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.

Replace uses of ACTION_TEMPLATE and ACTION_P with manually written functors.
The latter provide better error diagnostics.

Workaround static assert in early versions libc++

The error is "Attempted to construct a reference element in a tuple with an
rvalue". We can fix this by putting everything into a non temporary tuple_args
and implitly convert to the other tuple types. This avoids binding an rvalue
reference to an lvalue reference inside the tuple.

Fix DoAll to work with move-only sink arguments.

This changes types of the first n - 1 actions so that they only get a readonly
view of the arguments. The last action will accept move only objects.

Mention matchers as an alternative to assertions in subroutines.

Matchers are often the better choice - they can provide more informative error messages and circumvent all of the complexity described in this section.

The tiny-dnn project has changed the test framework (https://github.com/tiny-dnn/tiny-dnn/commit/d0d35ca2f4e75b3f647787e19ee7f31d0784b398) and removed the googletest usage.

Removing it from the "Who is Using Google Test?" list so as to keep it accurate.

Updated documentation for Value-Parameterized Tests: Per-default, a TEST_P without a corresponding INSTANTIATE_TEST_SUITE_P now causes a failing test.
