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...

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.
