Implement ThreadCondition::timedWait().
Since we borrow the code for condition variables from other sources,
I did the same for timedWait(). See comments in ThreadingWin.cpp for
rationale and more info.

• wtf/CONTRIBUTORS.pthreads-win32: Added. A list of Pthreads-win32 contributors mentioned in their license. The license itself is included into wtf/ThreadingWin32.cpp.

• wtf/Threading.h:
• wtf/ThreadingWin.cpp: Additional info and Pthreads-win32 license at the beginning. (WTF::PlatformCondition::timedWait): new method, derived from Pthreads-win32. (WTF::PlatformCondition::signal): same (WTF::ThreadCondition::ThreadCondition): (WTF::ThreadCondition::~ThreadCondition): (WTF::ThreadCondition::wait): this now calls PlatformCondition::timedWait. (WTF::ThreadCondition::timedWait): same (WTF::ThreadCondition::signal): this now calls PlatformCondition::signal. (WTF::ThreadCondition::broadcast): same
