base-name: optionally remove suffix.
The base-name function now takes a second argument which is
optional, specifying a suffix to be removed. The behavior is
similar to that of the second argument of the POSIX basename
command.
* stream.c (base_name): Second argument added. If present, the
returned value is adjusted by trimming the suffix, unless that
would cause an empty string to be returned.
(stream_init): Update registration of base-name intrinsic.
* stream.h (base_name): Declaration updated.
* txr.1: New base-name parameter documented.
