[PATCH] D17549: More UTF string conversion wrappers

(And a missing string conversion for getenv on Win32, too.)

These new string conversion wrappers convert between std::string (of UTF-8 bytes) and std::wstring, which is particularly useful for Win32 interop.

The motivation behind this is to support a patch I'm preparing for LLDB (the first version of which is at D17107) that makes heavy use of these helper functions for better Unicode support on Windows.
