* 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.

Gbp-Pq: Name gpg-drop-import-clean-from-default-keyserver-import-optio.patch
As of 2.2.17, GnuPG will refuse to accept any third-party
certifications from OpenPGP certificates pulled from the keyserver
network.
The SKS keyserver network currently has at least a dozen popular
certificates which are flooded with enough unusable third-party
certifications that they cannot be retrieved in any reasonable amount
of time.
The hkps://keys.openpgp.org keyserver installation offers HKPS,
performs cryptographic validation, and by policy does not distribute
third-party certifications anyway.
It is not distributed or federated yet, unfortunately, but it is
functional, which is more than can be said for the dying SKS pool.
And given that GnuPG is going to reject all the third-party
certifications anyway, there is no clear "web of trust" rationale for
relying on the SKS pool.
One sticking point is that keys.openpgp.org does not distribute user
IDs unless the user has proven control of the associated e-mail
address. This means that on standard upstream GnuPG, retrieving
revocations or subkey updates of those certificates will fail, because
upstream GnuPG ignores any incoming certificate without a user ID,
even if it knows a user ID in the local copy of the certificate (see
https://dev.gnupg.org/T4393).
However, we have three patches in
debian/patches/import-merge-without-userid/ that together fix that
bug.

* 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.

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.
