Yonggang Luo 296eb2918c util: Remove the need of _MTX_INITIALIZER_NP in simple_mtx.h 
The usage of _MTX_INITIALIZER_NP is a problem. Sure, the code builds on
Linux and Windows, and it even usually works, but is problematic.
It means that Windows lock debugging tools cannot be used with that code.
So we remove _MTX_INITIALIZER_NP to gain the following benefit:
  Aligning to the C11 standard threads.h definitions.
  Improving portability of the threading code to better support Windows.
This change removes one of the most prolific uses of _MTX_INITIALIZER_NP by
slightly increasing the cost of simple_mtx_lock when targeting platforms that
don't support futex, but it's cost are far less than the cost of syscall,
so the affect are negligible.

The futex code path are not affected. And Windows 8 and upper also
supports the futex codepath, so it's only affect the Windows version < 8, MacOS
or other platforms that doesn't support for futex.
