data field is clubbed in with functions, shouldn't this be listed first?

Also should we call the field kUnsetThreadlocalKey?
or if you want to stick with Invalid make it
kInvalidThreadlocalKey so that it is obvious that the key is invalid not the
thread local value.

Moved field and changed name to kUnsetThreadlocalKey.
