Summary:
This splits `EDEN_BUG()` into three separate version. All three crash in
debug mode builds, but in release builds they behave differently:
- `EDEN_BUG()` throws an exception
- `EDEN_BUG_FUTURE(Type)` returns a `folly::Future<Type>` that has been
fulfilled with an exception.
- `EDEN_BUG_EXCEPTION()` returns a `folly::exception_wrapper`.
The main advantage of this is that this allows the compiler to detect that
`EDEN_BUG()` can never return. Previously `EDEN_BUG()` was used for all 3 of
these different cases, and its behavior depended on whether `toException()`
was ever called. As a result we could not easily get the compiler to identify
code paths where we know at compile time that it will never return.

Summary:
I frequently find myself forgetting how to make the compiler see that
non-moved-from EDEN_BUG's destructor is noreturn, so add a simple
throwException function to it.

Summary:
Promote the folly logging code out of the experimental subdirectory.
We have been using this for several months in a few projects and are pretty
happy with it so far.
After moving it out of the experimental/ subdirectory I plan to update
folly::Init() to automatically support configuring it via a `--logging` command
line flag (similar to the initialization it already does today for glog).

Summary:
Switch from glog to folly logging. Also derive from folly::ColdClass to
indicate that the `EdenBug` class is only ever created on unexpected code
paths.
