This hides the need to provide mutable C strings, and unifies
existing basename calls and variations in a single location.

Added new files elf_reader and corrected the references to dump_syms. Also some corrections to be able to build using a newer Xcode and SDK version (tested with Xcode 7.3, SDK 10.11).

Previously, if the input file was missing, the symupload tool on Mac
would happily process, try to parse it (calling a method on nil) and
fail when trying to create the payload to send to the server as one
of the method raised a NSInvalidArgumentException when receiving a
nil value.
Change to code to instead check the file for existence which makes it
easier to understand what is happening when part of the build system
is misconfigured and invoke symupload without first creating the symbol
file.

It is often helpful to check if a particular symbol file dumped by
dump_syms actually matches a version of a binary file we have. The
symbol output contains an ID which can be used to see if it matches
the binary file. Unfortunately, this ID is internally calculated
and not a standard hash of the binary file. Being able to output the
header information only will allow users to determine whether their
symbol file is up to date or not.

Patch from David Yen <dyen@chromium.org>.
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 adds a new |-g <dSYM path>| flag to dump_syms, to specify the dSYM path for
the target Mach-O argument. The UUIDs and architectures of the two paths must
match in order to dump symbols for this "split module."
This reason for this is that for x86_64 binaries on OS X, the CFI data is stored
in the __TEXT,__eh_frame segment of the Mach-O file, and the data is not copied
into the dSYM by dsymutil. Therefore, just dumping the dSYM doesn't yield CFI
data for x86_64 files, and both the dSYM and the Mach-O file must be dumped in
order to produce a complete Breakpad symbol file. For i386 binaries, the CFI data
is stored in the __DWARF,__debug_frame segment, which is part of the dSYM, so
this isn't necessary.

This GYP-ifies the src/processor and src/common directories on those platforms
as well. The Makefile build uses much more granular unittest executables, so
the new processor_unittests does not yet link because of multiple main() symbols,
but this will be fixed later.

More specifically:
- Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report.
- Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen.
- In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates.
- Added and updated unittests.
Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this:

NXGetArchInfoXXX depends on the OS knowledge of architecture. This CL adds a
custom implementation of those methods to be able to handle newer CPU before
they are handled by the OS. It also add handling for armv7s architecture.

symupload printed -[NSData length], an NSUInteger, using %lu. %lu is proper
to print a "long" as unsigned, but NSUInteger is a typedef for "unsigned int"
when building for 32-bit. This would not have caused any problems, because in
the 32-bit model, both int and long are 32 bits wide. In the 64-bit model,
long is 64 bits wide, but NSUInteger is defiend as "unsigned long", so there
wouldn't have even been a warning in that case.
This addresses the following warning:
symupload.m:137:30:{137:28-137:31}{137:46-137:59}: warning: conversion specifies type 'unsigned long' but the argument has type 'NSUInteger' (aka 'unsigned int') [-Wformat]

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.

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 adds all the appropriate symbol dumper unit tests to the Mac
