Cast some values as their unsigned equivalents or `size_t` to match the
parameter type used for the template object under test. Also, provide
UInt32 equivalent delegate methods for some callers (with
int-equivalents for backwards compatibility).
This closes#2146.

Add HWASan annotations.
These mirror existing ASan annotations.
HWASan uses memory (address) tagging to detect memory errors:
https://clang.llvm.org/docs/HardwareAssistedAddressSanitizerDesign.html
It inserts a random tag in the MSB of heap and stack allocation addresses. This tag dominates pointer comparison in StackGrowsDown(), making the result non-deterministic, and entirely unrelated to the actual stack growth direction. The function attribute disables this behavior.
The annotations in gtest-printers are there because the printers are used to basically dump memory. The sanitizers may have ideas why this memory should not be accessed, and that is counter productive. In particular, the test may access only part of an array, but in case of a test failure gtest will dump the entire array which may contain uninitialized bytes - that's what SANITIZE_MEMORY annotation is for. There are similar reasons for ADDRESS and THREAD annotations. HWADDRESS in its current implementation can not cause issues there, I believe, but it falls under the same umbrella of tools whose checking should not apply to test printers because it is not the code under test.

Remove support for "global" ::string and ::wstring types.
This support existed for legacy codebases that existed from before namespaces
where a thing. It is no longer necessary.

Fix emission of -Wzero-as-null-pointer-constant when comparing integers.
The following code fails to compile:
#pragma clang diagnostic error "-Wzero-as-null-pointer-constant"
void foo() {
EXPECT_EQ(0, 0);
}
This happens because gtest checks the first argument to EXPECT_EQ and
ASSERT_EQ is a null pointer constant. The magic it does to do this causes the
warning to be emitted.
This patch removes that check. It replaces the explicit check with a Compare
overload that can only be selected when 0 or nullptr is passed on the LHS
with a pointer on the right.
This patch does not suppress -Wzero-as-null-pointer-constant when users
are actually using it as NULL.

Let embedders customize GTEST_INTERNAL_DEPRECATED().
GTEST_INTERNAL_DEPRECATED is currently used to nudge googletest users to migrate off old TEST_CASE macros to the new TEST_SUITE macros. This move is non-trivial for Chromium (see https://crbug.com/925652), and might be difficult for other big projects with many dependencies.
This CL facilitates moving off of deprecated APIs by making it possible for an embedder to define GTEST_INTERNAL_DEPRECATED() in gtest/internal/custom/gtest-port.h. Example usage:
1) #define GTEST_INTERNAL_DEPRECATED() to nothing, to disable deprecation warnings while migrating off googletest's deprecated APIs. This can be preferable to having to disable all deprecation warnings (-Wno-error=deprecated or -Wno-deprecated-declarations).
2) #define GTEST_INTERNAL_DEPRECATED() for an unsupported compiler.

Fix matcher comparisons for std::reference_wrapper.
The googletest docs indicate that std::reference_wrapper should be used to for
objects that should not be copied by the matcher (in fact, the ByRef() function
is basically the same as a call to std::cref).
However, for many types (such as std::string), the overloaded operator== will
not resolve correctly. Specifically, this is problematic if operator== depends
on template argument deduction, where the same type is named on LHS and RHS.
Because template argument deduction happens before any implict conversions for
purposes of overload resolution, attempting to compare T with
std::reference_wrapper<T> simply looks like a comparison of unlike types.
For exapmle, std::reference_wrapper<std::string> is implicitly convertible to
'const std::string&', which would be able to choose an overload specialization
of operator==. However, the implicit conversion can only happen after template
argument deduction for operator==, so a specialization that would other be an
applicable overload is never considered.
Note also that this change only affects matchers. There are good reasons that
matchers may need to transparently hold a std::reference_wrapper. Other
comparisons (like EXPECT_EQ, et. al.) don't need to capture a reference: they
don't need to defer evaluation (as in googlemock), and they don't need to avoid
copies (as the call chain of matchers does).

Fix warning about deprecation of implicit operations such as copy constructors or assignment operators.
Specifically:
MatcherBase's default copy constructor, assignment operator, move operator, and move assignment operator are now declared explicitly rather than depending on the compiler implicit generation (which is disallowed/warned against due to MatcherBase's declaration of the destructor).

Improved flexibility by removing the Arduino entry points in favor of manual calls to setup/loop that the user can call from their entry point. This is the more common use case for Arudino.
Also added the gtest/gmock_main files to the PlatformIO ignore list since we are not supporting that feature.

Now that googletest has moved to C++11, it should no longer
use NULL or 0 for the null pointer. This patch converts all
such usages to nullptr using clang-tidy.
This prevents LLVM from issuing -Wzero-as-null-pointer-constant
warnings.

Commit 6a26e47cfc changed the formatting
of INSTANTIATE_TEST_CASE_P() in the generated header file only.
This commit reverts to the formatting produced by running "pump
gtest-param-test.h.pump", which seems to be more consistent with the
rest of the file.

As required by googletest documentation, the names should not contain an underscore.

Add the possibility of specifying the name in type parameterized tests.
Similar to how the last parameter of INSTANTIATE_TEST_CASE_P allows to override the name for (non-type) parametrized tests, this adds the possibility of adding a parameter to INSTANTIATE_TYPED_TEST_CASE_P. The argument has to be a class, which contains a static templated function GetName<T>(int), returning the name for type T.

Fix Theta(N^2) memory usage of EXPECT_EQ(string) when the strings don't match.
The underlying CalculateOptimalEdits() implementation used a simple
dynamic-programming approach that always used N^2 memory and time. This meant
that tests for equality of large strings were ticking time bombs: They'd work
fine as long as the test passed, but as soon as the strings differed the test
would OOM, which is very hard to debug.
I switched it out for a Dijkstra search, which is still worst-case O(N^2), but
in the usual case of mostly-matching strings, it is much closer to linear.

Because in `std::tr1::tuple_element` the first template parameter should be of type int (https://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-html-USERS-4.4/a00547.html), but the code inserts a size_t, the first template parameter should be casted to int before, to get rid of the following errors:
googletest-src/googletest/include/gtest/gtest-printers.h:957:60: error: conversion from ‘long unsigned int’ to ‘int’ may change value [-Werror=conversion]
struct tuple_element : ::std::tr1::tuple_element<I, Tuple> {};

GTEST_TEST_FILTER_ENV_VAR_ was used to specify an environment variable to obtain
the default test filter from. By default it was unset which broke
"--test_filter" for bazel. This CL eliminates GTEST_TEST_FILTER_ENV_VAR_ and
explicitly obtains the default test filter from the environment variable
TESTBRIDGE_TEST_ONLY if it exists.
This canonicalizes demangled names by omitting a nested inline namespace within namespace std if the name of the nested namespace begins with a double underscore. This improves compatibility with libc++.
This allows doing things like TEST_P(TestFixture, MAYBE(TestName))
for nicer conditional test disabling.

Google Test has recently (02/09/2018) switched the default death test
style from "fast" to "threadsafe" in
ec7faa943d
Threadsafe death tests have been used internally for a while, and are
proven to be a better default.
However, adopting this better default can be challenging for large
projects with a significant investment in custom infrastructure built on
top of Google Test. The same custom infrastructure can make it difficult
for large projects to switch back to the old default by passing in
--gtest_death_test_style=fast.
For the reasons above, the default switch is considered too disruptive,
and this CL reverts it. This CL also introduces the
GTEST_DEFAULT_DEATH_TEST_STYLE preprocesor macro, which replaces the
hard-coded default. The macro can be defined in
gtest/internal/custom/gtest-port.h by projects that are ready to migrate
to thread-safe death tests.
_HAS_EXCEPTIONS is specific to the MSVC STL and defining it to 0 causes
problems with libc++, so libc++ users may leave it undefined. This can
cause GTEST_HAS_EXCEPTIONS to be defined incorrectly if the user has
disabled exceptions via the compiler, which can lead to build errors.
_CPPUNWIND is a builtin macro provided by the compiler so it should
work with both STLs.
