Comment:

 Ready for review.

 My system's valgrind does not detect all cases newer versions do, but
 still, these changes reduced the suppressions file I get from 8867 lines
 (608 suppressions) to 224 lines (8 suppressions)

 Most of the changes are pretty straightforward I think.

 A couple of the memsets could technically be a little more specific (for
 instance take into account which data we know we will write, and only
 blank the rest), but it seemed more prudent to initialize the entire thing
 first.

 For most directories in src/lib the unittests *should* now pass with
 valgrind without any suppressions. A few notable exceptions are
 - any sets that contain death tests (valgrind goes bonkers on those, and
 probably rightfully so)
 - lib/resolver tests (need some serious rework of either the resolver or
 the test setup due to classes that are supposed to delete themselves)
