Increase READ_BUF_SIZE, used in #'insert-file-contents-internal, to #x10000
src/ChangeLog addition:
2014-01-16 Aidan Kehoe <kehoea@parhasard.net>
* 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.
