- Add a method to get the max size of an elf file by reading the section header offset + size. This will properly map an elf file embedded into an apk, instead of just mapping in what is done by the dynamic linker. It does assume that the section headers are at the end of the elf file. - Add new tests for the above functionality. - Update the unwind_symbols tool to take an address for finding a function instead of dumping the entire symbol table. Bug: 23762183 Test: Unit tests pass, unwind through the camera process and verify Test: the GoogleCamera.apk shows some function names. Change-Id: I00c021680fe1d43b60d652bf91bbf6667d9617be
