to switch between a tofu and pgp or tofu+pgp trust

the tofu trust model is requested on the command line.  If TOFU will
ever be the default we need to tweak the model detection via TM_AUTO

* g10/gpg.c (main): remove KEYSERVER_AUTO_KEY_RETRIEVE from the
default keyserver options.
* doc/gpg.texi: document this change.
--

This is a partial reversion of
7e1fe791d188b078398bf83c9af992cb1bd2a4b3.  Werner and i discussed it
earlier today, and came to the conclusion that:

 * the risk of metadata leakage represented by a default
   --auto-key-retrieve, both in e-mail (as a "web bug") and in other
   contexts where GnuPG is used to verified signatures, is quite high.

 * the advantages of --auto-key-retrieve (in terms of signature
   verification) can sometimes be achieved in other ways, such as when
   a signed message includes a copy of its own key.

 * when those other ways are not useful, a graphical, user-facing
   application can still offer the user the opportunity to choose to
   fetch the key; or it can apply its own policy about when to set
   --auto-key-retrieve, without needing to affect the defaults.

Note that --auto-key-retrieve is specifically about signature
verification.  Decisions about how and whether to look up a key during
message encryption are governed by --auto-key-locate.  This change
does not touch the --auto-key-locate default of "local,wkd".  The user
deliberately asking gpg to encrypt to an e-mail address is a different
scenario than having an incoming e-mail trigger a potentially unique
network request.

doc: Revert the bug reporting address to bugs.gnupg.org
--

dev.gnupg org is the development platform but the canonical bug
address is and has always been bugs.gnupg.org.  We should keep on
using this address for the case that we switch the tracker again or
split it off the development system.

That is also the reason why we should keep on communicating a plain
bug number without the 'T' prefix.
