GetCurrentThread() returns a pseudo-handle (a constant which only makes
sense when used within the calling thread) and not a real handle.
DuplicateHandle() will return a real handle, but it will create a new
handle every time we call. Calling DuplicateHandle() here means we will
leak handles, which can cause serious problems.
In short, the Windows implementation of thrd_t needs a thorough make
over, and it won't be pretty. It looks like C11 committee
over-simplified things: it would be much better to have seperate objects
for threads and thread IDs like C++11 does.
For now, just comment out the thrd_current() implementation, so we get
build errors if anybody tries to use it.
Thanks to Brian Paul for spotting and diagnosing this problem.

Implementation is based of https://gist.github.com/2223710 with the
following modifications:
- inline implementatation
- retain XP compatability
- add temporary hack for static mutex initializers (as they are not part
of the stack but still widely used internally)
- make TIME_UTC a conditional macro (some system headers already define
it, so this prevents conflict)
- respect HAVE_PTHREAD macro
