Support for pushing back bytes and characters into streams.
* stream.c (null_ops, stdio_ops, tail_ops, pipe_ops,
string_in_ops, byte_in_ops, string_out_ops, strlist_out_ops,
dir_ops, cat_stream_ops): Structure definition updated
with new initializers for two new virtuals.
(stdio_handle): New member, unget_c.
(snarf_line, stdio_get_char): Handle pushed-back character in
h->unget_c.
(stdio_unget_char, stdio_unget_byte, string_in_unget_char,
byte_in_unget_byte): New static functions.
(make_stdio_stream_common): Initialize unget_c member.
(unget_char, unget_byte): New functions.
* stream.h (struct strm_ops): New virtuals: unget_char and unget_byte.
(unget_char, unget_byte): New functions declared.
* syslog.c (syslog_strm_ops): Two new initializers.
* eval.c (eval_init): Registered unget_char and unget_byte as
intrinsics.
* txr.1: Documented.
