[bitbake-devel] [PATCH 2/7] bitbake: event: send the task dependency tree to UI

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

We add an event that will send the dependency tree
graph to the UI client once it is computed.

This will allow the clients to display dependency
data in an efficient manner, and not redo the runqueue
computation specifically to get the dependency data.
