Summary:
[Folly] In-place construction for `Future`.

Using `in_place` as the first argument. Avoid constructing a contained object and then moving it into the `Future`, which may be more expensive, by providing an unambiguous way to specify perfect forwarding.

And a matching overload of `makeFuture` for no particularly good reason.

Summary:
[Folly] Disambiguate the various `in_place` overloads, following C++17.

Forwarding `folly::in_place` is ambiguous because there are multiple overloads and we depend on deduction to choose the correct overload. For example:

```lang=c++
enum struct Err {};
Expected<Expected<int, Err>, Err> val(in_place, in_place, 3); // fails to compile
```

So we must disambiguate the three overloads: the default, the typed, and the indexed.

C++17 defines `std::in_place`, `std::in_place_type<typename>`, and `std::in_place_index<std::size_t>`. Let us mimic that exactly, so that it becomes trivial to swap out our implementations for the standard implementations once we jump to C++17.

Clang's UndefinedBehaviorSanitizer flagged an issue that pushAtMost() could
call `memcpy(dest, nullptr, 0)` if the input was an empty `ByteRange`.  A
default constructed `ByteRange` (or `StringPiece`) will be empty and both its

This updates the `Cursor` and `Appender` code to avoid calling `memcpy()` at

Giuseppe Ottaviano [Mon, 26 Jun 2017 21:42:31 +0000 (14:42 -0700)]
Improve Format's handling of temporaries

Summary:
`FormatValue` holds non-integral objects by reference, which
can cause subtle problems if a formatter is constructed with temporary
arguments and used beyond the expression that constructs it.

With this diff the arguments are perfectly forwarded into a tuple, so
the formatter will take ownership of the temporaries while holding
references to lvalues as before.

The only downside is that now `FormatValue` objects are constructed
every time the formatter is used, rather than only at formatter
construction. This should not be noticeable as those objects'
constructors should just take a reference to the argument.

Note that the format string is still held by reference, but this is
fine because it should almost always be a string literal.

Resolve two issues with folly's clock_gettime() shim on Apple platforms (iOS, macOS, etc.):

When detecting whether folly should define clock_gettime() on Apple platforms, don't assume clock_gettime() is declared in Apple's headers just because MAC_OS_X_VERSION_10_12/__IPHONE_10_0 is defined. Someone might use a newer macOS or iOS SDK (which defines MAC_OS_X_VERSION_10_12/__IPHONE_10_0), but not have clock_gettime() (because _DARWIN_FEATURE_CLOCK_GETTIME isn't set).

When defining a shim for clock_gettime(), don't rely on Apple's clock_gettime() declaration. Instead, shadow Apple's declaration with our own. This prevents folly from inheriting Apple's availability and visibility attributes for clock_gettime().
