* 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.

When gpg-agent learns about a private key from its ssh-agent

because it would choke on these comments. This change lets it ignore
any additional trailing sublists.

This generic caching module is better than the ad-hoc code we used in
getkey.c. More cleanup in getkey is still required but it is a
start. There is also a small performance increase with the new cache:
With a large keyring and --list-sigs I get these numbers:
| | before | after |
|------+------------+------------|
| real | 14m1.028s | 12m16.186s |
| user | 2m18.484s | 1m36.040s |
| sys | 11m42.420s | 10m40.044s |
Note the speedup in the user time which is due to the improved cache
algorithm. This is obvious, because the old cache was just a long
linked list; the new cache are two hash tables.

* g10/import.c (import): Limit the number of considered keys to 5.

The Web Key Directory should carry only one key. However, some
providers like to put old or expired keys also into the WKD. I don't
thunk that this is a good idea but I heard claims that this is needed
for them to migrate existing key data bases.
This patch puts a limit on 5 on it (we had none right now) and also
fixes the issue that gpg could not work immediately with the requested
key because the code uses the fingerprint of the key to use the
imported key. Now the first key is used. On a second try (w/o
accessing the WKD) the regular key selection mechanism would be in
effect. I think this is the most conservative approach. Let's see
whether it helps.
