Fix build when using Visual Studio 2015 Update 1. Many of the compatibility issues are described at https://msdn.microsoft.com/en-us/library/mt612856.aspx. The macros that suppressed warnings on a per-function basis no longer work in Update 1, so replace them with #pragmas. Update 1 warns when |size_t| arguments to |printf| are casted, so stop doing that casting. Unfortunately, this requires an ugly hack to continue working in MSVC 2013 as MSVC 2013 doesn't support "%zu". Finally, Update 1 has new warnings, some of which need to be suppressed. --- Updated by davidben to give up on suppressing warnings in crypto/x509 and crypto/x509v3 as those directories aren't changed much from upstream. In each of these cases, upstream opted just blindly initialize the variable, so do the same. Also switch C4265 to level 4, per Microsoft's recommendation and work around a bug in limits.h that happens to get fixed by Google include order style. (limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some other headers, is included before it. The reason it affected just one file is we often put the file's header first, which means base.h is pulling in stddef.h. Relying on this is ugly, but it's no worse than what everything else is doing and this doesn't seem worth making something as tame as limits.h so messy to use.)
