Fix AsyncSSLSocket handshake error reporting.
Summary:https://www.openssl.org/docs/manmaster/ssl/SSL_get_error.html
OpenSSL errors are a pain to deal with and we were handling several cases
incorrectly, resulting in a ton of "DH lib" errors when none were likely
actually DH lib errors.

Add conversion constructors for Future
Summary:previously we were not able to do
Future<Base> f = makeFuture<Derived>();
This is because Future did not declare a conversion
constructor.
Adding a proper conversion ctor for Future is very
tricky because of the way Core is managed under the hood.
Core is not movable, and cannot be moved otherwise we
would have to retain pointers to the Future and Promises which
pointed to a particular core. This would be inefficient.
Instead we compromise and allow a very small subset of conversions
from objects whose templated types are convertible and also the
sizes of their Cores are also the same. As a result, we can
convert between types like unique_ptrs however not always between
full objects.

Fix folly::Singleton to work in dynamically linked binaries
Summary:This implements StaticSingletonManager which is then used to create all leaked Meyers singletons.
StaticSingletonManager is a singleton itself, which is created in a separate compilation unit (Singleton.cpp) and so we can be sure that other compilation units will always see a single instance of StaticSingletonManager, even if linked dynamically.
StaticSingletonManager then keeps a dictionary of typeid -> object pointer, which is used to de-duplicate same singleton being re-created from different compilation units (linked dynamically), usually because of code inlining.

Modification to futures to remove deadlock in certain use cases for getVia(executor).

In effect: f.via(executor).getVia(executor); deadlocks. This can be a problem if the code is hidden in a library and the precise semantics are unclear. This diff adds a test that exposes the problem and a fix by forcing waitVia to add a callback that will satisfy the new exector, ensuring that drive() has a callback to trigger once the future is satisfied.

Relax HHWheelTimer::destroy assertion to accommodate SharedPtr
Summary:
HHWheelTimer's auto-pointers are kind of funny. You can do something like this:
```
HHWheelTimer::UniquePtr p = ...;
// create a SharedPtr from UniquePtr
HHWheelTimer::SharedPtr s(p);
// create another SharedPtr from raw ptr
HHWheelTimer::SharedPtr s(p.get());
// No problem.
If you do this:
HHWheelTimer::SharedPtr p = ....;
// this leaks
```
Why? Because SharedPtr is only have of std::shared_ptr. It's the refcounting half. But when the last SharedPtr goes out of scope, it **does not** invoke HHWheelTimer::destroy().
So code like this is possible/expected:
```
MySweetObj::MySweetObj(HHWheelTimer::SharedPtr s) {
s_ = s;
s_.scheduleTimeout(a, b);
}
{
HHWheelTimer::UniquePtr p = ...;
obj = MySweetObj(p)
// But what if I decide to kill p:
p.reset();
}
```
Since MySweetObj takes a SharedPtr and holds it, it can reasonbly expect that it can schedule timeouts on it, and the HHWheelTimer will not be deleted until it releases the SharedPtr. This is true, but the above code would hit the assert that count_ == 0.
Instead, relase the check that count_ == 0 only if there are no extra outstanding SharedPtrs.

folly/futures: fix early release of non-embedded callbacks
Summary:
folly::Future (more precisely folly::detail::Core) can store
callback functors (typically lambdas) up to a certain size
(8*sizeof(void*)) inside the main object. Only bigger functors
are stored in the std::function object in folly::detail::Core,
which will put them on the heap.
The behaviour of folly::Future is slightly different depending
on whether the callback can be embedded in the main object
or not. Small functors will be destructed after the callback
is executed. Functors too big to fit in the lambda space in
the Core object will be deleted when Core is deleted.
Some code assumes that functor objects are deleted as soon
as the callback has been executed. The implementations of
folly::Future::collect and variants do so. If you switch
off this optimisation temporarily (which can be done easily
by setting lambdaBufSize in folly/futures/detail/Core.h to
0), a number of unit tests fail.
Given that the lambda buffer is reasonably large, most
functors can be stored in the Core object. The different
behaviour for very large lambdas may not have been observed.
This diff fixes the inconsitent behaviour.
Firstly, it changes the unit test Future:finish to explicitly
check that the callback functor is deleted after the callback
has been executed. This should be tested, because this
behaviour is assumed in other parts of the futures
implementation (e.g. Future::collect et al.).
Secondly, it adds another unit test Future:finishBigLambda,
similar to Future:finish. The lambda captures much more data
to make sure the lambda won't be stored in the Core object,
but in the std::function object inside Core. The test verifies
that the behaviour is the same, i.e. the callback functor
is destructed after the callback has been executed.
Thirdly, it fixes Core and makes sure that functors of any
size are destructued after the callback has been called. The
new unit test fails without this.

Summary:
[Folly] `ConditionallyExistent<typename>`.
For when we need extra member fields in dbg builds, but want to save the space in opt builds. Or other situations along similar lines, but with perhaps another the statically-known condition.
Conditional compilation can have some nasty side-effects. Best to avoid it. Let the compiler see everything, rather than having the preprocessor ruin our day. Let the optimizer remove code that will never be called, after the compiler has seen it. Let us have a single AST in our source file, not one AST for dbg and one for opt, or other statically-known conditions.

Kill writeTerminator in fbstring
Summary:
`writeTerminator` needs to determine the string category, and in the small case, also its size. This information is often known, but the compiler cannot optimize it away especially if `capacity_` was just overwritten. Also, some occurrences are just redundant. We can remove the latter and specialize the former.
Small operations such as `push_back` are up to 40% faster.
