Summary:     Increase READ_BUF_SIZE, used in #'insert-file-contents-internal, to #x10000

src/ChangeLog addition:

2014-01-16  Aidan Kehoe  <[email protected]>

	* fileio.c (READ_BUF_SIZE):
	Stack sizes > 2**16 elicited bugs back in August 1996, but there's
	nothing to indicate this is still the case. GNU uses a block size
	of #x10000, and that size works better with the coding system
	buffering, improving performance there; move to this value.
Affected #:  2 files
