This extends the ElfArchitecture function to recognize the
architectures it seemed to me that breakpad was most likely to see.
Also: the dumper has historically not provided very helpful error
messages. This patch adds a few that were convenient, but we should do
an audit for this.

Style Guide.
The Google C++ Style Guide says that members of structures needn't
have names ending in underscores. The structure types in
google_breakpad::Module don't follow this rule.

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.

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://sourceware.org/bugzilla/show_bug.cgi?id=10338
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.

Previous patches added unit tests for the STABS parser and the
Breakpad symbol file writer; this adds unit tests for the "dumper"
class that sits between them, receiving data from the parser and
handing it to the writer. So now the whole pathway has coverage.

Adjust Module's interface a bit to facilitate testing:
- Make AssignSourceIds something a client can call --- it's perfectly
well-defined, so this is an okay change.
- Add GetFunctions, GetFiles and FindExistingfile member functions,
which the test harness will use to get results to examine.

guid_creator.cc.
Building on Ubuntu 9.10 with the distributed compiler (GCC 4.4.1), we get
warnings like the following:
guid_creator.cc:56: warning: dereferencing type-punned pointer will break strict-aliasing rules
It doesn't matter in this case, but there's no crying need to use
reinterpret casts in an endian-dependent way when there are plenty of
well-defined ways to get the same effect.

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.

If the input passed to a StabsReader instance contains a compilation
unit whose first entry is an N_SO with no name, the parser enters an
infinite loop. Since such entries mark the end of a compilation unit,
ProcessCompilationUnit should skip them.

src/linux/common/module.h defines a new class, google_breakpad::Module,
that can represent the contents of a breakpad symbol file. Module::Write
writes a well-formed symbol file to the given stream.
src/linux/common/dump_symbols.cc can now lose its symbol-file-writing
code, and change DumpStabsHandler to populate a Module object, rather
than the old SymbolInfo/SourceFileInfo/... collection of types.
The code to compute function and line sizes, even in the absence of
reliable size data in STABS, is moved into a new Finalize method of
DumpStabsHandler, which is responsible for completing the Module's
contents.

With this patch, dump_symbols.cc no longer knows about the details of

char *.
Because the actual N_FUN strings in the .stabstr section contain type
information after the mangled name, representing this information
using a pointer into .stabstr, while efficient with memory, makes the
FuncInfo data structure STABS-specific: one must know the details of a
STABS N_FUN string's syntax to interpret FuncInfo::name. This patch
removes this STABS dependency from the data structure, and moves us
closer to having an appropriate structure for representing unified
STABS and DWARF data.

STABS strings for N_FUN entries contain a mangled function name,
followed by a colon, followed by type information. The type
information itself may contain colons; mangled names never contain
colons (they need to be legal assembly-language identifiers). So the
current code in src/common/linux/dump_symbols.cc:WriteOneFunction that
attempts to separate the mangled name from the STABS junk will
incorrectly include STABS junk in the name, causing demangling to
fail.
Applying the patch below results in changes like these in the symbol
file produced, where an unmangled name followed by STABS junk becomes
a properly demangled name:

In STABS, if one function's line number information contains an N_SOL
entry to switch to a new source file, then the next function's line
data should pick up in the same source file where the prior function
left off. However, the Linux dumper restarts each function in the
compilation unit's main source file. This patch fixes that, so that
the output attributes the lines in subsequent functions to the correct
source files.

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.

SourceFileInfoList entries.
STABS information introduces a compilation unit with an N_SO entry
whose address is the start address of the file and whose string is the
name of the compilation unit's main source file. However, STABS
entries can only hold one address, so STABS indicates the compilation
unit's ending address with an N_SO entry whose name is empty.
Currently, the dumper's data structures simply create SourceFileInfo
structures with empty names for these end-of-unit N_SO entries. We
want to remove STABS-specific characteristics from these structures so
that we can replace them with an input-format-independent structure.
This moves end-of-compilation-unit addresses out of the symbol table
structure, and into their own list of boundary addresses.

Use a list of pointers to SourceFileInfo structures, not a list of the
structures themselves. This is preparation for a subsequent patch
which makes the data structures less STABS-specific.
This patch introduces a memory leak. If an included file is
referenced only by line entries for functions that LoadFuncSymbols
elected to omit from the func_info list, then its SourceFileInfo
structure is leaked when we destroy the name_to_file map. This leak
is fixed in a subsequent patch by letting the map of files by name own
the file objects.
