Mark ACTION_Pn()-generated functions as must-use-result.

This catches when a client creates an action and discards it, thinking that the action has actually been applied to something.

This will help people who make the mistake of defining, for example, both `void Use(Foo*)` and `ACTION(Use) { Use(arg); }` for later application to a Foo.  With such an overload, a client may then write `Use();`, forgetting the param and being confused why nothing happens.

This also catches when a client defines their own action in terms of an ACTION()-generated one, invokes the ACTION's builder, and then fails to invoke the resulting action, thinking it's operating on the outer action's parameters.

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

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.

The documentation for IsDebuggerPresent says that one just should
include windows.h, as that one is an umbrella header that includes
the header that declares IsDebuggerPresent. In older Windows SDKs,
debugapi.h didn't exist and IsDebuggerPresent was declared in
winbase.h (also included by windows.h).

This should fix issue #2822 properly.

This reverts commit a9f6c1ed.

That commit cannot fix the issue it sets out to fix.

The original issue, #2822, was that building with a toolset
targeting XP compatibility is missing the debugapi.h header -
as debugapi.h didn't exist in older Windows SDKs.

Commit a9f6c1ed misinterpreted
the Microsoft documentation about IsDebuggerPresent. The information
about which header to use, "debugapi.h (include Windows.h)" means
that the function declaration currently lives in debugapi.h, but
for compatibility, just include the Windows.h umbrella header.
In older Windows SDKs (e.g. the v6.0a SDK), IsDebuggerPresent
is declared in winbase.h, and debugapi.h doesn't exist at all in those
versions.

Including Windows.h with a different capitalization than the existing
include won't help finding headers that don't exist.

Including Windows.h with a capital W breaks cross compilation with mingw
toolchains, where the header always has been spelled with a lower case
W. When building on native windows, the file system is case insensitive
and the capitalization doesn't matter.

This fixes issue #2840.

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:

In file included from .../googletest/test/googletest-death-test-test.cc:33:

This matches other changes made elsewhere in the googletest codebase,
such as 306f3754. Perhaps those previous changes did not consider
test code.
