folly::Function: improve conversion of return types
Summary:Treat any return type as convertible to void:
As of C++17, std::function<void(Args...)> can be set to callables
returning non-void types when called with parameters Args....
This diff adds that capability to folly::Function. It also adds
unit tests, not only for ignoring return types, but also for
correctly converting between the return type of the embedded
callabled and the return type of the encapsulating folly::Function.
Allow conversion of one folly::Function type to another one which
declares a return type the original one can be converted to:
E.g. allow to construct a Function<double()> from a
Function<int()> or a Function<Base*()> from a
Function<Derived*()>.

Fix Build: folly after replacing FOLLY_NORETURN
Summary:[Folly] Fix Build: `folly` after replacing `FOLLY_NORETURN`.
Problem 1:
* Clang does not treat `[[noreturn]]` and `__attribute__((__noreturn__))` as the same attribute. When a function is declared twice with the noreturn attribute, both declarations must use either the one syntax or the other; Clang fails if the two declarations mix-and-match. When both `folly/detail/FunctionalExcept.h` and gcc49's `bits/functexcept.h` are both included from the same source, they (now) mix-and-match the attribute syntaxes and Clang emits an error.
* `folly/detail/FunctionalExcept.h` should be included only when `bits/functexcept.h` is unavailable - somehow, both headers were being included.
We fix the latter problem and keep our `[[noreturn]]` syntax.

Introducing folly::Function
Summary:std::function is copy-constructible and requires that the callable that it wraps
is copy-constructible as well, which is a constraint that is often inconvenient.
In most cases when using a std::function we don't make use of its
copy-constructibility.
This diff introduces a templated type called folly::Function that is very
similar to a std::function, except it is not copy-constructible and doesn't
require the callable to be either.
Like std::function, Function is a templated type with template parameters
for return type and argument types of the callable, but not the callable's
specific type. It can store function pointers, static member function pointers,
std::function objects, std::reference_wrapper objects and arbitrary callable
types (functors) with matching return and argument types.
Much like std::function, Function will store small callables in-place, so
that no additional memory allocation is necessary. For larger callables,
Function will allocate memory on the heap.
Function has two more template parameters: firstly, an enum parameter of
type folly::FunctionMoveCtor, which defaults to NO_THROW and determines
whether no-except-movability should be guaranteed. If set to NO_THROW,
callables that are not no-except-movable will be stored on the heap, even
if they would fit into the storage area within Function.
Secondly, a size_t parameter (EmbedFunctorSize), which determines the size of
the internal callable storage. If you know the specific type of the callable you
want to store, you can set EmbedFunctorSize to sizeof(CallableType).
The original motivation of this diff was to allow to pass lambdas to
folly::Future::then that are not copy-constructible because they capture
non-copyable types, such as a promise or a unique pointer.
Another diff will shortly follow that changes folly::Future to use
folly::Function instead of std::function for callbacks, thus allowing to
pass non-copyable lambdas to folly::Future::then.

if (prctl(PR_SET_PDEATHSIG, options.parentDeathSignal_, 0, 0, 0) == -1) {

LLVM generates the following assembly:
```lang=asm
0x000000000040a77b <+347>: mov 0x28(%r14),%rsi
0x000000000040a77f <+351>: test %esi,%esi

0x000000000040a791 <+369>: callq 0x405ad0 <prctl@plt>
```
`%rsi` is a 64-bit register, on the line 1 value of `0x28(%r14)` is loaded to this register. That address points to `options.parentDeathSignal_`, which is a 32-bit value, set to 10 somewhere in a test. After that load:
```
rsi 0x7f000000000a
```
Notice it is not 10 (0xa), there is some garbage value in the upper part of the register. On the line 2, the lower part of this register is checked if it is zero, which corresponds to the first if statement. Then lines 4-8 prepare for `prctl` call. The value of the second argument is passed via `%rsi`, but the upper 32 bits were not cleared. This makes the function call generate `Invalid argument` error.
With the added explicit cast, notice a call `movslq %eax,%rsi`, which moves a signed 32-bit value of `%eax` (which contains `options.parentDeathSignal_`) to unsigned 64-bin `%rsi`:
```
0x000000000040a77b <+347>: mov 0x28(%r14),%rax
0x000000000040a77f <+351>: test %eax,%eax

`Clock` must be one of the types supported by the underlying call to `folly::detail::Futex::futexWaitUntil`; at time of writing these are `std::chrono::steady_clock` and `std::chrono::system_clock`.

folly::FunctionScheduler: Adding capability to reset a function's timer
Summary:Adding support for resetting a specified function's timer.
"Resetting a function's timer" effectively means "canceling whatever next runs it would have had, and treating it as though it were just added".
When `resetFunctionTimer` is called, the specified function's interval (timer) will be reset, and it will execute after its initially-specified `startDelay`. If the `startDelay` is zero, the function will execute immediately, and then be scheduled as before - once every `interval` milliseconds.
Motivation: batch processing of updates, where both a size and time limit are in play. If the size limit is reached, it makes sense to reset the timer for the scheduled function.

Fix warning in MicroLock initialization
Summary:The `init()` function uses the previous value of `lock_`, but that is
uninitialized and the compiler can issue a warning about it. It is
also potentially undefined behavior because it is not guaranteed that
the address of `lock_` is taken before `init()` (in which case the it
would be just an indeterminate value).
Since it is not very useful to initialize only one slot and leave the
others uninitialized, we can just have a single `init()` that
zero-initializes all the slots.

glog depends on gflags, but when the libraries are static, there is
no explicit dependency information available and the linker fails.

configure to add an implicit `-lgflags` for the subsequent glog
tests.

Summary:MicroLock is a full-featured lock that fills the niche that

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.

folly: symbolizer: dwarf: don't fallback to linear scan if address missing from .debug_aranges
