Windows: Kill the dedicated thread for monotonic clock_gettime()

According to Microsoft, anything prior to Vista could provide
inconsistent results for the value of QueryPerformanceCounter() across
different cores. Now that XP is no longer supported, we can drop the
significant overhead of using a dedicated thread pinned to a single core
just to read a timestamp.

The C++11 steady_clock implementation directly wraps
QueryPerformanceCounter(), so if it is good enough for that then it is
good enough for our purposes.

Build Status Build status Coverity Scan Build Status

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD and Haiku userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).

libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
