[PATCH v3 02/21] Move stdtarg to ui

[Tom Tromey <tom@tromey.com>]

Currently, most of the output streams are handled by the UI -- with
the sole exception of gdb_stdtarg.  This doesn't make sense to me, and
it is is useful in the longer term to make it per-UI so that the
logging approach can be uniform across all streams.  So, this moves it
to the UI, following the implementation approach of all other output
streams.
