We freed PL_splitstr in each thread, allocate it in each thread too

I also fixed const correctness for PL_splitstr, it was initialized
to " " which required it to be const, but the value is only looked
at when PL_minus_F is true, so it wasn't necessary.

So initialize it to NULL, and duplicate the value in threads.
