Previously this excluded callables that return non-moveable types. This is the
same as the
[libc++ std::is_invocable_r bug](https://github.com/llvm/llvm-project/issues/55346)
fixed by
[this commit](https://github.com/llvm/llvm-project/commit/c3a24882903d): it's
wrong to use std::is_convertible for checking the return type, since (despite
its name) that doesn't check the standard-defined notion of "implicitly
convertible". Instead we must base the check on whether the source type can be
used as an argument to a function that accepts the destination type.

`Return(x)` can now be used directly with `WillOnce` (the only place it makes
sense in the type system), without using `ByMove`.

It doesn't make semantic sense for the conversion to modify the input, and the
fact that it's allowed to do so appears to have just been a historical accident.

Better document requirements, API decisions, and historical accidents. Make an
implicit conversion easier and in a more appropriate place, and ease the burden
of some assertions in the conversion operator. Stop using the legacy
ActionInterface style for defining the action.

So that it can be referenced in conversion operators for actions that need to
know the concrete return type.

Commit a070cbd91c added an implicit cast to this path but didn't leave a very
clear explanation for why it was desirable, a clear example, or even test
coverage. Add a better comment and a test that fails when the implicit cast is
removed.

This is necessary for generic support of these actions, since `DoAll` is a
frequently-used action wrapper.

This provides a type-safe way for an action to express that it wants to be
called only once, or to capture move-only objects. It is a generalization of
the type system-evading hack in ByMove, with the improvement that it works for
_any_ action (including user-defined ones), and correctly expresses that the
action can only be used with WillOnce. I'll make existing actions benefit in a
future commit.

A few tests are examining code locations and looking af the resulting line
numbers to verify that GoogleTest shows those to users correctly. Some of those
locations change when clang-format is run. For those locations, I've wrapped
portions in:
// clang-format off
...
// clang-format on
There may be other locations that are currently not tickled by running
clang-format.

Silence MSVC C4100 (unused formal parameter) to fix breakage from recently added testcase. This warning is silenced in many files throughout googletest, but was not needed here until this testcase was added.

Fix the ACTION* macros to allow for more than 10 arguments in the action.
Only the first 10 will be passed as individual arguments as `argN`, but the rest
can be accessed from the `args` tuple.

None of these are strictly needed for correctness.
A large number of them (maybe all of them?) trigger `-Wdeprecated`
warnings on Clang trunk as soon as you try to use the implicitly
defaulted (but deprecated) copy constructor of a class that has
deleted its copy assignment operator.
By declaring a deleted copy assignment operator, the old code
also caused the move constructor and move assignment operator
to be non-declared. This means that the old code never got move
semantics -- "move-construction" would simply call the defaulted
(but deprecated) copy constructor instead. With the new code,
"move-construction" calls the defaulted move constructor, which
I believe is what we want to happen. So this is a runtime
performance optimization.
Unfortunately we can't yet physically remove the definitions
of these macros from gtest-port.h, because they are being used
by other code internally at Google (according to zhangxy988).
But no new uses should be added going forward.
Allow construction of an Action from a callable of zero args
Action already allows construction from a callable with the same args as the mocked function, without needing to wrap the callable in Invoke. However, if you don't care about the arguments to the mocked function you need to either accept all of them or wrap your callable in InvokeWithoutArgs. This change makes both of those unnecessary, since it allows you to pass a no-args callable to Action directly.

Use standard C++11 integer types in gtest-port.h.
Remove testing::internal::{Int,Uint}{32,64} in favor of types
guaranteed to be in <cstdint> since C++11.
Tests for built-in integer type coverage are switched from
{Int,Uint}64 to [unsigned] long long, which is guaranteed by
C++11 to exist and be at least 64-bit wide.

Add a matcher `testing::ReturnRoundRobin` which, on each call, returns the next element in the sequence, restarting at the beginning once it has reached the end.

Remove legacy support for signed wchar_t and unsigned wchar_t.
Clang now errors out on these types as well by default. Rather than making the
condition for these types even more complicated, just remove the tests covering
these types since they don't seem to justify the maintenance burden. We
can reasonably expect these types to work in compilers that support them
without needing specific tests for them since they are treated as standard
integral types.

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.

Refactor the `Invoke` and `InvokeWithoutArgs` actions:
- Replace pump'd classes and functions with templates.
- Make the polymorphic actions be polymorphic functors instead.
- Fix Invoke(Callback*) to work with subclasses of the callbacks, instead of trying to diagnose that in gmock_doctor.

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.
