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:

P1: open IPv4 port (FAIL)
P0: close IPv4 port

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).

Add an "after fork, before exec" callback
Summary:
In rare cases, it is required to run code **in the child process**, before it calls `exec()` because you need to change the state of the process **before** the child binary gets to run. This diff adds a callback to permit this. The callback is deliberately harder to use than an `std::function`, because you **REALLY HAVE TO KNOW WHAT YOU ARE DOING** to use this. And you have to check your work three times. Even glog `LOG()` must not be called from inside this callback. Your random library of choice is also probably unsafe.
This diff is primarily applicable to job managers and shells. For example, these tasks benefit from this callback: adding a child to a Linux `cgroup`, twiddling its various POSIX process attributes.
Implementing a correct callback for the post-vfork environment is fraught with peril. Read http://ewontfix.com/7/, and the docstrings in this diff.

- return ceil((double(sizeof(IntegerType) * CHAR_BIT) * M_LN2) / M_LN10);
+ return (unsigned int)(ceil(sizeof(IntegerType) * CHAR_BIT * M_LN2 / M_LN10));
In addition to adding the cast to destination type, I have also removed the unnecessary cast to double of the first product (there is not risk that it will overflow, and no need to promote to double, there), and I have also removed the grouping parentheses, since the standard left-to-right evaluation works just fine here.

Summary: This changes ReadMostlySharedPtr API to have 3 types: MainPtr, WeakPtr, SharedPtr. MainPtr and SharedPtr are equivalents of std::shared_ptr, and WeakPtr is an equivalent of std::weak_ptr. The only difference is that it can only be a single MainPtr, and while it's alive copying SharedPtr/WeakPtr or WeakPtr doesn't require atomic operations (and thus can be more performant than std::shared_ptr). Unlike original ReadMostlySharedPtr API, there're no thread-safety guarantees between reset() and getShared() for ReadMostlySharedPtr.

the third argument is zero, and causes a failure when testing with an
UBSAN-enabled binary (-fsanitize=undefined).
Before this change, the buck-run test below would evoke this failure:

Make goodMallocSize always use nallocx
Summary: `goodMallocSize` is used extensively in `folly` data structures,
especially for containers optimized for small contents, such as
`fbstring` and `small_vector`.
However, it makes the design decision to align the allocation size to
a x86 cache line, forcing a minimum allocation size of `64` bytes,
despite jemalloc can provide smaller size classes (8, 16, 32,
48). This causes a large discontinuity between small contents that can
be inlined and heap-allocated contents:
- For `fbstring`, a string of 23 bytes (including terminator) occupies
24 bytes (`sizeof(fbstring)`), a string of 24 bytes occupies 24 + 64
+ allocation overhead when it could be 24 + 32 + allocation
overhead. The waste is more than 50%.
- For `small_vector<uint32_t, 1, uint32_t>`, for instance, a vector
with 1 element occupies 12 bytes, a vector with 2 elements occupies
12 + 64 + allocation overhead when it could be 12 + 8 + allocation
overhead. The waste is more than 250%.
With this diff we just trust jemalloc and always use `nallocx`. If a
data structure need cache-line alignment it should be implemented at
its level.

Fix Build: folly/test/ThreadLocalTest
Summary: [Folly] Fix Build: `folly/test/ThreadLocalTest`.
The problem is that the to the shared lib used in the test is hardcoded. It's a relative path, so that's nice, but it has too many assumptions about where the build system deposits test binaries.
Instead, let the code simply look for the shared lib in the same directory as the test binary. This makes fewer assumptions on the build system.
