[PATCH] oe.types: add 'path' type

[PATCH] oe.types: add 'path' type

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

- path normalization ('normalize' flag, defaults to enabled)
- existence verification for paths we know should exist ('mustexist' flag)
- supports clean handling of relative paths ('relativeto' flag)
