8b3d0d1a36 common: Fix gnupg_inotify_has_name, differently.
* common/sysutils.c (gnupg_inotify_has_name): Use void * to stop the
warning.

--
According to the man page of inotify(7), it is aligned by null bytes.
So, bc28f320fa is reverted.

* common/sysutils.c (gnupg_inotify_watch_socket): Return
GPG_ERR_INV_VALUE for a missing socket name and set proper error

By using a different value we can easier see whether the error is due

When removing not a simple socket file but the entire directory the
old code missed most events and thus did not worked properly.

IN_DELETE_SELF has also been added to the watch list to detect a
removal of the directory.  However, in all tests that event was not
triggered.  The only way it could be triggered was by not watching
the socket dir but an arbitary directory and rmdir that.

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.

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.

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.

common: Minor fixes for the new private-keys.c.
* common/private-keys.c (my_error_from_syserror): New.  Use it in
place of gpg_error_from_syserror.
(_pkc_add, pkc_lookup, pke_next_value): Use ascii_strcasecmp.
(pkc_parse): Use xtrystrdup and append_to_strlist_try as intended.

(_pkc_add): Add braces around if-statement.

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.

GnuPG 2.3+ will use a new format to store private keys that is both
more flexible and easier to read and edit by human beings.  The new
format stores name,value-pairs using the common mail and http header
convention.

This patch adds the parser and support code and prepares GnuPG 2.1 for
the new format.
