softpipe: use 64-bit arithmetic in softpipe_resource_layout()

To avoid 32-bit integer overflow for large textures.  Note: we're
already doing this in llvmpipe.

mapi/u_thread: Use GetCurrentThreadId

u_thread_self() expects thrd_current() to return a unique numeric ID
for the current thread, but this is not feasible on Windows.

c11/threads: Don't implement thrd_current on Windows.

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.
