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.

+ *
+ * Strategy for importing traces into the MySQL Database, that cover
+ * only kernel space data address. A single trace is only added to the
+ * database, if it has the following form:
+ *
+ * - The memory access is after the kernel has passed the
+ *   getEnterKernelAddress(), before it passes the
+ *   getLeaveKernelAddress() again. Short: if the programm is in
+ *   kernel space.
+ * - Only memory addresses that are located in the os::data::dynamic
+ *   namespace
+ * - Only memory accesses to addresses that were not written in the
+ *   current kernel space phase.
