bitbake: layerindexlib: Initial layer index processing module implementation

The layer index module is expected to be used by various parts of the system
in order to access a layerindex-web (such as layers.openembedded.org) and
perform basic processing on the information, such as dependency scanning.

Along with the layerindex implementation are associated tests.  The tests
properly honor BB_SKIP_NETTESTS='yes' to prevent test failures.

Tests Implemented:
   - Branch, LayerItem, LayerBranch, LayerDependency, Recipe, Machine and
      Distro objects
   - LayerIndex setup using the layers.openembedded.org restapi
   - LayerIndex storing and retrieving from a file
   - LayerIndex verify dependency resolution ordering
   - LayerIndex setup using simulated cooker data

+This test data is used to verify the 'cooker' module of the layerindex.
+
+The module consists of a faux project bblayers.conf with four layers defined.
+
+layer1 - openembedded-core
+layer2 - networking-layer
+layer3 - meta-python
+layer4 - openembedded-layer (meta-oe)
+
+Since we do not have a fully populated cooker, we use this to test the
+basic index generation, and not any deep recipe based contents.
