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
