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

--

This is a pretty stupid fix but one which works without much risk of
regressions.  We could have used the existing TRIES but in that case
the fallback to other host would have been too limited.  With the used
value we can have several fallbacks to other hosts.  Note that the
TRIES is still cumulative and not per host.

* tools/gpgconf-comp.c (gc_component_kill): Reverse the order.

--

The order matters in a corner case; On a busy machine, there was a
race condition between gpg-agent's running KILLAGENT command and its
accepting incoming request on the socket.  If a request by
gpg-connect-agent was accepted, it resulted an error by sudden
shutdown.  This change of the order can remove such a race.

Here, we know backend=0 is none.

There was the card-timeout option in GnuPG 2.0, but it was never

sharing smartcard among multiple applications, but this didn't work
well as user's expectation (it only worked with DISCONNECT command).
This is because other parts of scdaemon assumes exclusive access.  In
GnuPG 2.1, the support of the option was removed, improving
"DISCONNECT" command always works well without this option.
