IMPALA-3748: add query-wide resource acquisition step This adds a PrepareForExecution() method to QueryState that allow query execution to fail up-front if resources cannot be acquires. We don't make full use of this yet, but it provides a suitable place to acquire a memory reservation for the query or fail cleanly. The process memory limit check is moved here so that all startup memory checks will be eventually consolidated in one place. Also switch a boost::mutex to a SpinLock for consistency and to improve performance (see lock-benchmark.cc).
