Don't include print-copyr.h.

(prepare_input_buffer): Renamed from prepare_record_buffer.
New arg FD.  All uses changed.
Do not read more than INT_MAX bytes at once,
since it breaks on some brain damaged Tru64 hosts.
Do not mix int and size_t pointers.  Divide size by two
when retrying instead of subtracting 1024; for speed.
(main): Use gettext to translate (C), not print_copyright.
