Breakpad Linux dumper: STABS reader incorrectly assumes a single compilation unit
The stabs reading code in google-breakpad incorrectly assumes that the
stabs data is a single compilation unit. Specifically, it ignores
N_UNDF stabs and assumes that all string indices are relative to the
beginning of the .stabstr section.
This is true when linking with the GNU linker by default, because the
GNU linker optimizes stabs debug info. The gold linker does not do
this optimization. It can be disabled when using the GNU linker with
the --traditional-format command line option.
For more details of the problem, see:

http://code.google.com/p/google-breakpad/issues/detail?id=359
This patch adds unit tests that reproduce the failure, and fixes the
stabs parser.
