	zlib.c: zstream_expand_buffer_non_stream

	* ext/zlib/zlib.c (zstream_expand_buffer_non_stream): rename from

	* ext/zlib/zlib.c (zstream_buffer_ungetbyte): simplify by using
	  zstream_buffer_ungets().
	zlib.c: no buf_filled in zstream

	* ext/zlib/zlib.c (zstream): manage capacity and size of `buf`
	  instead of size and separated member `buf_filled`.  reported by

	zlib.c: fix unnormalized Fixnum

	* ext/zlib/zlib.c (rb_gzfile_total_out): cast to long not to

  Skip two tests on AIX because zconf.h in zlib does not correctly
  recognize _LARGE_FILES in AIX. The problem was already reported
  to zlib, and skip these tests until it is fixed.
