Summary: To avoid false positives, we treat `operator[]` in cpp as container read. Moreover, if a container `c` is owned, we make all accesses `c[i]` to be also owned.

Summary: Functions that do not belong to a class or a struct are translated to c-style functions even in the context of cpp. We need to add ownership to locals for c-style functions too.

Summary: `std::unique_lock` constructor allows to create a unique lock without locking the mutex. `std::unique_lock::try_lock` returns true if mutex has been acquired successfully, and false otherwise. It could be that an exception is being thrown while trying to acquire mutex, which is not modeled.

Summary:
Code often uses std::unique_lock::owns_lock to test if a deferred lock
using the 2-arg std::unique_lock constructor actually acquired the
lock.

Summary:
Use a distinct issue type for the Java and C++ concurrency analyses,
as the properties they are checking are significantly different.
