hashtable: preparations to use hexport_r() for "env grep"
The output of "env grep" is unsorted, and printing is done by a
private implementation to parse the hash table. We have all the
needed code in place in hexport_r() alsready, so let's use this
instead. Here we prepare the code for this, without any functional
changes yet.
