	Introduce file_clearerr

	I'm unsure of this patch,

	gzclearerr() is used to clear the end-of-file mark, but for FILE
	there's function which do the same (clearerr).

	I created test program if clearerr() is needed for tailing file.
	and it seems to work without it (at least on Linux, so for
	!HAVE_LIBZ I commented it out).

	For now this patch introduce file_clearerr macro, and define it
	only when EOF marking must be cleared (i.e.  when HAVE_LIBZ and
	HAVE_GZCLEARERR are defined).

	So everything works like before, patch just to keep same prefix
	for file interface :)
