Fix deadlock when setting environment variables.
Qt uses QHash as the container for faking environment variables on
Windows Runtime and CE. Environment variable manipulation functions are
protected by mutex. Accessing the QT_HASH_SEED environment variable
inside QHash can lead to situation where qputenv() call leads to
qgetenv() call and that leads to a deadlock. Since the application
environment is faked anyway, drop support for QT_HASH_SEED and ifdef
that functionality out on those platforms. Documentation is updated
to reflect changes.
