w32: Remove unused code.

* jnlib/w32-reg.c (write_w32_registry_string): Remove.
w32: Always require libiconv.

* configure.ac (missing_iconv): Set and die if we have no libiconv.
* m4/iconv.m4: Update from libiconv 1.14.
* tools/Makefile.am (gpgtar_LDADD): Add LIBICONV.
* jnlib/utf8conv.c: Always include iconv.h
(load_libiconv): Remove this w32 only function.
(iconv_open, iconv, iconv_close): Remove W32 function pointer.
(set_native_charset): Do not call load_libiconv.
(jnlib_iconv_open, jnlib_iconv, jnlib_iconv_close): Ditto.

This patch removes the on-demand-loading of libiconv which we did for
13 years or so.  The rationale back then was that libiconv is too
large and often not used.  Nowadays all kind of Unix software has been
ported to Windows and many of them require libiconv.  Thus in the end
there is no saving from not requiring it.  It also remove a common
source of trouble with awrong or missing iconv.dll.

w32: Add code to support a portable use of GnuPG.

* common/homedir.c (w32_bin_is_bin, w32_portable_app) [W32]: New.
(check_portable_app) [W32]: New.
(standard_homedir, default_homedir) [W32]: Support the portable flag.
(w32_rootdir, w32_commondir) [W32]: Ditto.
(gnupg_bindir) [W32]: Ditto.
--

A portable use of GnuPG under Windows means that GnuPG uses a home
directory depending on the location of the actual binary.  No registry
variables are considered.  The portable mode is enabled if in the
installation directory of the the binary "gpgconf.exe" and a file
"gpgconf.ctl" are found.  The latter file shall be empty or consist
only of empty or '#'-style comment lines.

The dearmor code might create files in the source directory during a

agent: Fix UPDATESTARTUPTTY for ssh.

* agent/command-ssh.c (setup_ssh_env): Fix env setting.

gniibe reported this to gnupg-devel on 2012-07-04:

  [...]
  (2) UPDATESTARTUPTTY doesn't work to switch TTY for pinentry for
      SSH.

  [...]

  Current implementation:

      In the function start_command_handler_ssh, the logic puts
      priority on ctrl->session_env which is initialized by
      agent_init_default_ctrl.  There are always GPG_TTY and TERM
      defined, because lines around 968 in gpg-agent.c, it says:

  	/* Make sure that we have a default ttyname. */

      While UPDATESTARTUPTTY updates opt.startup_env, it doesn't
      affect at all.

  Here is a patch to point the issue.  Tested and works for me.

Require libgpg-error 1.11.

* configure.ac (NEED_GPG_ERROR_VERSION): Set to 1.11.
* common/util.h: Remove GPG_ERR_ replacements.
--

The replacement macros actually never worked because gog-error.h uses
enums and not macros.  libgpg-error 1.11 is 6 months old and thus it
should not be a problem to require that version.

Future replacement macros may then use the new
GPG_ERROR_VERSION_NUMBER to detect missing error codes.
