Author: Andreas Huber <andih@google.com>
Date:   Mon Oct 26 16:11:54 2009 -0700

    DO NOT MERGE: Renaming string.h to stagefright_string.h to avoid conflicts.

commit 6738e306a50196f31a73d4fc7b7c45faff639903
Author: Andreas Huber <andih@google.com>
Date:   Thu Oct 15 13:46:54 2009 -0700

    DO NOT MERGE: Reimplement the OMX backend for stagefright.

    Besides a major cleanup and refactoring, OMX is now a singleton living in the media server, it listens for death notifications of node observers/clients that allocated OMX nodes and performs/attempts cleanup.

    Changed APIs to conform to the rest of the system.
