Support case insensitive treatment of os.environ keys on Windows and
DOS (as well as OS/2). I presume that making a call to putenv() with a lowercase key will actually do the right thing. I know this is so on Windows/DOS, and I expect it is so OS/2 -- but the old OS/2 code didn't assume this. (I don't know if the person who provided the OS/2 patch was clueless or just didn't care about DOS and Windows.) Also ripped out the support for pickling -- as of 1.5, this is no longer needed to make pickling work.
