build: remove/suppress MSVC warnings

So we can enable "Treat warnings as errors"
+ added `verbose` parameter to vcbuild.bat

Removed/Silenced:
4005 - about redefinition of `PLATFORM` symbol
4996 - for the visible future I don't think we should be worried about the change in semantics of  `GetVersionEx`
4291 - for the `new` operator that has non side effects in FSReqWrap ```void *node::FSReqWrap::operator new(size_t,char *)```
4267 - when passing an int64 as int, and truncation might happen (depends on linkage)
4244 - when passing an int64 as int, and truncation will happen
4530 - no exception semantics (leaking from MS STL xlocale)
4221 - linker warning about object not exporting new symbols

align macros between dtrace and ETW removes warnings:
NODE\SRC\NODE_DTRACE.CC(180) : warning C4002: too many actual parameters for macro 'NODE_NET_SOCKET_READ'
NODE\SRC\NODE_DTRACE.CC(196) : warning C4002: too many actual parameters for macro 'NODE_NET_SOCKET_WRITE'
tools: benchmark + testing fix + cpplint.py

- Improve benchmark suite (can run all test)
- Improve test suite
- Update `cpplint.py` but exclude all new warnings
  - allows for c++11 as per https://groups.google.com/d/msg/v8-users/o1wffwdnUdU/EKzlsTDd-KgJ
