tools/import-trace: new tool to import traces into MySQL database

The import tool does support the following import strategies:

- BasicImporter: generates def-use equivalence classes for read and
  write memory accesses
- DCiAOKernelImporter: generates equivalence classes for read access in
  the ciao kernel space.
