* 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>]`.
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.
Refs #298
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.
* The purpose of this change is to match the C++ API more closely.
* This patch also increases consistency between the 'extern "C"'
function definitions on the Rust side with those on the C++ side.
* The 'message' parameter (a v8::String) to the various error
constructors no longer needs to be mutable.
