Some systems provide prebuilt copies of gmock/gtest (such as Chromium
OS). Add a configure flag so they can take advantage of that. This
allows for a smaller checkout as they don't need to include the full
testing/ tree.

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 CL https://codereview.chromium.org/1563223004/
This reverts commit 7cc0d8562bf8b20b88cc941ba72593cb7230ecf6.
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.

Patch from Olivier Robin <olivierrobin@chromium.org>.
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>&)'

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.

Older versions of MSVC don't have a snprintf functions. Some files
were already working around that, but not all of them. Instead of
copying the logic into every file, I centralize it into a new
stdio.h wrapper file and make other files include that.

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.

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.

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.

There is an issue in StackwalkerAMD64::GetCallerByFramePointerRecovery.
Occasionally it produces invalid frames (instruction pointer == 0) which
prevents the AMD64 stack walker from proceeding to do stack scanning and
instead leads to premature termination of the stack walking process.

The Windows client gyp files were missing proc_maps_linux.cc for the
unittest build. Adding that revealed some build errors due to it
unconditionally including <inttypes.h>. Removing the workarounds in
breakpad_types.h (and a few other places) made that build, which means
that Visual C++ 2013 is now our minimum supported version of MSVC.
Additionally I tried building with VC++ 2015 and fixed a few warnings
(which were failing the build because we have /WX enabled) to ensure
that that builds as well.

Chrome started hitting some crashes in v8 jitted code which happens to be
non ABI compliant and debuggers (including WinDBG) are unable to produce
meaningful stack traces.
The Breakpad stack walker has some builtin heuristics to deal with such cases.
More specifically, when unable to find a good parent frame, it scans the raw
stack to find a suitable parent frame. The max scan size was set at 30
pointers which was (apparently) not enough to recover in this case.
I'm increasing it to 40 pointers. I confirmed that at 34 pointers it was able
to recover however I'm setting it to 40 in order to it some slack.
I needed to update two unittests which were expecting the previous scan limit.

Patch from Pavel Labath <labath@google.com>.
Although strictly the GPU fingerprint is defined by the build fingerprint,
there is not currently a straightforward mapping from build fingerprint
to useful GPU / GL driver information.
In order to aid debugging of WebView crashes that occur in GL drivers,
and to better understand the range of drivers and versions for feature
blacklisting purposes, it is useful to have GPU fingerprints in breakpad
microdumps.
