Daniel Kahn Gillmor be99eec2b1 gpg: drop import-clean from default keyserver import options
* g10/gpg.c (main): drop IMPORT_CLEAN from the
default opt.keyserver_options.import_options
* doc/gpg.texi: reflect this change in the documentation

Given that SELF_SIGS_ONLY is already set, it's not clear what
additional benefit IMPORT_CLEAN provides.  Furthermore, IMPORT_CLEAN
means that receiving an OpenPGP certificate from a keyserver will
potentially delete data that is otherwise held in the local keyring,
which is surprising to users who expect retrieval from the keyservers
to be purely additive.

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 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.

--

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.
