Fix WebRtc ninja x86 build using Visual Studio 2015 (set GYP_MSVS_VERSION=2015).

Visual Studio 2015 balks at the implicit truncation of values. Easily fixed with an explicit cast.

Fixed redefinition of CLOCKS_PER_SEC when using Visual Studio 2015 and the Windows 10 SDK. CLOCKS_PER_SEC is also defined in "<WIN10 SDK DIR>\include\10.0.10240.0\ucrt\time.h" and also has the value of 1000

Hiding snprintf definition if building with Visual Studio 2015

Fixed C4573 compiler complaint in audio_processing_impl_locking_unittest.cc.
