Remove obsolete argument limit documentation.
Combine uses variadic templates now, so there is no inherent limit on the number of arguments.

Print unique_ptr/shared_ptr recursively.
Given that they are smart pointers, it is unlikely that the inner object is
invalid.

Launder buffer before reference
In GCC, directly casting the Buffer reference to another type results in
strict-aliasing violation errors. This launders the reference using an
intermediate pointer prior to creating the new reference.

Change Matcher<T> to allow binding an implementation by value directly:
- Drop the requirement of MatcherInterface. Doing manual type erasure avoid
extra layers in many cases.
- Avoid the adaptor for `MatcherInterface<T>` and `MatcherInterface<const T&>` mismatch.
- Use a small object optimization when possible. This makes things like
`_` and `Eq(1)` really cheap and do not require memory allocations.
- Migrate some matchers to the new model to speed them up and to test the new framework. More matchers to come in future changes.

Affects macros {ASSERT|EXPECT}_{EQ|NE|LE|LT|GE|GT}.
According to removed comments, these overloads were supposed to reduce
code bloat and allow anonymous enums on GCC 4.
However, the way it works on GCC 4 and the latest GCC (10.2 by now) is
that having:
template <typename T1, typename T2>
void foo(T1, T2);
using BiggestInt = long long;
void foo(BiggestInt, BiggestInt);
the template version takes precedence for almost every combination of
integral types except for two long long integers - i.e. implicit
promotion to long long is a worse match than generating a specific
template function.
Tested on GCC 4.8.1 (as GoogleTest requires C++11 and this was
the first C++11 feature-complete release of GCC),
GCC 4.8.5 (last of 4.8.x series) and the latest GCC (10.2.0).
Include TargetConditionals.h before checking TARGET_OS_IPHONE
New versions of Clang require that you include TargetConditionals.h before checking the TARGET_OS_* macros. Include it where appropriate to keep the compiler happy.

Use a tagged constructor for FlatTuple instead.
Some versions of MSVC are getting confused with that constructor and generating invalid code.

Improve lookup of operator<< for user types
Without this fix, trying to use this class with googletest
struct Foo {};
template <typename OutputStream>
OutputStream& operator<<(OutputStream& os, const Foo&) {
os << "TemplatedStreamableInFoo";
return os;
}
results in an ambiguity error between the class' operator<< and the
operator<< in gtest-printers.h removed in this CL.
This fix also enables implicit conversions to happen, so that e.g.
we will find the base class operator<< if a subclass has no
operator<< of its own.

Add millisecond precision to start timestamp in XML/JSON output
- Previous timestamp had format YYYY-MM-DDThh:mm:ss, now YYYY-MM-DDThh:mm:ss.sss
- This conforms to the ISO 8601 standard

Detection of string_view type (whether it's std or Abseil)
is done in googletest/include/gtest/internal/gtest-port.h
with GTEST_INTERNAL_HAS_STRING_VIEW.
Make visible ParseInt32 in case users have separate gmock/gtest libraries and hidden-by-default symbols.
This function is still considered an internal implementation detail and is subject to change without notice. It is still unsafe/unsupported to link together libraries built at different commits.

Adds support for printing the types char8_t, char16_t, and char32_t
This changes prints these types as Unicode code points. It is possible
that there is a better way of printing these types, but that change is
more complex, and the format in which Googletest prints these types is
subject to change if someone implements a better way of printing them.
This fixes the C++20 build, which removed support for printing these types.

Fixed#2823 - Make it so that a semicolon appearing after an invocation of GTEST_SUPPRESS_UNREACHABLE_CODE_WARNING_BELOW_ does not trigger a redundant semicolon warning.
This works by introducing an else block with a statement that intentionally does not end with a semicolon, forcing users to place the semicolon after the expansion. The approach here is preferred as opposed to removing semicolons that appear after each invocation because complete statements that do not have a visible semicolon or braces confuse users and code formatters, since the macro invocation looks superficially like an expression.
