Subject: [PATCH] New frequency test, fixed error accounting, added logging
 timestamps, and miscellaneous smaller changes.

* Added a CPU Frequency test for select X86 processors to verify a minimum frequency is maintained during non-pause periods.
* Fixed the error accounting in WorkerThread::CheckRegion if more than 128 miscompares are found and when block errors are detected.
* Updated the logger to include timestamps and the associated timezone.
* Moved from apicid() to sched_getcpu() for determining the core ID.
* Added the ability to reserve a specified amount of memory. This can override the requested memory allocation.
* If not using POSIX shared memory or hugepages, explicitly mmap memory if the pagesize is 4kB otherwise use memalign.
* Removed the OSLayer's unused PCI device handling.
* Numerous refactoring changes.
