bazel build --define=absl=1 ...

A dependency on RE2 is now required when building GoogleTest with Abseil.
Using RE2 will provide a consistent cross-platform regex experience.

Users will need to add the com_googlesource_code_re2, bazel_skylib,
and platforms repository to their WORKSPACE files. See our WORKSPACE
file in the root directory of this project for an example of how to
add the dependencies.

Please note that the com_googlesource_code_re2 dependency must use a
commit from the `abseil` branch of the project:
https://github.com/google/re2/tree/abseil

When built with `--define=absl=1` under Bazel, GoogleTest
flags use ABSL_FLAG instead of GoogleTest's own implementation.

There are some minor behavior differences in this mode.

The most notable difference is that unrecognized flags result
in a flag parsing error, and are not returned to the user though
a modified argc/argv, unless they appear after the positional
argument delimiter ("--").

For example, to pass a non-Abseil flag, you would have to do
./mytest --gtest_color=false -- --myflag=myvalue

The documentation at https://abseil.io/docs/cpp/guides/flags
may be helpful in understanding the behavior.

There are some other minor differences. For example,
passing --help results in the program returning 1 instead of 0.

According to the 2nd point on [1], -lregex is required on QNX.

On QNX, pthread is part of libc [1]. There's no separate pthread library
to link.

Remove the dependency on Objective C++ in iOS builds.

252ce9c5 introduced the use of
NSTemporaryDirectory() on iOS, which requires Core Foundation, and
Objective C++.

This CL replaces NSTemporaryDirectory() with an equivalent solution
(according to Apple's documentation at [1]) available to C/C++ code.
Avoiding Objective C++ and Core Foundation makes it easier to integrate
googletest in projects that can't use the supplied Bazel build files.

Print std::u8string, std::u16string, and std::u32string as string literals

Previously, these types were printed as "{ U+123, U+456, U+789 }". However,
printed output in that form is difficult to compare against any literals that
might be defined in code. Instead, just treat these types like std::string
and std::wstring, escaping non-ASCII characters with a hexadecimal escape
sequence.

The tests have also been updated to cover the new functionality: as a bonus,
the tests now also pass with the MSVC toolchain.

Internally, the code has been reorganized to primarily operate in terms of
char32_t, under the assumption that char32_t will always be at least as big
as wchar_t. While that assumption is currently true, perhaps it won't be in
the future...

This makes it easier to include the license in redistributions, as required by the license.

Fixes googletest for upcoming `--incompatible_load_cc_rules_from_bzl` (https://github.com/bazelbuild/bazel/issues/8743) and `--incompatible_load_python_rules_from_bzl` (https://github.com/bazelbuild/bazel/issues/9006).

This change was automatically generated with `buildifier -lint=fix -warnings=all $(find . -name "BUILD" -o -name "BUILD.bazel" -o -name "*.bzl")`.

While the google test library is being built as a shared library using Bazel,
so that there is a rule like

cc_test(
     name = "iterator_traits_test",
     linkstatic = 0,
     deps = ["@gtest//:gtest_main"],
     ...
)

in a BUILD file, the following error appears on Windows:

INFO: Found 1 test target...
ERROR: C:/../external/gtest/BUILD.bazel:55:1: output 'external/gtest/gtest.if.lib' was not created
ERROR: C:/../external/gtest/BUILD.bazel:55:1: not all outputs were created or valid
Target //test:iterator_traits_test failed to build

The reason is a missing "win_def_file" attribute of the "gtest" and
"gtest_main" rules in the BUILD.bazel inside the google test library
package.

The "windows_export_all_symbols" feature is added to the rules, this
feature forces Bazel to export all symbols from the google test library
to linker. I believe exporting all symbols from a testing library makes
no problem for the application from a point of view on encapsulation.

Improve Bazel build files.

New target gtest_prod allows access to the FRIEND_TEST macro without depending on the entirety of GTest in production executables. Additionally, duplicate config_setting rules were removed and formatting was adjusted.

This change adds the ability to generate stacktraces in Google Test on
both failures of assertions/expectations and on crashes. The
stacktrace support is conditionally available only when using Abseil
with Google Test.

To use this support, run the test under Bazel with a command like this:

bazel test --define absl=1 --test_env=GTEST_INSTALL_FAILURE_SIGNAL_HANDLER=1 //path/to/your:test

The "--define absl=1" part enables stacktraces on assertion/expectation
failures.

The "--test_env=GTEST_INSTALL_FAILURE_SIGNAL_HANDLER=1" part enables
the signal handler that logs a stacktrace in the event of a crash
(this also requires the "--define absl=1" part). This is not the
default since it may interfere with existing tests.
