When pushing to the circular buffer, the read-offset mutex is no longer taken, so don't unlock the mutex. Don't allow writing to the last byte of the buffer. In that case, the read and write pointers will become equal and the buffer will be treated as empty. Add handling for pushing messages of invalid size.
