* `any_invocable`: Clean up #includesDino Radakovic2024-05-081-1/+1
| | | | | | | | | - remove [<initializer_list>](https://en.cppreference.com/w/cpp/header/initializer_list) from internal header. It declares `std::initializer_list`, `std::begin` and `std::end`, none of which are used there - add `absl/base/attributes.h` to the internal header because it provides `ABSL_FALLTHROUGH_INTENDED` - add [<functional>](https://en.cppreference.com/w/cpp/header/functional) to the public header, because it provides `std::reference_wrapper` PiperOrigin-RevId: 632018125 Change-Id: Icf7a9c8a920c9c076ef416ea80995e3a81ce3e81

* `any_invocable`: Delete obsolete reference to proposed standard typeDino Radakovic2024-05-071-5/+5
| | | | | | | | The comment calls if `any_invocable`, but the standard ultimately chose [`move_only_function`](https://en.cppreference.com/w/cpp/utility/functional/move_only_function/move_only_function).

| | | | | | | | AnyInvocable is a C++11 compatible equivalent of the C++23 [std::move_only_function](https://en.cppreference.com/w/cpp/utility/functional/move_only_function/move_only_function). Although this implementation matches an intermediate draft revision of the standard (http://wg21.link/p0288r5), it is neither a standard tracking type nor a seamless backfill type.

PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

-- a9ac6567c0933d786d68c10011e3f3ff9deedf89 by Greg Falcon <gfalcon@google.com>: 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.
