We're working on building our Firefox Mac builds as a Linux cross-compile
(https://bugzilla.mozilla.org/show_bug.cgi?id=921040) and we need symbol
dumping to work. This change ports the Mac dump_syms tool to build and work
on Linux. I've tested it and it produces identical output to running the
tool on Mac.
The bulk of the work here was converting src/common/mac/dump_syms.mm and
src/tools/mac/dump_syms/dump_syms_tool.mm from ObjC++ to C++ and removing
their use of Foundation classes in favor of standard C/C++.
This won't compile out-of-the-box on Linux, it requires some Mac system
headers that are not included in this patch. I have those tentatively in
a separate patch to land in Gecko
(http://hg.mozilla.org/users/tmielczarek_mozilla.com/mc/rev/5fb8da23c83c),
but I wasn't sure if you'd be interested in having them in the Breakpad tree.
We could almost certainly pare down the set of headers included there, I
didn't spend too much time trying to minimize them (we primarily just need
the Mach-O structs and a few associated bits).
I just realized that this patch is missing updating the XCode project files
(ugh). I'll fix that up in a bit.

This libcrypto dependency sucks. Linking against OpenSSL is sort of broken in
certain Mac OS X SDKs. libcrypto was only being used to provide an MD5
implementation. Breakpad already has its own MD5 implementation, so just use
that instead.
To be perfectly honest, on modern systems, nothing should be making MD5
hashes of modules anyway, because everything has an embedded LC_UUID.
The project file changes just remove libcrypto and add md5.c as needed.
A bonus (and untested) fix for on_demand_symbol_supplier.mm is included to
account for changes in r794.
