From bf776679a73f3b9eae37aabd2be5754483039cb2 Mon Sep 17 00:00:00 2001

Subject: patman: Move to absolute imports

At present patman sets the python path on startup so that it can access
the libraries it needs. If we convert to use absolute imports this is not
necessary.

Move patman to use absolute imports. This requires changes in tools which
use the patman libraries (which is most of them).
