Patch for Sean Evoy

In order to work through CExtensionPoint mechanism, I have to change the 
existing extension point entries for the Managed and Standard builders to 
the following (all future builders will have to conform to this as well):
   <extension
         id="ManagedBuildManager"
         point="org.eclipse.cdt.core.ScannerInfoProvider">
      <cextension>
         <run
 class="org.eclipse.cdt.core.build.managed.ManagedBuildManager">
         </run>
      </cextension>
   </extension>

   <extension
         id="StandardBuildManager"
         point="org.eclipse.cdt.core.ScannerInfoProvider">
      <cextension>
         <run
 class="org.eclipse.cdt.core.build.standard.StandardBuildManager">
         </run>
      </cextension>
   </extension>

As well, the ManagedBuildManager and StandardBuildManager must extend 
AbstractCExtension.

The new project wizards for managed and standard projects have to be 
modified to register the right class as the scanner info providers for the 
project. The example below shows the managed project wizard code, but the 
standard project wizard is similar.
try {
        ICDescriptor desc = 
CCorePlugin.getDefault().getCProjectDescription(project);
        desc.remove(CCorePlugin.BUILD_SCANNER_INFO_UNIQ_ID);
        desc.create(CCorePlugin.BUILD_SCANNER_INFO_UNIQ_ID, 
ManagedBuildManager.INTERFACE_IDENTITY);
} <snip>


Clients use a new method defined in CCorePlugin 

public IScannerInfoProvider getScannerInfoProvider(IProject project) {
        IScannerInfoProvider provider = null;
        if (project != null) {
                try {
                        ICDescriptor desc = (ICDescriptor) 
getCProjectDescription(project);
                        ICExtensionReference[] extensions = 
desc.get(BUILD_SCANNER_INFO_UNIQ_ID);
                        if (extensions.length > 0)
                                provider = (IScannerInfoProvider) 
extensions[0].createExtension();
                } catch (CoreException e) {
                }
        }
        return provider;
}

to get the information provider as shown in the updated JUnit test code 
below:
// Find the first IScannerInfoProvider that supplies build info for the 
project
IScannerInfoProvider provider = 
CCorePlugin.getDefault().getScannerInfoProvider(project);
assertNotNull(provider);

As is the case now, clients implement the IScannerInfoChangeListener 
interface and pass themselves to the provider in a subscription message. 
There is also a new method on the IScannerInfoProvider interface that 
allows the client to get information immediately as shown below:
IScannerInfo currentSettings = provider.getScannerInformation(project); 

The ManagedBuildManager::getScannerInfo(IResource) method will be 
deprecated, then removed before the end of this release cycle.
