Various changes motivated by improving CFA score on len-1 queues.

No such CFA score improvement achieved. Each change helped only on stripped-down, "try to isolate an important factor" tests. Generally, the changes are benign refactorings. (Results substantiating "don't hurt" are forthcoming.)

Libcfa changes are

  • move a read action from between the memory breaks to before them
  • make the memory breaks conditionally excluded (default included, as before)

Harness changes are

  • add width, a compiled-in number of lists to use in round-robin order; defaults to 1, which is what was happening all along
  • make the analysis scripts tolerate (so far, ignore) the width column
  • rename CLI arg NumNodes to Length (now NumNodes is Length * Width)
  • factor core testing loops into helper function runtest
  • switch to signal-based termination (and add uC++ work-around)
  • put "iterator threading" into ITERS_SAVE, joining preexisting "save iter into elem's self ref"; make iterator threading conditional on iterators-active
  • disable insertion loop counter and obs_*-variable declarations (and thus writes) when observation disabled
  • generalize observation to work on multiple lists
  • make observation and assertion-check-enabled mode work on stripped CFA list implementations like tagging-disabled
  • through this observation, ensure correctness of multi-list versions
