Add multithreading test for SamplingCircularQueue, fix implementation.
...
This is for the case of Linux, where sampling is done using SIGPROF
signal handler which is executed in the context of an interrupted
thread. In this case, my previous implementation with TLS doesn't
work.

Implement circular queues for the C++ version of CPU profiler.
...
Circular queues serve as a transport for communicating between
VM, stack sampler and analyzer threads. Logging requirements
for VM and stack sampler are completely different, that's why
I introduced two different versions of CQs.
