change function headers to K&R style

Another huge change, for PEAR code standards compliance. Function
headers have to be in K&R style (opening brace on its own line),
instead of having the opening brace on the same line as the function
and parameters. So, a little perl magic found all the function
definitions and move the opening brace to the next line (properly
indented... usually).
