Remove a RequestContext deadlock
Summary:
It is not unusual to write a RequestData that will send a request to a backend service upon destruction (for example, to log the request data). This typically involves calling EventBase::runInEventBaseThread() to do the logging. Normally, if you wait until the RequestContext is destructing for this to happen, everything works fine. However, if you explicitly call clearContextData(), then this can cause a deadlock. clearContextData() holds the write lock on the data_. Imagine the NotificationQueue thread tries to set the context (for some other reason), and it is waiting on the read lock on the data_. It does so while holding a lock on its own queue. Now, the clearContextData() calls the destructor while holding the write lock on data_, and the destructor calls runInEventBaseThread, which grabs the queue's lock. Deadlock.
This can either be fixed in NotificationQueue or RequestContext. I decided to fix it in RequestContext because there may be other deadlocks that don't involve NotificationQueue (see the test plan).
There are other deadlocks in RequestContext if you call write methods in RequestData::onSet or onUnset. But fixing this would require a massive perf regression (I imagine using shared_ptr instead of unique_ptr, and copying the ptrs under readlock and calling the callbacks after releasing the lock - yuck!) So instead, warn people against doing that.

Add a method to AsyncSSLSocket to supply connect timeouts
Summary:
The current method to supply connect timeouts to AsyncSSLSocket
is to supply only the max connect + ssl connect time.
However in some cases when connect time is known, it is desirable
to supply it so that if connect does not succeed in connect time
we can error out quicker and retry.
This adds a new method for connect time in addition to the total
Connect time.
An alternative to this would be to create a AsyncSocket, connect it
and then pass it's fd to AsyncSSLSocket, however that approach does
not work well when TFO is being used, because TFO State is a part of
the AsyncSocket's state and that is not encapsulated with the fd transfer.
We could move the state around, but that is error prone, and this is much
simpler and isolated to AsyncSSLSocket.

New C++17 backport: folly::enable_shared_from_this
Summary:
C++14 has no direct means of creating a std::weak_ptr, one must always create a (temporary) std::shared_ptr first. C++17 adds weak_from_this() to std::enable_shared_from_this to avoid that overhead.
Alas code that is meant to compile under different language versions cannot rely on std::enable_shared_from_this::weak_from_this().
This new utility class uses SFINAE to call std::enable_shared_from_this<T>::weak_from_this() if available. Falls back to std::enable_shared_from_this<T>::shared_from_this() otherwise.
Use as a drop-in replacement for std::enable_shared_from_this where weak_from_this() is desired.

The multi-poster baton (SinglePoster = false) can be handed over by multiple concurrent posters, where redundant post()-s are idempotent but if a post() arrives after the baton is reset() then it unblocks the waiter.

Detect identity conversion in toDynamic
Summary:
D4499520 added typedefs to `dynamic` which made it start matching
tests for ranges/containers. However, the typedefs are unconditional on the
actual contents of the `dynamic`. This made toDynamic(dynamic) select the
range-based conversion operator, always, which immediately asserts when
trying to do range-based iteration over an Object or a primitive. Add tests
to the converters that enable/disable depending on whether the object is
already a `dynamic` and early-out in that case.

Benchmark string copying via the formatter
Summary:
Using the formatter is always much slower than using the copy constructor (News at 11).
Comparing the two idioms for formatting out a single string input:
* the unsafe method (`format(theString)`) is (annoyingly) fastest for small strings; probably because cache-hits dominate the need to inspect every character to see if it is `{` or `}`
* the safe method (`format("{}",theString)`) is fastest on large strings (crossover at roughly 256 bytes)
* there isn't a lot in it between 64 and 512 bytes.

execute callbacks as rvalue references
Summary:
Callable objects may implement a separate `operator()` for when
they are called as rvalue references. For example, `folly::partial`
will move captured objects to the function call when invoked as
rvalue reference. That allows e.g. to capture pass a `unique_ptr`
to `folly::partial` for a function that takes a `unique_ptr` by
value or rvalue-reference.
Callbacks for `folly::Future`s are only ever executed once. They
may consume captured data. If the callback is an object that
implements a `operator()() &&`, then that one should be invoked.
This diff makes sure, callbacks passed to `folly::Future` are
invoked as rvalue references.

Clear OpenSSL error stack after loading certificate file.
Summary: SSL_CTX_load_verify_locations interally end up using X509_load_cert_crt_file, which has an unchecked call to X509_STORE_add_cert. This can fail and add an error to the error stack without causing SSL_CTX_load_verify_locations to return an error.

Don't use Pthread in EventBase
Summary:
Pthread is currently a dependency of Folly that is not really necessary on Windows, or even with standard C++ for the most part, so start work on killing it in Folly.
This switches EventBase to using `std::thread::id`'s instead, which also means we aren't reliant on the implementation detail that thread id 0 is invalid. Well, we are, but it's now the standard library's fault not ours.
