Windows build errors

[lo-simon]

Hi there

We have taken the advice in #1277 for building the Window Media Transport Library.

We want to get your expertise to confirm that our patches are sufficient to build the DPDK and the Media Transport Libraries for Windows.

Here are two areas we found in the build process.

1. Failed with error: GUID_DEVCLASS_NETUIO is undeclared (using MIGW64).

2. Failed with error: redefinition of clock_gettime
   To prevent the redefinition of 'clock_gettime' issue, we added a test condition in win_posix.h and win_posix.c to #define out the clock_gettime in MINGW64 build. For building the applications, we have modified the include path to include win_posix.h.
   fix-MTL-windows-MinGW.patch
