winsup/doc: Generate ANSI rather than K&R style function prototypes

Since K&R style prototypes appear to be the default for HTML and FO, customize
the stylesheets rendering of funcsynopsis elements to generate ANSI style
prototypes instead.

2015-06-17  Jon Turney  <jon.turney@dronecode.org.uk>

	* fo.xsl: Render funcsynopsis elements as ANSI style function
	prototypes.
	* html.xsl: Ditto.
