Big round of changes to switch the code base to use the stream

abstraction instead of directly using C standard I/O,
to eliminate most uses of C formatted I/O,
and fix numerous bugs, such variadic argument lists which
lack a terminating ``nao'' sentinel.

Bug 28033 is addressed by this patch, since streams no longer provide
printf-compatible formatting. The native formatter is extended with
some additional capabilities to take over.

The work on literal objects is expanded and they are now used
throughout the code base.

Fixed bad realloc in string output stream: reallocating by number
of wide chars rather than bytes.
