dirmngr: Change the default keyserver.
* configure.ac (DIRMNGR_DEFAULT_KEYSERVER): Change to
keyserver.ubuntu.com.

* dirmngr/certcache.c (cert_cache_init): Disable default pool cert.
* dirmngr/http-ntbtls.c (gnupg_http_tls_verify_cb): Ditto.
* dirmngr/http.c (http_session_new): Ditto.

* dirmngr/server.c (make_keyserver_item): Use a different mapping for
the gnupg.net names.
--

Due to the unfortunate shutdown of the keyserver pool, the long term
defaults won't work anymore.  Thus it is better to change them.

For https access keyserver.ubuntu.com is now used because it can be
expected that this server can stand the load from newer gnupg LTS
versions.

For http based access the Dutch Surfnet keyserver is used.  However
due to a non-standard TLS certificate this server can not easily be
made the default for https.

Note: that the default server will be changed again as soon as a new
connected keyserver infrastructure has been established.

wkd: Fix client issue with leading or trailing spaces in user-ids.

* common/t-stringhelp.c (test_strtokenize_nt): New test cases.

* tools/wks-util.c (wks_list_key): Use strtokenize_nt and the recsel
flag -t.
--

This fixes a bug with user ids with leading spaces because:

wks-client lists all mail addresses from the key and matches them to the
requested mail address.

If there are several user-ids all with the same mail address
wks-client picks one of them and then extracts exactly that user id.
However, here it does not match by the mail address but by the full
user-id so that we can be sure that there will be only one user-id in
the final key.

The filter built expression unfortunately strips leading blanks but
requires a verbatim match.  Thus it won't find the user id again and
errors out.

The new -t flag and a non-trimming strtokenize solves the problem.

A generated passphrase has enough entropy so that all kind of extra

if a passphrase has been generated (and not changed) and skip all
passphrase constraints checking.

Requirements for a passphrase to protect a private key and for a
passphrase used for symmetric encryption are different.  Thus a
the use of a different pattern file will be useful.  Note that a
pattern file can be used to replace the other passphrase constraints
options and thus we don't need to duplicate them for symmetric
encryption.

It would be too confusing if gpg and gpgsm use different key storages.
Further, other components (e.g. dirmngr or gpg-wks-client) which call
gpg or gpgsm need to be aware that the keyboxd is used and pass that
option on the command line.  Now that common.conf is always read (even

It appears that SP-800-73-x is not too clear about the format of these

have only the PIX in DO 0x4F and only the RID in object 0x79/0x4F.

However, other cards as well as the PivApplet Javacard applet have the
full AID in 0x4F (which actually seems closer to what the standard
says). PivApplet also has the full AID in 0x79/0x4F, but this is
probably incorrect. (Here is a long discussion of the matter from an
OpenSC author:

This features allows to mark keys to be used for OpenPGP.  This is
done by putting additional extended key infos into the certificate
stored on the cards.  Only if any such extended key usage is detected
for a stored certificate this new mode chimes in.

This feature gives the card issuer a high flexibility on how to make
sure certain keys are used with OpenPGP.

w32: Always use Unicode for console input and output.
* common/init.c (_init_common_subsystems) [W32]: Set the codepage to
UTF-8 for input and putput.  Switch gettext to UTF-8.
* tools/gpgconf.c (main): Display the input and output codepage if
they differ.
* g10/gpg.c (utf8_strings) [W32]: Make sure this is always set.

With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly.  However, this seems to work only
with recent versions of Windows-10.
