* Native ES modules
This is a major refactor of internal compiler.
Before: JS and TS both were sent through the typescript compiler where
their imports were parsed and handled. Both compiled to AMD JS and
finally sent to V8
Now: JS is sent directly into V8. TS is sent through the typescript
compiler, but tsc generates ES modules now instead of AMD. This
generated JS is then dumped into V8.
This should much faster for pure JS code. It may improve TS compilation
speed.
In the future this allows us to separate TS out of the runtime heap and
into its own dedicated snapshot. This will result in a smaller runtime
heap, and thus should be faster.
Some tests were unfortunately disabled to ease landing this patch:
1. compiler_tests.ts which I intend to bring back in later commits.
2. Some text_encoding_test.ts tests which made the file invalid utf8.
See PR for a discussion.
Also worth noting that this is necessary to support WASM

This adds the ability to spawn additional Isolates from Rust and send
and receive messages from them. This is preliminary work to support
running the typescript compiler in a separate isolate and thus support
native ES modules. Ref #975.

This reverts commit e976b3e0414dc768624b77e431ee7f55b03b76a4.
There is nothing technically wrong with this commit, but it's adding
complexity to a big refactor (native ES modules #975). Since it's not
necessary and simply a philosophical preference, I will revert for now
and try to bring it back later.

This bring it inline with terminology used in V8

`Isolate::from_void_ptr` is renamed to `from_raw_ptr`, to keep
consistency with std libs.
It is changed to `unsafe` function, because it can't guarantee that the
input is valid. This guarantee should be provided by the caller.
Its return type is changed to `&Isolate`, because `&mut Isolate` type
requires that no other aliases co-exist in this period of time, this
does not seem true. So I changed most of the methods to accept shared
reference `&Isolate`. It is easier to reason about the correctness of
`unsafe` blocks. As long as these shared references are in the same
thread, these `unsafe` codes are probably correct.

The main purpose of this PR is to remove the `'static` lifetime bound in
type OpCreator =
fn(state: &Arc<IsolateState>, base: &msg::Base, data: &'static mut [u8])
-> Box<Op>;
The reason is simple: it is plain wrong, the `data` is actually not `'static`. It is created when the message is sent from C side, and will be recycled when the message is responded. It violates the definition of `'static` lifetime.
If someone save this pointer somewhere else, and reuse it later again, uninitialized memory could be accessed. This kind of memory unsafety does not happen yet because the logic is carefully organized in this project. Lifetime constraints are maintained by code convention. It could be more robust if we can express this constraint by Rust's type system.
Basic idea: tie buffer's lifetime to an object's lifetime, a.k.a, RAII. The type `deno_buf` is pretty suitable for this job.

Does not yet support streaming, only strings and TypedArrays for now.

Adds a general HttpHeader flatbuffer message for serializing requests
and responses.

Also Buffer.readFrom in fetch() to buffer response.

This is a workaroud. Once the issue is resolved in Rust side, we should
remove it.
