The refactoring part involves moving as much as possible stuff
in SdkLib/internal/repository.
The UI has moved in SdkUiLib/internal/repository except a specific
public wrapper for calling the Sdk Updater window.
There are also a bunch of new classes to handle the internal
structures: Package is the base type and to match the XML element
names we have PlatformPackage, AddonPackage, DocPackage and
ToolPackage.
All headers have been fixed.
Used to display the AVD Manager from the Device Chooser/Launch config.
Used to delete AVDs from the AVD Manager.
In AVD Manager, also hide the Cancel button since actions are
immediate and not cancelable.
This happens when you open the Windows > Prefs > Android panel
while an SDK is initially loading or when you change the
SDK in the pref panel. The target change listener was not
properly removed since the field was not properly disposed.
This also removed the multiple selection handling in the
SdkTargetSelector, which we never use. In the unlikely event
we want to use it later, it would be trivial to add it back.
