jimblandy 87855248f1 Breakpad symbol dumper: Move Linux dumping classes into src/common.
The Linux symbol dumper's classes are reasonably portable, and should be
usable for the Mac dumper as well. Move them to src/common, along with
their unit tests. Update #include directives and Makefile.

jimblandy c50e7c604c Breakpad Linux dumper: Add file comments as required by the style guide.
This also includes some comments I promised Cary Coutant I'd write
about the appropriateness of processing attributes in EndAttributes
calls.

The Google C++ Style Guide requires each file to have an author notice
and a comment explaining the file's general purpose. For the record, I
don't think putting an author notice on the files is a good idea; it's
odd to have the original author retain prominence even if the file has
been heavily edited by others; the version control system answers this
question more accurately. This is only for Style Guide compliance. The
Apache group decided to discourage author annotations, partially for
these reasons:

jimblandy 83e085b7a3 Breakpad: Update copyright notice years on all files changed in 2010.
We've gotten mixed advice from the lawyery types about whether this
matters. But it's easy enough to do.

jimblandy 5251e64f48 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.

jimblandy@gmail.com 7f941f990a Linux dumper: Add unit tests for google_breakpad::StabsReader.
The test system is based on Google C++ Testing Framework and the
Google C++ Mocking Framework.

This includes a parser that turns human-readable input files ("mock
stabs") into .stab and .stabstr section contents, which we can then
pass to a StabsReader instance, using a handler object written with
GoogleMock. The 'make check' target in src/tools/linux/dump_syms runs
this.

The supplied input file is pretty small, but I've done coverage
testing, and it does cover the parser.

I thought the mock stabs parser would be less elaborate than it turned
out to be. Lesson learned.
