Optimal make_integer_sequence
Summary:
[Folly] Optimal `make_integer_sequence`.
When the builtin `__make_integer_seq` is available, use that. It is the most optimal implementation.
Otherwise, use a tweaked divide-and-conquer implementation. Designed to reuse more template instantiations than the straightforward divide-and-conquer approach in libstdc++ >= 6. And definitely not linearly recursive as in libstdc++ < 6.
Illustrating with an example. Let `M` be whatever template type implements `make_integer_sequence`. For `M<17>`, libstdc++ < 6 does linear recursion (least optimal), instantiating `M<16>`, `M<15>`, ..., `M<1>`. libstdc++ >= 6 does straightforward divide-and-conquer recursion, instantiating `M<8>` and `M<9>`, recursing into `M<4>` and `M<5>`, recursing into `M<2>` and `M<3>`, recursing into `M<1>`. Our implementation does a variant of divide-and-conquer recursion to maximize reuse, instantiating `M<8>` and `M<1>`, recursing into `M<4>`, recursing into `M<2>`.
Implementation derived from `fatal/type/sequence.h`.

Current `IsOneOf` implementation does unnecessary work because it instantiates all of the possible template specializations, even if type is same as the first of the tested ones. E.g.

```
IsOneOf<char, char, int, float>
IsOneOf<char, char, int>
IsOneOf<char, char>
IsOneOf<char>

ConcurrentHashMap
Summary:
A ConcurrentHashMap with wait-free readers, as in Java's ConcurrentHashMap.
It's a pretty generic closed-addressing chaining hashtable, except find() uses two hazard pointers
to do hand-over-hand traversal of the list, so it never takes a lock.
On rehash, only the part of the chain that remains the same (i.e. is still hashed to the same bucket)
is reused, otherwise we have to allocate new nodes.
Reallocating nodes means we either have to copy the value_type, or add in an extra indirection
to access it. Both are supported.
There's still a couple opportunities to squeeze some more perf out with optimistic loading
of nodes / cachelines, but I didn't go that far yet, it sill looks pretty good.

Move OpenSSL locking code out of SSLContext
Summary:
OpenSSL 1.1.0 deprecates the callback based locking setup in favor
for platform native mutexes.
Added `OPENSSL_init_ssl` in the OpenSSL portability module for OpenSSL API < 1.1.0. This implements
the standard OpenSSL library initialization routines (taken from SSLContext::initializeOpenSSL).
Added `OPENSSL_cleanup` in the OpenSSL portability module for OpenSSL API < 1.1.0. This implements
the cleanup routine from SSLContext::cleanupOpenSSL.
Removed `SSLContext::SSLLockType`. Replaced with `folly::ssl::LockType`.

Fix double-free in DynamicConverter
Summary:
If an exception is thrown during the construction of value in a container, then the Transformer iterator will not successfully reconstruct a cache_ object after explicitly calling its destructor (due to the exception being thrown), which results in a double-free when cache_ is destroyed as part of Transformer's destructor.
Conveniently, there exists a piece of code designed to solve just this problem: folly::Optional. Replace cache_ and valid_ with folly::Optional.
This also fixes the unnecessary requirement that container value types have default constructors, since cache_ is no longer default constructed inside of Transformer.

Replaceable
Summary:
An instance of `Replaceable<T>` wraps an instance of `T`.
You access the inner `T` instance with `operator*` and `operator->` (as if
it were a smart pointer).
`Replaceable<T>` adds no indirection cost and performs no allocations.
`Replaceable<T>` has the same size and alignment as `T`.
You can replace the `T` within a `Replaceable<T>` using the `emplace` method
(presuming that it is constructible and destructible without throwing
exceptions). If the destructor or constructor you're using could throw an
exception you should use `Optional<T>` instead, as it's not a logic error for
that to be empty.

replace getnameinfo with inet_ntop in v6 string formatting
Summary: Some implementations of getnameinfo are triggering reverse DNS lookups despite us specifying NI_NUMERICHOST. Avoid all that by instead producing our string representations of v6 addresses manually via inet_ntop and if_indextoname.

Update CachelinePadded
Summary:
The C++ standard doesn't guarantee alignment of things bigger than std::max_align_t which is typically 16 bytes. This means that to ensure something is the only thing on a cache-line we need padding on each side of it to exclude anything else.
CachelinePadded<T> will now be larger than it was before, and reinterpret_cast to/from T is no longer valid.

Add support for closing a TemporaryFile early
Summary:
The file itself will still get removed when `TemporaryFile` is destroyed, but closing it before then allows it to be read when on Windows, because `TemporaryFile` opens the temporary file with `O_EXCL`, so Windows denies read access of the file to everything else.
This is needed to fix one of the AsyncFileWriter tests on Windows.

Force string pooling to workaround a codegen bug
Summary:
There are bugs in MSVC's codegen that causes `StringPiece`'s evaluated in a `constexpr` context to have the start pointer point to one copy of the string and the end pointer point to another. Using the `StringPiece` at compile-time is perfectly fine, it just has the wrong values at runtime.
We can work around this issue by enabling string pooling in all modes.
