GetEnvironmentString does a UTF16ToUTF8 under the covers. how about making it
return a base::string16 from the get-go on windows, and require that other
consumers do the conversion? or add a second GetEnvironmentString that doesn't
do the conversion

[ananta, 2016/06/02 20:34:20]

Done. Added GetEnvironmentString16, SetEnvironmentString16 and
HasEnvironmentVariable16 for symmetry.

another spot where a string16 GetEnvironmentString makes sense

i was under the impression that this feature never launched. i can find no code
that calls this function. could you make this "return false;" and then remove
the function from the interface and all impls in a different CL?

[ananta, 2016/06/02 20:34:20]

Done.

Thanks. scottmg: could you confirm that my read is correct?

Yeah, I agree. I have no idea what that is, and it doesn't seem to be used.
