* Add `SharedPtr` as a nullable sibling to `SharedRef`.
* Add `Borrow`, `AsRef` and `AsMut` implementations as appropriate.
* `SharedRef<T>` now derefs to `T` rather than to `UnsafeCell<T>`.
* `array_buffer::BackingStore` now derefs to `[Cell<u8>]`.
In v8.h, not all heap object classes actually derive from `v8::Data`,
but this seems to be a mistake, because this hierarchy does definitely
exists in V8's internal source code.
The file naming in the current src/inspector/ directory is inconsistent and difficult to
navigate. It will be simpler if we just put them all in one place since they're rather
interconnected.
This doesn't really follow the current V8 API (it's pretty close to how
V8 used to be back in 2012 though.) However:
1. The C++ API is very C++-y and doesn't carry over well to Rust, and
2. It addresses the immediate need of being able to take heap snapshots.

This function acquires a mutex lock which, prior to this patch, would be
unlocked _after_ releasing the IsolateAnnex memory allocation where the
mutex was stored.
The `get_current_context()` and `get_entered_or_microtask_context()`
methods now return `Option<Local<Context>>` to reflect that an isolate
may not have entered any context.
They're also moved from `Isolate` to `struct Entered` because it turns
out that the underlying V8 API calls actually create new local handles,
hence they should only be used inside an active HandleScope.
The `InContext` trait has been removed.
A test exercising `ContextScope` and the `get_*_context()` methods
mentioned above was added.
Closes: #248.
This patch clarifies that v8::Isolate is a single threaded creature,
which can only be accessed from other threads in special circumstances.
To ensure optimal operation in Deno, we remove v8::Locker, which ought
to be unnecessary when a thread is dedicated to each Isolate and the
Isolates never move between threads.
There are valid use-cases for v8::Locker, and we hope to address them in
future versions of rusty_v8.

* Rename `Object::new2()` to `Object::with_prototype_and_properties()`.
* Make `Object::with_prototype_and_properties()` take a slice of keys
and a slice of values as arguments, instead of using
`Vec<v8::Local<v8::Name>>` and `Vec<v8::Local<v8::Value>>>`.
* Remove type `MaybeBool` from the public interface. These methods now
return `Option<bool>` instead.
* Fix parameter type mismatches between Rust and C++ APIs.
