NLS handling fixes.

Hello. I found that backend's .po file has lines for GUC
descriptions but we won't see them anywhere.

The cause is GetConfigOptionByNum is fogetting to retrieve
translations for texts that have been marked with gettext_noop.

Regarding GUCs, group names, short desc and long desc have
translations so the attached first patch (fix_GUC_nls.patch) let
the translations appear.


Besides GUCs, I found another misuse of gettext_noop in
pg_GSS_recvauth. (2nd fix_GSSerr_nls.patch)

view_query_is_auto_updatable() and most of its caller are making
the same mistake in a similar way. All caller sites require only
translated message but bringing translated message around doesn't
seem good so the attached third patch adds _() to all required
places. (3rd fix_view_updt_nls.patch, 5th fix_vacuumdb_nls.patch)

psql is making a bit different mistake. \gdesc seems intending
the output columns names in NLS string but they actually
aren't. DescribeQuery is using PrintQueryResults but it is
intended to be used only for SendQuery. Replacing it with
printQuery let \gdesc print NLS string but I'm not sure it is the
right thing to fix this. (4th, fix psql_nls.patch)


plperl/plpgsql/tcl have another kind of problem in NLS. It
installs some GUC parameters and their descriptions actually have
a translation but in *its own* po file. So GetConfigOptionByNum
cannot get them. I don't have an idea to fix this for now.

regards.
