* io.c (read_all): do not return nil at the end of file.

Browse source 
[ruby-dev:22334]

* io.c (argf_read): do not depend on nil at eof behavior of
  IO#read().

* eval.c (rb_thread_join): dup exception before re-raising it.

* io.c (rb_io_eof): call clearerr() to prevent side effect.  this
  patch is supplied by Masahiro Sakai <sakai@tom.sfc.keio.ac.jp>.
  [ruby-dev:22234]

* pack.c (OFF16): get offset for big endian machines.

* pack.c (pack_pack): use OFF16 instead of OFF16B.
  [ruby-dev:22344]

* pack.c (pack_unpack): ditto.
