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.

pointer to a C static string, intended for literals. We can now
treat literal strings as light-weight objects.

use wide character functions so that there is no illicit
mixing. (But the goal is to replace this usage with txr streams).

This is incomplete. There are too many dependencies on
wide character support from the C stream I/O library,
and implicit use of some encoding which may not be UTF-8.
The regex code does not handle wide characters properly.
Character type is still int in some places, rather than wchar_t.
Test suite passes though.

unboxed. If the lowest bit of the obj_t * pointer is 1, then
the remaining bits are a number. A lot of assumptions are made:
- the long type can be converted to and from a pointer
- two's complement.
- behavior of << and >> operators when the sign bit is involved.

Lazy strings implemented, incompletely.
Changed string function to implicitly strdup; non-strdup
version changed to string_own. Fixed wrong uses of strdup
rather than chk_strdup.
Functions added to regex module to provide regex matching
as a state machine to which characters are fed.
