Fix b/5317371 to make action-bar consistent with framework CAB.

1. Refactor to decouple ActionBar from FilterStackListener and
ActionBarListener to avoid FilterStack/Toolbar depending on ActionBar.
2. Recreate the action-bar on configuration changes and restore button
status and behaviors from the old action-bar.
3. Use framework CAB styles/dimensions to have consistent look and feel.
