Remove malloc/free of android::ResTable_entry for inline overlay values. Add `target_entry_inline` to the idmap format to encode inline overlay values separate from direct mapping of target resource to overlay resource. This reduces the number of bytes needed to represent a direct mapping of target resource to overlay resource from 9 bytes to 8 bytes per entry. Fixed all idmap alignment issues that required the framework to use "#pragma pack(push, 1)" when loading idmaps. Bug: 170341022 Test: idmap2_tests and libandroidfw_tests Change-Id: Iab4d3902508f02773464724913e0ee966e3689e4
