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.

folly: ubsan: replace undefined call through reinterpret-cast fn-pointer with std::function
Summary:
This code casts function pointers to void(*fn)(void*) and calls
functions through that type. Calling functions through a different
pointer type is undefined behavior. Casts were used to avoid memory
allocations.
`std::bind` needs a memory allocation - so it's avoided in EventBase.
std::function<void()> x = std::bind(fn, args);
`std::function` should use small object optimizations when possible and embed the functor in the body of `std::function`.
On GCC 5.0 and forward small lambdas don't need memory allocations
(lambdas being tiny structures - two pointers in this case - and a
function operator).
std::function<void()> y = [=] { fn(args); };
On GCC 4.7 .. 4.9 functors for which __is_location_invariant<Func> is
true also don't need memory allocations.
Remove undefined behavior by using a `SmallFunctor` which leverages `std::function`'s small object optimization.

When a large number of processes concurrently bind and close `AsyncServerSocket`s with `port=0` (for example in tests) binding the IPv4 socket on the same port bound with the IPv6 socket can currently fail, because sockets are closed in the same order as they are opened, which makes the following scenario possible:

Fix EventBaseLoopController destruction races
Summary:
Existing scheduleThreadSafe implementation had 2 potential races on destruction:
1. (very unlikely) insertHead is complete, but fiber loop is already running on another thread, so it finishes processing all of the fibers, destroys FiberManager or EventBase or both. By the time we get to scheduleThreadSafe EventBaseLoopController is already destoyed
2. (more likely) scheduleThreadSafe is complete, but FiberManager loop which is already running, picks complete fiber, finishes the processing. After that FiberManager may be destoyed. So when EventBase actually executes the callback FiberManager is already dead.
This solution fixes both races. Holding the alive shared_ptr when completing sheduleThreadSafe assures EventBase can't be destoyed until its completed (or it won't try to schedule anything after EventBase was destroyed). Locking alive weak_ptr in the EventBase loop callback ensures FiberManager and thus EventBaseLoopController were not destroyed yet (they can be destoyed only by the same thread which is running EventBase loop).

Summary:
[Folly] Use `SharedMutex` as the default mutex type in `Synchronized`.
`folly::SharedMutex` is, overall, a faster mutex than `boost::shared_mutex`. Let's upgrade.

Fix automake build

Summary:
This also introduces a new try_get_fast() API which returns ReadMostlySharedPtr.
We should eventually migrate all users onto this API.

Summary: With openssl-1.0.2 and later add support for ALPN. Clients can request NPN only, but the default is to support either (client will send ALPN list, server will send NPN advertisement if ALPN is not negotiated).

Avoid cost of cancelAll
Summary:
This is an experimental diff that may improve the performance of `HHWheelTimer::cancelAll`. If there are no timers to cancel, then it can bail early.
Since perflab is unlikely to be conclusive, and since this diff looks like a strict improvement, I'll proceed with landing it.
