Initial pass at simple event tracing. I added a few traces to tcp_socket and test_shell to get an idea of what a simple trace might look like.

Here's a sample output line:
11:24:19.660604 0x1e278:0x1e24c BEGIN url.load [0x5 http://mail.google.com/mail/] <E:\src\cr\src\webkit\tools\test_shell\test_webview_delegate.cc:189>

format is:hh:mm:ss.us pid:tid TYPE NAME [id, extra] <file:line>
