Fix `-Wgnu-zero-variadic-macro-arguments` in GMock
Passing zero arguments to the variadic part of a macro is a GNU
extension and triggers warnings when build projects using GMock with
`-pedantic`.
- Fix uses of `GMOCK_PP_INTERNAL_16TH` to always receive at least 17
arguments. (this was triggered when `GMOCK_PP_NARG` or `GMOCK_PP_HAS_COMMA`
were used with an argument containing no commas).
- Fix `GMOCK_PP_HEAD` to append a dummy unused argument so that
`GMOCK_PP_INTERNAL_HEAD` always has two arguments.

Explicitly define copy constructors used in googletest tests
As of C++11, providing a user-declared copy assignment operator should
suppress the availability of an implicit default copy constructor.
Classes that provide (or delete) a copy assignment operator must provide
their own copy constructor if one is desired. This may be an explicit
default copy constructor if appropriate.
As googletest is a C++11 codebase, this change should be made without
qualification.
This addresses the -Wdeprecated-copy warnings issued by trunk clang:
While compiling googletest/test/googletest-death-test-test.cc:

This matches other changes made elsewhere in the googletest codebase,
such as 306f3754a7. Perhaps those previous changes did not consider
test code.

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.

Add GTEST_ALLOW_UNINSTANTIATED_PARAMTERIZED_TEST to mark a paramaterized test as allowed to be un-instantiated.
This allows test suites, that are defined in libraries and, for other reasons, get linked in (which should probably be avoided, but isn't always possible) to be marked as allowed to go uninstantiated.
This can also be used to grandfather existing issues and expedite adoption of the checks with regards to new cases before they can be fixed.

Add a breadcrumb about nullopt comparison near the Optional() matcher.
Also add a note about how otherwise-spurious 'Eq()' may be needed in some cases. Without this, something like Field(&MyStruct::optional_field_without_equals_equals, absl::nullopt) doesn't work - it converts the nullopt to an optional<> of the non-equalable type, and fails to select the operator==(optional<>, nullopt_t) overload. The Eq() lets the type persist later into the match.

Clone+exec death test allocates a single page of stack to run chdir + exec on.
This is not enough when gtest is built with ASan and run on particular
hardware.
With ASan on x86_64, ExecDeathTestChildMain has frame size of 1728 bytes.
Call to chdir() in ExecDeathTestChildMain ends up in
_dl_runtime_resolve_xsavec, which attempts to save register state on the stack;
according to cpuid(0xd) XSAVE register save area size is 2568 on my machine.
This results in something like this in all death tests:
Result: died but not with expected error.

Split the scoped trace examples into two snippets.
This doesn't have an effect in the github markdown renderer, but in some other renderers/templates, this leads them to be independently copy-pastable. In particular, the markdown rendering that Google uses internally has a copy button for each code snippet, which, before this change, would copy both lines. Bad copy button, no cookie! After this change, there will be two such buttons, one per line, and clicking a copy button will copy only the one snippet it is next to, and not the other. This is desirable because nobody will ever want to copy both lines, only one or the other.
