Commit Message

Fix BlistList for two ranges

Several results were wrong, and had been wrong since at least GAP 4.4.
E.g. before this commit:

    gap> BlistList([0..3], [-3..-1]);
    [ true, true, true, false ]

Now we get the correct result

    gap> BlistList([0,1,2,3], [-3..-1]);
    [ false, false, false, false ]

One major issue was the use of unsigned variables to store signed data. Two
variables were only of type `long` instead of `Int`, but on 64bit, this could
lead to further issues.

The logic handling the intersection was broken and overly complicated. The
rewritten logic should be simpler.

Finally, there is a tiny optimization enabled by switching from 1-based
indexing to 0-based.
