import-trace: import debug info

Browse Source 
If the --debug option is set, the line number table of the elf binary will
be imported into the database. The information will be stored in the
"dbg_mapping" table.

If the --sources option is set, the source files will be imported
into the database. Only the files that were actually used in the
elf binary will be imported.

The ElfImporter calls objdump and dissassembles an elf binary
and imports the results into the database
In addition, debugging information can be imported:
If the --sources option is set, the source files will be imported
into the database. Only the files that were actually used in the
elf binary will be imported.
