Summary: [Folly] Fix Build: IPv6: `SocketAddressTest.SetFromStrings` and `AsyncSocketTest.ConnectTimeout` failing
On IPv6-only machines, the `SocketAddressTest.SetFromStrings` example in `folly/test/SocketAddressTest.cpp` was failing because it tries to resolve `127.0.0.1` with `AI_ADDRCONFIG` set. Fix it by detecting which of IPv6 and IPv4 are enabled, and picking an appropriate loopback address.

Make EliasFanoReader and BitVectorReader API more consistent
Summary: This diff introduces a few breaking API changes to both EliasFanoReader and BitVectorReader in order to fix some inconsistencies:
- As initalized, `EliasFanoReader` and `BitVectorReader` held a value of `0`, thus if `0` is present in the list `skipTo(0)` would not update the position to `0`, as it happens with any other `skipTo(<first element>)`. This fixes `jumpTo` accordingly.
- `jump(i + 1)` would go at position `i`. Now `reader.jump(i)`'s postcondition is `reader.position() == i`.
- It is now illegal to retrieve `value()` from a reader in an out-of-bounds position (before-the-begin or past-the-end). Validity of a reader can be checked with `valid()`.

Summary: Not aligning `lambdaBuf_` can lead to unaligned reads, which can be a problem on some platforms.

Fix a bad bug in folly::ThreadLocal (incorrect using of pthread)
Summary: Fix incorrect using of pthread in folly::ThreadLocal.
The root of the trouble (see man pthread_key_create):
"At thread exit, if a key value has a non-NULL destructor pointer,
and the thread has a non-NULL value associated with that key,
the value of the key is set to NULL, and then the function pointed to is called
with the previously associated value as its sole argument."
At thread exit we need to recover the thread-specific threadEntry
otherwise the subsequent calls of getThreadEntry may recreate it
(what actually DOES happen in the test ThreadLocalPtr.CreateOnThreadExit)
and the newly created threadEntry will "leak". It will live longer than the corresponding
thread violating the internal invariant of StaticMeta and also it will break
the code of the method onThreadExit. In particular this bug causes the failure
of the test ThreadLocalPtr.CreateOnThreadExit on OSX.

Overload on dynamic object reference type.
Summary: There are a bunch of methods in `folly::dynamic` that return a
reference to a sub-object, e.g. `getString()`.
These methods are a bit unsafe because it allows you to write code with dangling
references when the `folly::dynamic` object is an rvalue:
auto& obj = parse_json(some_string).at("key");
However, the bigger win is that when we have an rvalue `folly::dynamic`, such as
returned by `getDefault(...)`, we can move the sub-object out:
auto obj = parse_json(some_string).at("key");
auto str = obj.getDefault("another-key", "").getString();
In the first line, the subobject is copied out when it could be safely moved out.
In the second line `getDefault(...)` copies the dynamic sub-object out, and then
`getString()` copies the string out, when the string could be moved.
Also in the case of `getDefault()` being called on a rvalue, we can move the
sub-object out.
