New: mkdtemp and mkstemp functions.

* configure: check for mkstemp and mkdtemp.

* stream.c (stdio_set_prop): Implement setting the :name
property. We need this in mkstemp_wrap in order to punch in
the temporary name, so that the application can retrieve it.
(mkdtemp_wrap, mkstemp_wrap): New functions.
(stream_init): Register mkdtemp and mkstemp intrinsics.

* stream.h (mkdtemp_wrap, mkstemp_wrap): Declared.

* txr.1: Documented.

* share/txr/stdlib/doc-syms.tl: Updated.
