Replaces the extension in \p buf of max.<br>
size \p buflen with the extension in \p ext.<br>
If there's no '.' in \p buf, \p ext is appended.<br>
If \p ext is NULL, behaves as if it were an empty string ("").
\b Example
\code
#include <FL/filename.H>
[..]
char buf[1024] = "/path/myfile.cxx";
fl_filename_setext(buf, sizeof(buf), ".txt"); // buf[] becomes "/path/myfile.txt"
\endcode
\return buf itself for calling convenience.
