Modified Files:
        src/lib/libc/stdlib: setenv.c

Log Message:
Simplify and KNF. Instead of keeping track if the pointer was allocated,
keep a copy of the pointer itself and only re-use it if the current
environment is equal to the saved pointer. Idea from OpenBSD. Avoids
problem of re-allocing a non-allocated pointer if a program resets the
environment after it has been grown.
