common: New function rfctimestamp.
* common/gettime.c (rfctimestamp): New.
--

It is surprisingly hard to create an RFC-2822 compliant Date value.
The problem is that strftime uses the current locale but the RFC
requires that the English names are used.  This code is pretty simply
and avoid the extra problem of figuring out the correct timezone;
instead UTC is used.  For the planned use case this is anyway better.

--

If a [/var]/run/user/$(id -u)/ directory exists, a gnupg subdir is
created as needed and the permissions of the directories are checked.
If that all matches that directory name is returned instead of the
homedir.

To cope with non standard homedirs (via GNUPGHOME or --homedir) the
SHA-1 hash of the homedir is computed, left truncated to 120 bits,
zBase-32 encoded, prefixed with "d.", and appended to
"[/var]/run/user/$(id -u)/gnupg/".  If that directory exists and has
proper permissions it is returned as socket dir - if not the homedir
is used.  Due to cleanup issues, this directory will not be
auto-created but needs to be created by the user in advance.

The required permissions are: directory owned by the user, group and
others bits not set.

Fix the ngettext/strcmp thing.  Use log_string instead of log_info.
Use NO_WARNING_THRESHOLD constant.
(get_trust): Use format_text and print a compact fingerprint.

The use of log_string makes long messages better readable; instead of

we now have

  gpg: Warning: if you think you've seen more[...]
       key, then this key might be a forgery![...]
       address for small variations.  If the [...]

We also put the key information after the message and not between the
user id and the last used info like here:

  gpg: Verified 7 messages signed by "Werner Koch <werner@eifzilla.de>"
       in the past 4 days, 16 hours.
       The most recent message was verified 3 days, 13 hours ago.
       (key: 8061 5870 F5BA D690 3336  [...] 1E42 B367, policy: auto)

This also makes the key info a separate translatable string.

Further a compact version of the fingerprint (hex w/o spaces) is
printed in some messages.

We should have a macro so that we do not need to define a wrapper
function like my_error_from_syserror in files where it is needed.  I
am not sure about a proper name, "my_" seems to be the easiest
replacement.  Note that the global DEFAULT_ERRSOURCE is relatively new
to replace the need to convey the error source in function calls; we
want that function from common/ return the error source of the main
binary.

We require that a key is ASCII and thus we better use ascii_strcasecmp
to avoid problems with strange locales.

It seems some compilers do not grok a re-declaration.  Thus we factor
it out into a separate file and use the include protection macro to
protect against re-declaration.

Function in common should use the error source of the component which
links them.  The global variable DEFAULT_ERRSOURCE is set early by
each component to make this possible.

Introduce a new iobuf type, IOBUF_INPUT_TEMP.  Use this for the iobuf
created by iobuf_temp_with_content instead of IOBUF_INPUT.  This was
necessary so that seeking and peeking correctly work on this type of
iobuf.  In particular, seeking didn't work because we discarded the
buffered data and peeking didn't work because we discarded data which
was already read, which made seeking later impossible.

Change the function so that caller can select canonical name of curve
or name for printing.  Suggested by wk.

Replace GNUPG_GCC_A_ macros by GPGRT_ATTR_ macros.
* common/util.h: Provide replacement for GPGRT_ATTR_ macros when using
libgpg-error < 1.20.
* common/mischelp.h: Ditto.
* common/types.h: Ditto.
--

Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places.  For now we need repalcement
macros, though.

This is the second and final part of the change to use the gpg
provided locale for Pinentry strings.  It does not yet work on
Windows, though.

pinentry-gnome3 talks to the gcr prompter via dbus.  Without this
environment variable, it can't find the correct session to talk to.

Static strings in gpg-agent need to be translated according to the
locale set by the caller.  This is required so that a gpg-agent can be
started in one locale and a gpg can be run in another.  If we don't do
this the static strings (prompt, buttons) are not or in the wrong
locale translated while dynamic strings (e.g. key description) uses
the locale of gpg.

This is only the first part of the change the actual local switching
still needs to be implemented.
