Overlay and target package paths can be longer than 256 characters. Currently, the idmap will fail to be generated if either path is longer than 256 characters. This change removes the 256 character limit and makes parsing variable length strings easier in libandroidfw. Bug: 174676094 Test: idmap2_tests && libandroidfw_tests Change-Id: Ic240cdb8700566b2ac2ade08da58bea852e4ae0c
