[WIP] FastAdapter v3 refactor

[mikepenz]

TEST

You can currently try the v3 snapshot using the following dependency:

compile('com.mikepenz:fastadapter:3.0.0.7-SNAPSHOT@aar') {
    transitive = true
}
// 3.0.0.7-SNAPSHOT is also available for `fastadapter-commons`, `fastadapter-extensions`, `fastadapter-extensions-expandable`

WARNING not yet updated for v3.0.0.7
As the APIs changed quite a lot there are compat releases for the MaterialDrawer, and the AboutLibraries

compile('com.mikepenz:materialdrawer:6.0.0.6-SNAPSHOT@aar') {
        transitive = true
}
compile('com.mikepenz:aboutlibraries:6.0.0.6-SNAPSHOT@aar') {
        transitive = true
}

CHANGELOG

• the IAdapter and all it's implementation's are no extending RecyclerView.Adapter
• remove the concept of wrapping from the core library
• the FastAdapter will now directly be initialized with the adapters it should use (in addition you can add new ones at a later point)
• we no longer have an order in our adapters --> we no longer need a Footer or HeaderAdapter (just add your adapters in the order you need them)
• simplify AbstractAdapter
• simplify adapters access in the FastAdapter
• simplify DragDropUtil --> it only needs the ItemAdapter, as this one already notifies automatically when the move method is used
• temporary disable realm and firebase extensions
• move listeners and their implementations to seperate classes / files
• make sure the normal bindViewHolder call is not called if legacyBindViewMode is activated (to prevent twice the binds) ^^
  • this is anyways just a hack for the weird case of a library not properly implementing the onBindViewHolder method (in case we depend on the event being forwarded to us..)
• add FastAdapter to the OnCreateViewHolderListener methods so it is properly possible to get the handled TypeInstance from the viewType and it's parent
• add getEventHooks() method
• adjust sample with the moved Listeners
• adjust test as we need a view inside the ViewHolder to set the Tag
• update to new compatible MaterialDrawer SNAPSHOT
• implement initial Extension functionality
  • implement IAdapterExtension interface
  • implement ExpandableExtension
    • move all expandable depending logic to the extension
• update sample app and MaterialDrawer to support the extension
• fix test, as selectable has to be true to enable selecting
• remove the positionBasedStateManagement, it's just unnecessary code overhead, and hard to maintain
  • the identifierBasedStateManagement has many advantages and it's only overhead is that we have to run once over the whole list of items (in the worst case)
• fix issue with the SelectExtension not getting properly initialized
• simplify getSelectedItems and getSelections
• remove no longer needed util functions
