gpg: Replace remaining uses of stdio by estream.

* g10/sign.c (sign_file):  Use log_printf instead of stderr.
* g10/tdbdump.c (export_ownertrust): Use estream fucntions.
(import_ownertrust): Ditto.
* g10/tdbio.c (tdbio_dump_record): Ditto.  Change arg to estream_t.

  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.
