This patch adds support for a to be proposed OpenPGP ferature:

  Introduce the Key Block subpacket to align OpenPGP with CMS.

  This new subpacket may be used similar to the CertificateSet of
  CMS (RFC-5652) and thus allows to start encrypted communication
  after having received a signed message.  In practice a stripped down
  version of the key should be including having only the key material
  and the self-signatures which are really useful and shall be used by
  the recipient to reply encrypted.

  #### Key Block

  (1 octet with value 0, N octets of key data)

  This subpacket MAY be used to convey key data along with a signature
  of class 0x00, 0x01, or 0x02.  It MUST contain the key used to create
  the signature; either as the primary key or as a subkey.  The key
  SHOULD contain a primary or subkey capable of encryption and the
  entire key must be a valid OpenPGP key including at least one User ID
  packet and the corresponding self-signatures.

  Implementations MUST ignore this subpacket if the first octet does not
  have a value of zero or if the key data does not represent a valid
  transferable public key.

Handle the "card" algo.  Adjust callers.

--

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

The use of the the keyid for lookups does not make much sense anymore

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.

This option is intended to help against importing keys with many bogus

solution because a self-signature can also be faked and would be

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.

under Windows and fallbac to 'display' and 'xdg-open' in the Unix

(show_photos): Flush stdout so that the output is shown before the

--

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.
