dirmngr: Remove all system daemon features.
* dirmngr/dirmngr.h (opts): Remove fields 'system_service' and

* common/asshelp.c (start_new_dirmngr): Remove the system socket

* tools/gpgconf.c (list_dirs): Do not print "dirmngr-sys-socket".
* sm/server.c (gpgsm_server): Adjust for removed system socket feature.

(aService): Remove.

(w32_service_control): Remove.
(real_main, call_real_main) [W32]: Remove wrapper.
(main): Remove Windows system service feature.  Remove system dameon
feature.  Use only the "~/.gnupg/dirmngr_ldapservers.conf" file.
* dirmngr/certcache.c (load_certs_from_dir): Remove warning in the
system dameon case.
* dirmngr/crlcache.c (DBDIR_D): Always use "~/.gnupg/crls.d".
* dirmngr/ocsp.c (validate_responder_cert): Do not call
validate_cert_chain which was used only in system daemon mode.
* dirmngr/validate.c (validate_cert_chain): Always use the code.
--

We are now starting dirmngr as needed as a user daemon.  The
deprecated system daemon mode does not anymore make sense.  In case a
system wide daemon is required, it is better to setup a dedicated
account to run dirmngr and tweak socket permissions accordingly.

* g10/options.h (struct opt): Remove field tofu_db_format.
* g10/gpg.h (server_control_s): Add fields tofu.batch_update_ref and
tofu.batch_update_started.
* g10/gpg.c (parse_tofu_db_format): Remove.

* g10/tofu.c: Major rework.  Remove the pretty complicated and slower
split format and with that all the caching.  Use the dbs struct
directly.  Move global vars for batch update into CTRL.  Change
calling conventions of some function to take CTRL or DBS pointers
instead of  the former low-level database pointer.
--

The split database format might have been nice for use with Unison but
it bypasses the concept of a relational database by doing parts of
this itself and also risking deadlocks.  Working with the Tofu
database for debugging or experiments is also not possible with parts
of the database logic implemented in gpg.

The Tofu support is quite new and we can assume that it is not in real
use now.  Thus we better remove that now so that we do not need to
maintain it for all future.

* agent/command-ssh.c (ssh_handler_request_identities): Skip a key with
error, not giving up to handle the request itself.
* agent/cvt-openpgp.c (extract_private_key): Support "ecdsa" key.

--

Note that "ecdsa" key is still in use by old versions of gpg-agent
through its SSH handling (until 2.1.14).  With old versions of
gpg-agent, adding ECDSA key by ssh-add command, "ecdsa" key will be
created.  So, "ecdsa" key should be supported.

For g10/gpg, "ecdsa" and "ecdh" was only used in some experimental
versions of libgcrypt, with parameters.  We now use "ecc" for all cases
in released versions.

gpg: Avoid publishing the GnuPG version by default
* g10/gpg.c (main): initialize opt.emit_version to 0
* doc/gpg.texi: document different default for --emit-version

--

The version of GnuPG in use is not particularly helpful.  It is not
cryptographically verifiable, and it doesn't distinguish between
significant version differences like 2.0.x and 2.1.x.

Additionally, it leaks metadata that can be used to distinguish users
from one another, and can potentially be used to target specific
attacks if there are known behaviors that differ between major
versions.

It's probably better to take the more parsimonious approach to
metadata production by default.

  sm/sign.c, tools/gpgconf-comp.c, tools/gpgtar.h: replace "Allow to"
  with clearer text.

In standard English, the normal construction is "${XXX} allows ${YYY}
to" -- that is, the subject (${XXX}) of the sentence is allowing the
object (${YYY}) to do something.  When the object is missing, the
phrasing sounds awkward, even if the object is implied by context.
There's almost always a better construction that isn't as awkward.

These changes should make the language a bit clearer.
