df280bb631 Parse additional line introduced in the microdump format and containing the GPU infromation in the following format:
G GL_VERSION|GL_VENDOR|GL_RENDERER.

The GPU version, vendor and renderer are extracted during microdump parsing and populated in the appropriate fields in the SystemInfo struct.

This is to match the changes introduced in crrev.com/1343713002 and crrev.com/1334473003

4912669df1 Change MDCVInfoELF into something usable.
This patch changes MDCVInfoELF (which is currently unused, apparently
a vestigal bit of code landed as part of Solaris support) into a supported
CodeView format that simply contains a build id as raw bytes.

Modern ELF toolchains support build ids nicely:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Developer_Guide/compiling-build-id.html

It would be useful to have the original build ids of loaded modules in
Linux minidumps, since tools like Fedora's darkserver allow querying by build
id and the current Breakpad code truncates the build id to the size of a GUID,
which loses information:
https://darkserver.fedoraproject.org/

A follow-up patch will change the Linux minidump generation code to produce
MDCVInfoELF in minidumps instead of MDCVInfoPDB70. This patch should be landed
first to ensure that crash processors are able to handle this format before
dumps are generated containing it.

The full build id is exposed as the return value of Minidump::code_identifier(),
which currently just returns "id" for modules in Linux dumps. For
backwards-compatibility, Minidump::debug_identifier() continues to treat
the build id as a GUID, so debug identifiers for existing modules will not
change.

442b45266d Improvements to GYP build
This updates the GYP build for the processor component (on windows).
- adds/removes references to files which were added or removed from the
  repository
- includes build/common.gypi in the gyp files: needed to correctly
  detect the OS (I think, the generated MSVC solutions were broken
  without it)
- conditionally compiles code platform-specific code for the given
  platform

After this minidump processor nearly compiles with VS2013: the generated
project is correct, but some files still have compilation errors.

Disclaimer: I have not tested the GYP changes on non-windows platform,
as there does not seem to be anyone using it there.

3f736ce086 only build dump_syms_mac for x86 hosts
The dump_syms_mac tool only works for the system it is being built for
(it doesn't support running on ELFs for a diff target), and it builds
only for x86 currently.

If you look at the mac header:
	src/third_party/mac_headers/mach/machine/vm_types.h
it will #error for non x86/arm systems, and the arm header is not in
our source tree.

Tweak the build so it's only compiled when targetting x86 systems.

83523e066b test: stop building tons of copies of gtest/gmock objects
The current makefile ends up building ~17 copies of the gtest/gmock
objects -- every test that refers to the cc files directly will have
its own copy.  This is because the build doesn't know if CFLAGS and
such have changed between each target (and in some cases, they are).

Create a new libtesting.a target to hold a single copy of these files
and update all of the unittests to link that in.  This speeds up the
build a bit especially when you aren't using ccache.

This does mean we can no longer build gtest/gmock with unique flags,
but we haven't wanted that so far, so clearly no one wants that.

This reverts commit 7cc0d8562b.

CL 1563223004 introduces two bugs on iOS.
- Encoding the minidump name with extra percent causing crash server to fail
  processing the file.
- Using a released pointer causing random crashes on upload. The
  data, resp, err pointers returned in the NSURLSession completion
  handler is released at the end of the block. When used later (to get
  the crash ID), it causes a crash.

8baa236daa exploitability_unittest: fix warnings
The std::getline function always returns its first arg (which is an
iostream object) and cannot return anything else.  Thus, testing its
value is pointless, and even leads to build errors w/at least gcc-5
due to gtest ASSERT_TRUE funcs only taking bool types:

.../exploitability_unittest.cc: In member function 'virtual void {anonymous}::ExploitabilityLinuxUtilsTest_DisassembleBytesTest_Test::TestBody()':
.../exploitability_unittest.cc:200:136: error: no matching function for call to 'testing::AssertionResult::AssertionResult(std::basic_istream<char>&)'
In file included from .../breakpad_googletest_includes.h:33:0,
                 from .../exploitability_unittest.cc:35:
.../gtest.h:262:12: note: candidate: testing::AssertionResult::AssertionResult(bool)

Since we know this never fails, simply drop the ASSERT_TRUE usage.
The next line already checks the content of the buffer we read.

Further on in the file, we hit some signed warnings:
In file included from .../breakpad_googletest_includes.h:33:0,
                 from .../exploitability_unittest.cc:35:
.../gtest.h: In instantiation of 'testing::AssertionResult testing::internal::CmpHelperEQ(const char*, const char*, const T1&, const T2&) [with T1 = long unsigned int; T2 = int]':

.../gtest.h:1448:16: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
   if (expected == actual) {

This is because we compare the register value (a uint64_t) directly to
an integer constant, and those are signed by default.  Stick a U suffix
on them to fix things up.

`ar` all the time.  When cross-compiling, this can often be the wrong
one to use.

2d1b97a1ff Don't include libdisasm.a in libbreakpad.a
libbreakpad.a pointlessly contains libdisasm.a

This looks like a left-over from when libtool was used

Since this has no useful effect (as the linker doesn't recursively search
archive members which aren't objects), anything which requires the objects in
libdisasm.a must already be linking with it, so simply remove it.

ee69060bfd Install headers under client/linux/dump_writer_common
Automake did not install headers under c/l/dwc, which caused
compile errors when building against an installed breakpad, since
other headers (e.g. client/linux/handler/exception_handler.h)
depended on it. This commit adds these headers to the list of
automake installed files.

aa5ff205cb Android: Workaround for ftruncate() issues.
This works around a bug in M that prevents Breakpad from using
ftruncate() in the renderer process.

To do this, skip the calls to ftruncate() when allocating bigger
minidump files and strictly depends on write() to append to the end.

It might be less efficient but this is probably less of an issue on
SD cards. It is much better than not getting crash reports.
