[webkit-qt] WebKit2, PluginProcess and LightHouse

[keith.kyzivat at nokia.com]

Right now you should be able to achieve a Qt Lighthouse webkit build by doing the following, without any code changes:
Tools/Scripts/build-webkit --makeargs=\"-j4\" DEFINES+=PLUGIN_ARCHITECTURE_UNSUPPORTED=1 DEFINES+=ENABLE_NETSCAPE_PLUGIN_API=0

I just ask for things to compile and properly fail (e.g. disabling
plugins).

Today: To fix build of WebKit2 for Qt/E I do:

diff --git a/Source/WebKit2/config.h b/Source/WebKit2/config.h
index 39ec8d9..68d5430 100644
--- a/Source/WebKit2/config.h

 #define PLUGIN_ARCHITECTURE_X11 1
 #else
 #define PLUGIN_ARCHITECTURE_UNSUPPORTED 1


Future:
  Q_WS_ will not be there anymore, OS(UNIX) is a bad indication
  to see if X11 headers are installed. Do we need to add detection
  for X11 headers to our buildprocess then?

  To me it looks like the PLUGIN_ARCHITECTURE check needs to become
  a runtime check, because only at runtime we know if we are running
  on Xlib/Xcb or on something like Wayland? How do we detect the
  used QPA platform at runtime?
