Such code should actually go into libksba and we will eventually do
that.  However, for now it is easier to keep it here.

Update copyright notices.
--

Note that for this LTS version we now print g10 Code as the first
copyright holder with --version.  This is to avoid confusion at our
customers, now that we also provide a Linux^WGNU/Linux version of
GnuPG VS-Desktop and the Windows version has always shown g10 Code.

common: Fix creation of Windows socket directories.
* common/homedir.c (w32_try_mkdir): Remove.
(standard_homedir): Use gnupg_mkdir instead of w32_try_mkdir.
(_gnupg_socketdir_internal): Ditto.
--

The w32_try_mkdir was once introduced for WindowsCE and unfortunately
at a too brief inspection it looks like it does the utf8->wchar
conversion.  Which it does not.  Thus I obviously never tested the
switch to from APPDATA to LOCAL_APPDATA with a non-ascii account name.
That might have been due to the use of the very same code for the
homedir - but there is other code in gpg to create the homedir; thus a
failure here is mostly fixed later.

The missing error diagnostic was - and is - on purpose to avoid such
error messages due to a race between several running gpg instances.

missed to add the HKCU etc al string.

# gpgconf.ctl
#
# This file is used to change the directories where the gpg components
# are installed.  It does not change the configuration directories.
# The file is expected in the same directory as gpgconf.  The physical

# and lines starting with pound signed are ignored.  No errors are
# printed for unknown keywords or commands.  The only defined key for
# now is "rootdir" which must be followed by one optional space, an
# equal sign, and the value for the root directory.  Environment
# variables are substituted in standard shell manner, the final value
# must start with a slash, trailing slashed are stripped.

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.

--

That is actually a more correct directory than APPDATA.  This fixes
a problem with installations where the APPDATA is non a network drive
and the resulting socket filename is truncated in our socket helper
function (because we use sockaddr also for our local socket
emulation on Windows).

LOCAL_APPDATA is expected to be on the local box and thus in the
majority of cases the resulting socket file name will be short enough.

--

To test this switch the Windows Console to "legacy mode"

Windows versions (and the legacy console) don't have a proper font
installed for this.  Without this patch this runs into a log_fatal
error.

The mitigation we implement is to fallback to WriteConsoleA, that is
accepting wrong encoding and to print a note about the problem.

With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these

The rules for the command line parser are not cleary specified - if at
all.  See the comment in t-w32-cmdline.c.

We can't use the mingw version because that would require to change
all argv handling to be wchar_t and that only for Windows.  That would
be too ugly.  Parsing the command line into argv by us is much easier
and we can do that only if needed - i.e. if globing is required (we
are prepared for this) or a non-ASCII character has been encountered.
This way we keep things stable and only fix the currently not working
Unicode problem.

sm: Support AES-GCM decryption.
* sm/gpgsm.c (main): Use gpgrt_fcancel on decryption error if gpgrt
supports this.
* sm/decrypt.c (decrypt_gcm_filter): New.
(gpgsm_decrypt): Use this filter if requested.  Check authtag.
* common/compliance.c (gnupg_cipher_is_allowed): Allow GCM for gpgsm
in consumer (decrypt) de-vs mode.

We allow GCM in de-vs mode for decryption although this has not been
evaluation.  It is decryption and thus no serious harm may happen.

gpg,sm: Simplify keyserver spec parsing.
* common/keyserver.h: Remove.
* sm/gpgsm.h (struct keyserver_spec): Remove.
(opt): Change keyserver to a strlist_t.
* sm/gpgsm.c (keyserver_list_free): Remove.
(parse_keyserver_line): Remove.
(main): Store keyserver in an strlist.
* sm/call-dirmngr.c (prepare_dirmngr): Adjust for the strlist.  Avoid
an ambiguity in dirmngr by adding a prefix if needed.

* g10/options.h (struct keyserver_spec): Move definition from
keyserver.h to here.  Remove most fields.
* g10/keyserver.c (free_keyserver_spec): Adjust.
(cmp_keyserver_spec): Adjust.
(parse_keyserver_uri): Simplify.
(keyidlist): Remove fakev3 arg which does not make any sense because
we don't even support v3 keys.

We now rely on the dirmngr to parse the keyserver specs.  Thus a bad
specification will not be caught immediately.  However, even before
that dirmngr had stricter tests.

Note that this is not finished because we need to implement a password
callback.  For now "abc" is used as passwort.

Latest libksba is also required to return the required info.

Note that this change also prints the used algorithm and shows some
existsing diagnostics only in verbose mode.
