what architecture name is shown in a symbol file's MODULE line, but the Mac
crash_report tool's on_demand_symbol_supplier does. The new Mac dumper
inadvertently used i386. Correct that to make it x86. Temporarily make the
on_demand_symbol_supplier accept symbol files whose architecture is i386.
Also add x86_64 to the set of architectures that the on_demand_symbol_supplier
considers valid.

This patch rewrites the Mac symbol dumper to use the same set of classes
the Linux dumper does for reading debugging information from various
sources, consolidating them into a single table, and writing that out as a
Breakpad symbol file.
In the process, it also adds support for dumping DWARF call frame
information and .eh_frame exception-handling information as Breakpad 'STACK
CFI' records. This allows the Breakpad processor to generate stack traces
from code compiled with -fomit-frame-pointer.
The patch also replaces the DumpSymbols Objective C++ class with
google_breakpad::DumpSymbols, a plain C++ class. The code still uses some
Objective C++ to use the Foundation facilities for dealing with file names
in a file-system-independent fashion, and for examining the contents of
.dSYM bundles.
Since the code has been entirely rewritten, I have changed the author
lines.

This patch adds files defining new classes in the google_breakpad::Mach_O
namespace for parsing fat binaries and Mach-O files. These are used in the
new dumper to handle STABS debugging information, DWARF call frame
information, and .eh_frame exception handling stack walking information.
These new classes are independent of endianness and word size, and
therefore can be used on binaries of all the relevant architectures: x86,
x86_64, ppc, and ARM.
The patch adds a complete set of unit tests for the new classes.

Breakpad's Macintosh symbol dumper uses deprecated functions for
dealing with mixed-endianness code. This patch provides an overloaded
function, ByteSwap, that automatically chooses the OSSwap* functions
from <libkern/OSByteOrder.h> appropriate for its argument's
size.
This patch does *not* address warnings in src/common/mac/dump_syms.mm,
because that code is about to be replaced entirely; there's no reason to
bother reviewing a big, detailed patch against it.

Move the DWARF parser, and the functioninfo.cc DWARF consumer, from
src/common/mac/dwarf to src/commmon/dwarf, so that it can be shared
between the Mac and Linux dumpers.
Fix up #include directives, multiple inclusion protection macros, and
Xcode build files.

Modern GNU compilers warn about the #inclusion of <ext/hash_map>; that
container is deprecated, and code should use <tr1/unordered_map>
instead. However, to stay within the boundaries of C++ '98, it's
probably fine just to use plain old std::map.
Breakpad uses hash_map in three cases:
o The DWARF reader's SectionMap type maps object file section names to
data. This map is consulted once per section kind per DWARF
compilation unit; it is not performance-critical.
o The Mac dump_syms tool uses it to map machine architectures to
section maps in Universal binaries. It's hard to imagine there
ever being more than two entries in such a map.
o The processor's BasicSourceLineResolver uses a hash_map to map file
numbers to file names. This is the map that will probably have the
most entries, but it's only accessed once per frame, after we've
found the frame's line entry.

This upload fixes five issues:
1) Preston's email was hardcoded in the xib :-(
2) Changed from xib to NIB to facilitate Tiger building
3) Changed the logs location to be user specifiable by BreakpadMinidumpLocation
key, or ~/Library/Breakpad/<BREAKPAD_PRODUCT> by default
4) Fixed GTM Defines problem in order to build on Tiger
5) Also set CFBundleIcon in the sender program correctly, and updated plist, and
renamed ReporterIcons to crash_report_sendER.ICNS. However the rietveld upload
script doesn't appear to pick up renamed files correctly, so that file doesn't
show up in the patch upload.
Also various comments were updated for accuracy.

The method of calculating a binary ID using the LC_ID command isn't compatible with non-default build processes, most Mac consumers
use LC_UUID anyway but for those that don't, MD5 is a better choice
