This adds DWARF support to the Breakpad Linux dumper. This is
implemented as two handler classes: google_breakpad::DwarfCUToModule
accepts data from dwarf2reader::CompilationUnit, and
google_breakpad::DwarfLineToModule accepts data from a
dwarf2reader::LineInfo, each populating a google_breakpad::Module with
the results. Behaviors specific to particular source languages are
handled by instances of a new class, google_breakpad::Language.
An input executable may contain both STABS and DWARF debugging
information: the dumper automatically recognizes what sorts of
information are available, and integrates the data into a single
output file.
All classes have unit tests, providing line and branch coverage of all
interesting code. Unit tests are written using the Google C++ Testing
Framework, and the Google C++ Mocking Framework where appropriate.

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.
