[beast/win32] Move browser start function to Birnet::OS. Provide win32 version.

[Stefan Westerfeld <stw src gnome org>]

commit c95a47b87dd5412827b96cb1fadfd10cebb1ff9a
Author: Stefan Westerfeld <stefan space twc de>
Date:   Thu Nov 19 10:03:03 2009 +0100

    Move browser start function to Birnet::OS. Provide win32 version.
    
    * birnet/birnet*[hc]: Make browser start working on windows by moving the
    browser start code from birnetutils.cc to birnetosunix.cc, and by adding
    a new browser start function based on the win32 API to birnetoswin32.cc.
    
    * sfi/sfiwrapper.cc: Use Birnet::OS::url_test_show function which works
    on win32 and unix.
