This has been tested with ADNS on Unix and with the standard
resolver. Because ADNS works it should also work on Windows.

* g10/mainproc.c (proc_encrypted): Fail for modern messages w/o MDC.
--
This change turns the missing MDC warning into an error if the message
has been encrypted using a cipher with a non-64 bit block length cipher
and it is not Twofish.
We can assume that such messages are created by code which should have
been able to create MDC packets. AES was introduced with 1.0.3 on
2000-09-18 shortly after MDC (1.0.2 on 2000-07-12). We need to
exclude Twofish because that might have been used before MDC.

* agent/pksign.c (agent_pksign_do): Use public key smartcard.
--
Since gcry_pk_verify can't handle shadowed private key, public
key SEXP should be prepared for smartcard.
* g10/dirmngr-conf.skel: New.
* g10/Makefile.am (EXTRA_DIST): Add file.
(install-data-local, uninstall-local): Install that file.
* g10/openfile.c (copy_options_file): Add arg "name", return a value,
simplify with xstrconcat, and factor warning message out to:
(try_make_homedir): here. Also install dirmngr.conf.
* g10/options.skel: Remove --keyserver entry.
--
The option --keyserver in gpg has been deprecated in favor of
--keyserver in dirmngr.conf. Thus we need to install a skeleton file
for dirmngr to set a default keyserver.

* g10/keyserver.c (keyserver_refresh): Change return type to
gpg_error_t. Use gpg_dirmngr_ks_list to print the name of the
keyserver to use.
(keyserver_search): Do not print the "no keyserver" error
message. The same error is anyway returned from dirmngr.
* g10/call-dirmngr.c (ks_status_parm_s): Add field "keyword".
(ks_status_cb): Handle other status keywords.
(gpg_dirmngr_ks_list): New.
* tools/gpgconf-comp.c (gc_options_gpg): Deprecate "keyserver".
(gc_options_dirmngr): Add "Keyserver" group and "keyserver".
--
Along with the corresponding dirmngr change this option allows to
configure the keyserver only in dirmngr.conf. Existing
configurations will continue to work. However, GUIs using gpgconf
now the keyserver option under the dirmngr (aka Key Acquirer) tab
unless they are in export mode in which the keyserver option is also
show for gpg.

This option specifies the keyserver to be used if the client does not
set another keyserver. We want to fade out the use of --keyserver in
gpg.conf in favor of specifying it here.

* tools/gpgconf-comp.c (gc_component): Change printed name.
--
All network access is handled by Dirmngr so at least in the GUI option
dialog we should acknowledge that by changing the name to an issuer to
understand term. This is an update of
819bba75aa suggested by Neal Walfield.
The former term "Network Manager" conflicts with the well known GNOME
network manager tool.

* agent/genkey.c (agent_ask_new_passphrase): Use a separate malloc for
PI2. Check return value of the malloc function.
* agent/command-ssh.c (ssh_identity_register): Use a separate malloc
for PI2. Wipe PI2.
--
For whatever stupid reasons I once allocated only one memory area and
split that into PI and PI2. This is actually a common pattern with
malloc but here we used a made up object size and do not take the
extra alignment required into account. One of these not yet hit by
a (sig)bus PC/VAX hacker bugs.
Instead of trying to fix the alignment, it is better to use a second
calloc for the second struct.

Using "check selfsig" prints only the self-signatures and indicates

Also adding Ed25519 test key.
* g10/sign.c (do_sign): Let verify signature by gpg-agent.
* agent/pksign.c (agent_pksign_do): Call gcry_pk_verify for RSA.
--
RSA signature verification should be done to prevent attacks against
RSA CRT implementations and not to return invalid signature to
adversary. Newer libgcrypt does so. For older libgcrypt and
smartcards, gpg-agent does signature verification.
* common/exechelp.h (GNUPG_SPAWN_NONBLOCK): New.
(GNUPG_SPAWN_RUN_ASFW, GNUPG_SPAWN_DETACHED): Macro to replace the
numbers.
* common/exechelp.h (gnupg_spawn_process): Change function to not take
an optional stream for stdin but to return one.
* common/exechelp-posix.c (gnupg_spawn_process): Implement change.
(create_pipe_and_estream): Add args outbound and nonblock.
* common/exechelp-w32.c (gnupg_spawn_process): Implement change.
--
In 2.1 this function is only used at one place and the stdin parameter
is not used. Thus this change is trivial for the callers but along
with estream's new es_poll it is overall simpler to use.
Note that the Windows version has not been tested.

(cmd_getinfo): Add subcommand "tor"
* tools/gpgconf-comp.c (gc_options_dirmngr): Add TOR group.

More work is required to actually make --use-tor useful. For now it
returns an error for almost all network access but as soon as we have
added the TOR feature to the http module some parts will start to
work.

* g10/call-dirmngr.c (create_context): Send option and print a verbose
error.
--
It is in general a bad idea to use honor-keyserver-url but if Dirmngr
is running in TOR mode we should not allow this option at all. We let
Dirmngr know about the use of this option and let Dirmngr tell use
whether TOR mode is active so that we can print a hint to disable that
keyserver option.
A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.
