- Variants/benchmarks can now be selected with wildcards
(--variant/--benchmark), and can be excluded from pruning
(--variant-exclude/--benchmark-exclude).
- The database clearing step can be skipped with --no-delete to
avoid deadlocks with concurrent DB accesses.
- Internals:
* injection_instr / injection_instr_absolute moves from
fspgroup to fsppilot. fsppilot now contains all information we
need for running FI experiments.
TODO: generic campaign needs to be modified, too.
* Force MySQL to use an efficient join order (STRAIGHT_JOIN).
