Linux dumper: Let LineInfo structures point directly to their SourceLineInfo structures
Linux dumper: Let LineInfo structures point directly to their SourceLineInfo structures

Let LineInfo structures point directly to their SourceLineInfo
structures, rather than holding the index of the file's name in the
.stabstr section in the early phases, and then later the holding
source_id of the file.

This is another step in the process of moving STABS-specific values
out of the types that represent the breakpad symbol data.  When we're
done, the non-STABS structures will be something that we can populate
with both STABS and DWARF data --- or at least it will be more easily
replaced with such.
