* Updated APIs in the file generic/tclIO.c according to the guidelines

        of TIP 27.  Several minor documentation corrections as well.

	* Updated channel driver interface according to the guidelines of
	TIP 27.  See also [Bug 500348].

	* Moved Tcl_EolTranslation enum declaration from generic/tcl.h to
        generic/tclInt.h (renamed to TclEolTranslation).  It is not used
        anywhere in Tcl's public interface.
