dirmngr,gpg: Better diagnostic in case of bad TLS certificates.
* doc/DETAILS: Specify new status code "NOTE".
* dirmngr/ks-engine-http.c (ks_http_fetch): Print a NOTE status for a
bad TLS certificate.
* g10/call-dirmngr.c (ks_status_cb): Detect this status.
--

For example a

  gpg -v --locate-external-keys dd9jn@posteo.net

now yields

  gpg: Note: server uses an invalid certificate
  gpg: (further info: bad cert for 'posteo.net': \
                      Hostname does not match the certificate)
  gpg: error retrieving 'dd9jn@posteo.net' via WKD: Wrong name
  gpg: error reading key: Wrong name

(without -v the "further info" line is not shown).  Note that even
after years Posteo is not able to provide a valid certificate for
their .net addresses.  Anyway, this help to show the feature.

gpg: Extend --quick-gen-key for creating keys from a card.
* g10/keygen.c (parse_key_parameter_part): Add arg R_KEYGRIP and
support the special algo "card".
(parse_key_parameter_string): Add args R_KEYGRIP and R_SUBKEYGRIP.
Handle the "card" algo.  Adjust callers.
(parse_algo_usage_expire): Add arg R_KEYGRIP.
(quickgen_set_para): Add arg KEYGRIP and put it into the parameter

(quick_generate_keypair): Handle algo "card".
(generate_keypair): Also handle the keygrips as returned by
parse_key_parameter_string.
(ask_algo): Support ed25519 from a card.
--

Note that this allows to create a new OpenPGP key from an initialized
OpenPGP card or from any other supported cards.  It has been tested
with the TCOS Netkey card.  Right now a stub file for the cards might
be needed; this can be achieved by running "gpgsm --learn" with the
card plugged in.

Example:

  gpg --quick-gen-key foo@example.org card

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.

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.

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.

The problem here was that an explicit specified --decrypt, as

--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.

gpg: Print revocation reason for "rvs" records.
* g10/import.c (get_revocation_reason): New.
(list_standalone_revocation): Extend function.

Note that this function extends the "rvs" field signature-class (field
11) with the revocation reason.  GPGME does not yet parse this but it
can be expected that the comma delimiter does not break other parsers.

A new field is added to the "rvs" (and in future also the "rev")
record to carry a record specific comment.  Hopefully all parsers
meanwhile learned the lesson from other new fields and don't bail out
on more fields than they know about.

This is partial solution to

gpg: Add new usage option for drop-subkey filters.
* g10/import.c (impex_filter_getval): Add new "usage" property for
drop-subkey filter.

For example, this permits extraction of only encryption-capable
subkeys like so:

    gpg --export-filter 'drop-subkey=usage !~ e' --export $FPR
