Move currentTime() from WebCore into WTF (to use in WTF::MessageQueue::WaitForMessageTimed)

• Component: Web Template Framework
• Status: RESOLVED FIXED

[Dmitry Titov]

Combined implementations of currentTime() from several platform-dependent files in WebCore/platform and from JSC/runtime/DateMath.cpp into JSC/WTF/CurrentTime.(h,cpp)

This brings all implementations close to each other, eliminates duplication and allows to sue currentTime() anywhere in the project, including WTF itself, in particulr to implement WTF::MessageQueue::WaitForMessageTimed and correct implementation of ThreadCondition::waitTimed() - those changes are following.

Proposed patch

Although there are many files, most of the files in this patch only have a different header file included.

Sentence fragment here. Also, I think it might be better to put this comment after the includes rather than in the middle of them.

I think some blank lines here would make it easier to read. The per-platform sections are large enough that a little more vertical whitespace will make it easier to spot the boundaries.
