Fix double-delete in Singleton::make_mock
Summary:
[Folly] Fix double-`delete` in `Singleton::make_mock`.
In that function, we unconditionally destroy any existing singleton instance of the same singleton. Actually, we must conditionally destroy it - conditionally on one having been created and not yet destroyed.
This problem only rarely appears because it is masked by `delete static_cast<T*>(nullptr)` being a no-op. For example, if we call `make_mock` before actually instantiating the singleton, we call that no-op. The way to make it appear is to instantiate the singleton, and then to call `make_mock` twice in a row. The first call to `make_mock` unconditionally destroys the existing instance (it still should have checked) and the second call does it again, but because the existing instance is not `nullptr`, the second call is a double-delete of a non-`nullptr` instance and crashes. In the simple case, as reproduced in an attached test, the failure is observable with ASAN. In other cases, the double-`free` is tolerated, but the failure may only be observable depending on the singleton object's state - if running the dtor twice fails.

fix dead-lock in Future when executor discards function
Summary:
This diff adds two tests to futures/test/ViaTest.cpp:
viaDummyExecutorFutureSetValueFirst and
viaDummyExecutorFutureSetCallbackFirst. The latter resulted in a
dead-lock before the fix contained in this diff.
It is important that the callback function is destroyed after
it is executed, since it may capture objects (like a Promise)
that should be destroyed (so that e.g. a corresponding Future
throws BrokenPromise). When the callback is executed via an
executor, it is possible that the executor doesn't get around to
executing the task. We shouldn't rely on the task being executed
to do necessary clean-up. That clean-up should (also) happen
when the task (with its captured data) is destroyed (in the
spirit of RIAA).

AutomaticCodec
Summary:
Add codec that does automatic format detection for decompression.
The codec returned by `getCodec(CodecType::AUTOMATIC)` can decompress codecs `LZ4_FRAME`, `ZSTD`, `ZLIB`, `GZIP`, and `LZMA2`.
Additionally, the function `getAutomaticCodec()` allows users to pass their own custom codecs, but the 5 default codecs must also be supported.
We force the default codecs on users because having a common subset of formats is in general useful, and because we want to be able to add codecs to this set.
When compiled in debug mode, on construction it checks that the codecs are compatible.
This helps make sure that users don't accidentally add ambiguous codecs, and if we add a new default codec in the future, tests will fail on ambiguity.

Several fixes to the "SWMRList" example in experimental/hazptr.
Summary:
Fix a correctness bug in "SWMRList.h".
Thanks to Maged for the tip! The old code omitted setting a removed node's
"next" pointer to `nullptr`, which meant that if the writer removed node
A and then node B = A->next while the reader was looking at B, then the reader
might happily keep chasing pointers B->next, B->next->next,... without ever
noticing that it was now on a "dead branch" of the linked list.
(And then there's a bit of a trick: you really do have to remove the node
first and *then* set its "next" pointer to null, because if you do the null
assignment first, you'll truncate the list, which means that some readers
will see a truncated list and return the wrong answer. I've added comments
to try to explain this to future-me.)
Style nit: Avoid doing multiple atomic operations on the same line of code.
----
Modernize the parameter-passing conventions in SWMRList.h.
Pass `T`s by const reference, except in `add` where we're likely to want to
make a copy of the `T` anyway. In that case it would be more "STL-correct"
to supply two different overloads `add(T&&)` and `add(const T&)`, but this
is just an example so it makes sense to keep things simple.
----
Fix an undefined behavior in SWMRList example.
Searching an empty SWMRList<int> always invokes undefined behavior by
comparing an uninitialized `T elem` against `val` on the final line of
the `contains` function. Besides, this patch allows SWMRList to work
with `T`s that aren't default-constructible or even copy-constructible.

Folly Futures to Python Asyncio Futures Bridge
Summary:
folly/python/futures.h provides some helper functions for bridging folly::future to asyncio.Future.
folly/python/NotificationQueueExecutor.h is a Driveable executor that has a fileno() method that can be monitored using (select, epoll) to determine if the drive method should be called.
folly/python/executor.pyx is an implementation of a "driver" for the NotificationQueueExecutor from the python asyncio side. It tracks also keeps track of asyncio eventloops to Executor mappings.
the getExecutor() from folly/python/futures.h uses that mapping to return the correct executor for this python thread.

teach gtest how to pretty-print StringPiece values
Summary:
Even though an ostream operator<<() is defined for StringPiece, gtest doesn't
use it when printing StringPiece values in test failure messages. Because
StringPiece defines a nested iterator type gtest instead treats StringPiece as
a container, and prints each of its elements (characters) one-by-one. This is
fairly awkward to read.
This diff defines an explicit PrintTo() function for StringPiece in
folly/test/TestUtils.h. This makes gtest print StringPiece values nicely if
you include TestUtils.h in your test sources.
