(lazy_str): Fix for gc correctness: object from make_obj must be
completely intialized before any gc-triggering operation is invoked,
otherwise the garbage collector will be traversing an object
whose fields contain old garbage.
(lazy_str_force_upto): Off-by-one error. To force the object
up to index position N, means forcing up to length N+1.
This bug can make it look like a lazy string is much shorter
than it really is.

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.

Now numbers and characters fit into a cell. We lose one more bit
from the range of numbers.

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.

due to use of boxed numbers for vector access.

is needed for pipes that terminate abnormally or return failed
termination. Pipe and stdio streams have an extra description field
so they are printed in a readable way.

by the integer constant 0 rather than a proper null pointer constant.

bottom is unreliable due to the unpredictable allocation order of local

Regexps can be bound to variables.

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.
