- Checking symbol status would fail for files whose names contained spaces, because the file name was being put in the URL unescaped.

A .dSYM may validly contain a __DWARF segment without any __debug_info
section. This can occur for Chromium Framework in a component build of
Chromium, because in that case, all of the code is in other libraries
that Chromium Framework depends on.
This was previously tested by an assertion, but the assertion did not
trigger in NDEBUG (release) builds. In NDEBUG builds, this condition
would lead to an out-of-bounds read, detected by AddressSanitizer.
Instead of an assertion, the check is now always done at runtime.
Instead of being fatal, it's now just a warning, because it's been
established that __DWARF without __debug_info can occur.
(In the Chromium case, it remains pointless to run dump_syms via the
"chrome_dump_syms" target on a component build, as it'll only attempt to
symbolize Chromium Framework, and not any of the libraries that Chromium
Framework depends on that actually contain the code.)

Even 64-bit Mach-O (MH_MAGIC_64 = 0xfeedfacf) is not a fully 64-bit file
format. File offsets in sections are stored in 32-bit fields, with
Mach-O writers typically truncating offsets too large to fit to just
their low 32 bits. When a section begins at a file offset >= 4GB,
dump_syms would produce an error such as:
Google Chrome Framework.dSYM/Contents/Resources/DWARF/Google Chrome Framework: the section '__apple_names' in segment '__DWARF' claims its contents lie outside the segment's contents
As a workaround, this implements the strategy I first described in
https://crbug.com/940823#c22.
Segment file offsets are stored in 64-bit fields. Because segments
contain sections and must load contiguously, it’s possible to infer a
section’s actual offset by computing its load address relative to its
containing segment’s load address, and treating this as an offset into
the containing segment’s file offset. For safety, this is only done for
64-bit segments (LC_SEGMENT_64) where the 32-bit section offset stored
in the Mach-O file is equal to the low (truncated) 32 bits of the
section offset recomputed per the above strategy.
Beware that this does not provide full “large file” support for 64-bit
Mach-O files. There are other file offsets within Mach-O files aside
from section file offsets that are stored in 32-bit fields even in the
64-bit format, including offsets to symbol table data (LC_SYMTAB and
LC_DYSYMTAB). No attempt is made to recover correct file offsets for
such data because, at present, such data is always stored by dsymutil
near the beginning of .dSYM files, within the first 4GB. If it becomes
necessary to address these other offsets, it should be possible to
recover these offsets by reference to the __LINKEDIT segment that
normally contains them, provided that __LINKEDIT doesn’t span more than
4GB, according to the strategy discussed at the bottom of
https://crbug.com/940823#c22.
Although this is sufficient to allow dump_syms to interpret Chromium
.dSYM files that exceed 4GB, be warned that these Mach-O files are still
technically malformed, and most other tools that consume Mach-O files
will continue to have difficulties interpreting these large files.
As further warning, note that should any individual DWARF section exceed
4GB, internal section offsets will be truncated irrecoverably, unless
and until the toolchain implements support for DWARF64.
https://bugs.llvm.org/show_bug.cgi?id=14969
With this change, dump_syms is able to correctly recover file offsets
from and continue processing a .dSYM file with length 4530593528
(4321MB), whose largest section (__DWARF,__debug_info = .debug_info) has
size 0x8d64c0b8 (2262MB), and which contains four sections (starting
with __DWARF,__apple_names) beginning at file offsets >= 4GB.

This enables the DWARF reader to properly parse DW_AT_ranges attributes
in compilation units and functions. Code covered by a function is now
represented by a vector of ranges instead of a single contiguous range
and DW_AT_ranges entries are used to populate it. All the code and tests
that assumed functions to be contiguous entities has been updated to
reflect the change. DW_AT_ranges attributes found in compilation units
are parsed but no data is generated for them as it is not currently needed.

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 Pavel Labath <labath@google.com>.
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 CL adds three features that will allow the client to upload the report
file.
Three main modifications are made :
- Allow upload url to have a file:// scheme, and write the HTTP request to file
in that case
- Split the request in two parts in case of a file:// scheme, the request
time and the response time. A new API [handleNetworkResponse] is added.
- Give the opportunity to the client to get the configuration NSDictionary
to be able to recreate the breakpad context at response time.
