d984d32588 New constructor make_bool avoids boilerplate. 
Hash function takes a length so that it (1) it can support strings containing NULs; (2) it doesn't have to check for NULs so runs a bit faster; and (3) it performs OK on addresses (which often contain zero bytes).
Hash tables have hash and comparison functions.
Implement string=?, make-eqv-hashtable and make-hashtable.

e11e83d909 Amc can't omit the guard "segrankset(seg) != ranksetempty" for calling segsetgrey, because amcz uses segments with an empty rank set. 
It's OK to call SegSetGrey on a segment with an empty rank set so long as you are not actually setting it to be grey for any traces, so correct the AVER accordingly.
