Node codebase has evolved a lot in the more than 10 years of its
existence. As more features (and code) have been added, changed,
removed, it's sometimes hard to keep track of what gets used and what
not.
This commits attempts to clean some of those potentially left-over
headers using suggestions from include-what-you-use

Due to how the Environment class is used through the codebase,
there are a lot of includes referencing either env.h or env-inl.h.
This can cause that when any development touches those libraries,
a lot of files have to be recompiled.
This commit attempts to change those includes by forward declarations
when possible to mitigate the issue.

Previously, handles would not be closed when the current `Environment`
stopped, which is acceptable in a single-`Environment`-per-process
situation, but would otherwise create memory and file descriptor
leaks.
Also, introduce a generic way to close handles via the
`Environment::CloseHandle()` function, which automatically keeps
track of whether a close callback has been called yet or not.
Many thanks for Stephen Belanger for reviewing the original version of
this commit in the Ayo.js project.

- Instead of storing a pointer whose type refers to the specific
subclass of `BaseObject`, just store a `BaseObject*` directly.
This means in particular that one can cast to classes along
the way of the inheritance chain without issues, and that
`BaseObject*` no longer needs to be the first superclass
in the case of multiple inheritance.
In particular, this renders hack-y solutions to this problem (like
ddc19be6de1ba263d9c175b2760696e7b9918b25) obsolete and addresses
a `TODO` comment of mine.
- Move wrapping/unwrapping methods to the `BaseObject` class.
We use these almost exclusively for `BaseObject`s, and I hope
that this gives a better idea of how (and for what) these are used
in our code.
- Perform initialization/deinitialization of the internal field
in the `BaseObject*` constructor/destructor. This makes the code
a bit more obviously correct, avoids explicit calls for this
in subclass constructors, and in particular allows us to avoid
crash situations when we previously called `ClearWrap()`
during GC.
This also means that we enforce that the object passed to the
`BaseObject` constructor needs to have an internal field.
This is the only reason for the test change.
- Change the signature of `MakeWeak()` to not require a pointer
argument. Previously, this would always have been the same
as `this`, and no other value made sense. Also, the parameter
was something that I personally found somewhat confusing
when becoming familiar with Node’s code.
- Add a `TODO` comment that motivates switching to real inheritance
for the JS types we expose from the native side. This patch
brings us a lot closer to being able to do that.
- Some less significant drive-by cleanup.
Since we *effectively* already store the `BaseObject*` pointer
anyway since ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not
think that this is going to have any impact on diagnostic tooling.

This should help clarify what kind of resource a `StreamWrap`
represents.

Changes in the native code for the upcoming async_hooks module. These
have been separated to help with review and testing.
Changes include:
* Introduce an async id stack that tracks recursive calls into async
execution contexts. For performance reasons the id stack is held as a
double* and assigned to a Float64Array. If the stack grows too large
it is then placed in it's own stack and replaced with a new double*.
This should accommodate arbitrarily large stacks.
I'm not especially happy with the complexity involved with this async
id stack, but it's also the fastest and most full proof way of
handling it that I have found.
* Add helper functions in Environment and AsyncWrap to work with the
async id stack.
* Add AsyncWrap::Reset() to allow AsyncWrap instances that have been
placed in a resource pool, instead of being released, to be
reinitialized. AsyncWrap::AsyncWrap() also now uses Reset() for
initialization.
* AsyncWrap* parent no longer needs to be passed via the constructor.
* Introduce Environment::AsyncHooks class to contain the needed native
functionality. This includes the pointer to the async id stack, and
array of v8::Eternal<v8::String>'s that hold the names of all
providers, mechanisms for storing/retrieving the trigger id, etc.
* Introduce Environment::AsyncHooks::ExecScope as a way to track the
current id and trigger id of function execution via RAII.
* If the user passes --abort-on-uncaught-exception then instead of
throwing the application will print a stack trace and abort.

This commit attempts to address one of the items in
https://github.com/nodejs/node/issues/4641 which is related to
src/pipe_wrap.cc and src/tcp_wrap.cc.
Currently both pipe_wrap.cc and tcp_wrap.cc contain an AfterConnect
function that are almost identical. This commit extracts this function
into ConnectionWrap so that that both can share it.

85af1a6 was added (squashed into another commit) without running
through CI. Unfortunately, it breaks some of the CI builds, notably on
three of the CentOS setups.
Undoing that one small change to get builds green again.

One of the issues in #4641 concerns OnConnection in pipe_wrap and
tcp_wrap which are very similar with some minor difference in how
they are coded. This commit extracts OnConnection so both these
classes can share the same implementation.
