Make GTestColor and ColoredPrintF available as internal APIs from gtest.h.  This is for use in abseil exception safety testing.

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.

Fix Clang warning:
| warning: definition of implicit copy constructor for 'ValueArray2<bool, bool>'
| is deprecated because it has a user-declared copy assignment operator [-Wdeprecated]

Add declarations for install_failure_signal_handler and flagfile.

Fix Clang warnings:
| warning: no previous extern declaration for non-static variable
| 'FLAGS_gtest_install_failure_signal_handler' [-Wmissing-variable-declarations]
| warning: no previous extern declaration for non-static variable
| 'FLAGS_gtest_flagfile' | [-Wmissing-variable-declarations]

Fix -Wmissing-variable-declarations warnings from Clang.

Commit 6a26e47c 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.

Fix the typed test names in the tests for customized typed test parameters.

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.
