Add absl::FunctionRef, a type analogous to the proposed C++23 std::function_ref.

Like std::function, FunctionRef can be used to type-erase any callable (invokable) object.  However, FunctionRef works by reference: it does not store a copy of the type-erased object.  If the wrapped object is destroyed before the FunctionRef, the reference becomes dangling.

FunctionRef relates to std::function in much the same way that string_view relates to std::string.

Because of these limitations, FunctionRef is best used only as a function argument type, and only where the function will be invoked immediately (rather than saved for later use).  When `const std::function<...>&` is used in this way, `absl::FunctionRef<...>` is a better-performing replacement.

Try to become idle only when there is no wakeup.

Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch.  Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads.  For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.

Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup.  For
idle threads the net effect should be the same.  For active, threads this will
be more efficient.

Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping.  This should result
in more accurate idleness and more efficient release of thread resources.

Fix AtomicHook init-order fiasco under MSVC 2019.

On this platform, constexpr static init sometimes happens after dynamic init =/.  When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone.  This works even when constexpr static init goes first since all uses of AtomicHook should have static storage duration and be zero-initialized.

Avoid the compiler reloading __is_long() on string_view(const string&)

The underlying cause is that the compiler assume a scenario where string_view is created with placement new into memory occupied by the input, so the store to 'ptr' can affect the value / result of size(); i.e., __is_long() reloads the __size value).

Example code: string_view1 demonstrates the problem, string_view2 DTRT.

=== string_view1
struct string_view1 {
    string_view1(const char* ptr, size_t n) : ptr(ptr), n(n) {}

Work around MSVC 2019 compiler bug related to constexpr in optional_test.
The change in optional_test is necessary to avoid another bug on MSVC
complaining about accessing invalid member of union, and also makes the test

Update iter.position when moving up the tree in rebalance_after_delete.

This field isn't read after the first iteration in rebalance_after_delete, and I think it's not a correctness issue, but it is read in try_merge_or_rebalance and potentially affects rebalancing decisions so it can affect performance. There's also an extremely unlikely potential for undefined behavior due to signed integer overflow since this field is only ever incremented in try_merge_or_rebalance (and position is an int). Basically though, I just don't think it makes sense to have this invalid iterator floating around here.

* [bazel] Add fixes for --incompatible_load_cc_rules_from_bzl

Starting with Bazel 1.0 (September 2019), C++ rules will need to be
loaded from the @rules_cc repository. This change adds the required
loads for that. For full compatibility, we will need versions of
googletest and google-benchmark that also includes these loads.

* Run buildifier again after merge

Inside of absl::string_view::copy, use absl::string_view::traits_type::copy instead of std:copy to do the actual work.  This both follows the C++ standard more closely and avoids avoid MSVC unchecked iterator warnings.
