Make get/putenv and erlexec understand Unicode

Putenv and getenv needs to convert to the proper environment
strings in Unicode depending on platform and user settings for filename
encoding. Also erlexec needs to pass environment strings in an appropriate
way for kernel to pick up. All environment strings on the command
line, as well as home directory, is now passed in UTF8 on windows
and in whatever encoding you have on Unix, kernel tries to convert all
parameters and environments from UTF8 before making strings.
