Add an agent-based lock inversion checker. The agent will dynamically rewrite bytecode to inject calls to LockHook, which runs a checker on these. Implement a simple on-thread checker that keeps a per-thread stack of locks and a global map of lock ordering. As-is, transitivity of checks is not guaranteed, but should be captured in most practical cases. To run a process with the lock checker, start the process with the agent. The helper script start_with_lockagent.sh can be used for this: adb shell setprop wrap.pkg-name script start_with_lockagent (cherry picked from commit aeb6fce5b33680bc538dbd66979a28bcba1329b4) Bug: 124744938 Test: manual Merged-In: Idd9a7066a5b8cb8c0de2e995f08759c98d9473e1 Change-Id: Idd9a7066a5b8cb8c0de2e995f08759c98d9473e1
