idmap2 is a reboot of the idmap project. The project aims to - use modern C++ - greatly improve test and debug support - interface towards AssetManager2 (instead of AssetManager) - provide a solid foundation to add support for new features To make it easier to verify correctness, this first version of idmap2 is feature equivalent to idmap. Later versions will add support for new features such as <overlayable>. Bug: 78815803 Test: make idmap2_tests Change-Id: I1d806dc875a493e730ab55d2fdb027618e586d16
