logging: if folly::format() fails, also log the arguments
Summary:
If the folly::sformat() call fails in an FB_LOGF() statement, make a
best-effort attempt to log the format arguments as well, in addition to the
format string. For each argument, folly::to<std::string>() is use if it is
supported for this argument.

even if the format string was incorrect.

logging: add support for streaming operators
Summary:
Update the logging library so that FB_LOG() and FB_LOGF() also accept
streaming style arguments:
FB_LOG(logger) << "logs can be written like this now: " << 1234;
FB_LOG(logger, "both styles can be used") << " together";
FB_LOGF(logger, "test: {}, {}", 1234, 5678) << " and with FB_LOGF() too";
Streaming support does make the upcoming XLOG() macros more complicated to
implement, since the macro has to expand to a single ternary `?` expression.
However I was able to come up with a solution that works and has minimal
overhead.

fix timeWaiting computation in TimeUtil
Summary:
Some of the code in TimeUtil.cpp computes how long the current thread has spent
waiting to be schedule on the CPU, so we can discount this time when testing
timeout behavior.
It appears that this code has been broken for a fairly long time. Older Linux
kernels reported values in /proc/<pid>/schedstat using jiffies. However, it
appears that this was changed in Linux 2.6.23 to report values using
nanoseconds. (It looks to me like this was changed in commit
425e0968a25f,
which purports to simply be moving code from sched.c to sched_stats.h,
but it appears to also have also changed this behavior.)

kernels.

Summary: This diff adds a Traits template parameter to IndexedMemPool that allows more control over the lifetime management of individual elements, including mixes of lazy and eager recycle semantics (or colocation of different classes of data inside a single element). It also arranges that an index is not reported as isAllocated() until it has been passed to Traits::initialize and passed to Traits::onAllocate at least once, so code that is traversing valid indexes doesn't need to deal with the post-initialize but pre-onAllocate state (it must still deal with indexes that reported isAllocated() as true but have since been passed to onRecycle).

Let map-related functions be templated over key types
Summary:
[Folly] Let map-related functions be templated over key types.
This supports the case where map members like `find` may be overloaded or templated on types other than the map's `key_type const&`.
In C++14, standard library map types gain template overloads for `find` and for other members, permitting lookups without constructing `key_type` instances. This is useful primarily when `key_type` is expensive but another object type comparable with `key_type` is inexpensive. As a common example, a `key_type` of `std::string` is expensive in the general case because it allocates storage on the heap but `std::string_view` (C++17), when constructed with non-allocated `char const*, std::size_t`, would be inexpensive.

Added folly::hint_emplace_iterator to folly/Iterator.h
Summary:
In contrast to Container::insert(), for any STL container class, Container::emplace() does not have an overload that takes a Container::iterator as its first parameter. (The reason is to prevent ambiguity with respect to target class constructor parameters.) Instead, container classes have a separate emplace_hint() function.
Because of this separation, folly::emplace_iterator would fail to perform hinted emplacement in constructs where std::insert_iterator would perform hinted insertion.
This diff adds a new class, folly::hint_emplace_iterator(), and corresponding convenience function, folly::hint_emplacer(), which calls Container::emplace_hint() rather than Container::emplace().
It would have been trivial to copy&paste the existing folly::emplace_iterator class and simply replace the emplace() call with emplace_hint(), but I did not like the large amount of code repetition. So I decided to do some refactoring and move the emplace()/emplace_hint()/emplace_front()/emplace_back() calls into separate trait classes, and replace emplace_iterator()/hint_emplace_iterator()/front_emplace_iterator()/back_emplace_iterator() with suitable type aliases.

Shift the job of defining NOMINMAX into source rather than the build system
Summary:
This makes it easier to consume Folly from a non-cmake project.
Note that this also requires making libevent, which was previously categorized as a semi-portable header into a non-portable header, meaning it can't be referenced directly. (libevent includes `Windows.h` in one of its headers -_-....)

fix PicoSpinLock for aarch64 and allow PackedSyncPtr to compile for aarch64
Summary:
Looks like we never tried to compile or run the PicoSpinLock under aarch64. There were two problems:
if sizeof(IntType) is 64, we try to do
1 << 63
in lock and unlock. This doesn't compile because sizeof(1) is 32.
Also for try_lock, we were returning the data instead of checking for the locked bit.

Make a few adjustments to the compile config for the CMake build
Summary: This includes adding options to toggle `/std:c++latest`, and `WIN32_LEAN_AND_MEAN`, along with giving a nice drop-down selector to `MSVC_FAVORED_ARCHITECTURE` when configured via the GUI, dropping `_WINSOCK_DEPRECATED_NO_WARNINGS` as it wasn't needed, and re-enabling warnings 4365 and 4775 within the scope of the standard library.
