gpg: Pass CTRL to many more functions.
--

For proper operations as a server we need to avoid global variables.
Thus we need to pass the session state CTRL to most functions.  Quite
a lot of changes but fortunately straightforward to do.

gpg: Fix misleading log message when checking regexp.
* src/trustdb.c (check_regexp): Correctly print whether the
regexp matched or not.
--

This patch fixes the log message displayed when gpg attempts to
match the regexp associated with a trust signature with an user ID.
The current message interprets the 'ret' variable backwards, and
displays 'YES' when the regexp actually fails to match.

If the set of ultimately trusted keys changes, then it is possible
that a binding's effective policy changes.  To deal with this, we
detect when the set of ultimately trusted keys changes and invalidate
all cached policies.

I guess that is a left-over from an early attempt to output
information on the trustdb for use by other tools.  Maybe related to
the former --list-trust-path command.  Sending it to stdout is
probably useful so we do this now only in debug mode.

gpg(1) says:

              Try to be as quiet as possible.

While the mentions about the stale trustdb information are edifying,
they aren't necessary, and shouldn't be emitted when the user requests
--quiet.

Reported-by: Guilhem Moulin <guilhem@fripost.org>

  Needed for unattended key edits with --status-fd, because since 2.1
  status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
  not fflush(3), so the standard output may not be flushed before each
  prompt. (Which breaks scripts using select(2) to multiplex between
  the standard and status outputs.)

His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed.  This patch now
replaces most of them in g10/.  At some places stdio is still used,
but that is local to a function and should not have side effects.
