#5855: Optimize generic_ping function

--------------------------+-------------------------------------------------
 The `generic_ping` function currently sends weblog_ping() a null value if
 there is an empty line in the ping_sites option.  The regexp pattern in
 the function only replaces 2 or more empty lines with 1--it doesn't get
 rid of it altogether.  There's no check anywhere down the line to stop the
 IXR class from trying to ping an empty string.

 This restructure will address this problem and speed the function up at
 the same time.
