It relies on flutter copy of clang distribution, same one that is used to build flutter/engine.
It addressed several deprecated warnings from clang compiler for functions like strdup, unlink, etc.
It allows few warnings still since they are triggered in third_party sources.

Message is a C++ type with a simple ownership model appropriate for
std::unique_ptr. This CL applies the following changes:
1. All uses of "new Message(...)" are replaced with
"Message::New(...)", which is effectively
"std::make_unique<Message>(...)". (The latter was only added in C++14,
but Dart still compiles in C++11 mode.)
2. All owning Message* are replaced with std::unique_ptr<Message>. The
notable exception is MessageQueue, which still uses raw Message*
internally to simplify the linked list handling.
3. All "delete message;" statements are removed.
4. Uses of "NULL" replaced with "nullptr" as necessary.

The problem with these changes was that closed ports still continue to receive
messages and as a result we start using dead peer objects.
Fixing that would require more intrusive changes into message handler implementation - so instead we are reverting the changes and restoring manual PORT -> PEER mapping.

This change add the ability to restart the vm through the service
protocol. All isolates are killed, and then the main isolate is
restarted cooperatively by the embedder.
This change also fixes the message handler to prevent it from
accidentally ignoring vm shutdown messages.
Previously, we would stop handling messages whenever we hit an error
(such as a compile error or an unhandled exception). This would leave
shutdown requests sitting the oob queue, neglected.
We now process *all* oob requests, up to the first shutdown request.
When we hit a shutdown request, we clear the oob queue and process no
more messages.
To make all of this work, we had to change the return value of
HandleMessage from bool to a new enum type, allowing the message
handler to distinguish *normal* error cases from the more rarified
shutdown and restart cases.

external length available. We now pass a length with all messages in
the vm and verify that there is no mismatch with the length from the
Snapshot.
Fixed a bug in the use of ApiMessageReader. We were always manually
adding Snapshot::kHeaderSize to the data, but neglecting to subtract
kHeaderSize from the message length.
Added FullSnapshotWriter and MessageWriter classes.

Instead of passing a size in bytes to the allocation function, we now
have a templatized Alloc function:
zone->Alloc<Type>(len)
This is better for security, as we can check for integer overflow in
the size computation before performing the allocation. Before, we
often failed to check this.

each isolate or native port had a dedicated thread.
Refactored the MessageHandler api...
- Added a Run function to allow a MessageHandler to run on a
ThreadPool. These functions take a start and end callback to allow for
isolate initialization and shutdown.
- Made the queue private to the MessageHandler and moved all message
processing code inside the MessageHandler (got rid of all of the
different flavors of RunLoop). This helps remove some code
duplication and hides the details of how messages are handled.
- Moved all locking and notification out of MessageQueue and moved it
up to MessageHandler. Moved OOB support out of MessageQueue and up
to MessageHandler. These changes make the MessageQueue much
simpler.
- Refactored native port and isolate MessageHandlers to share more code.
- Improved --trace_isolates output.
- Added tests for MessageHandler.
Refactored lib/isolate code...
- Use the new MessageHandler::Run api.
- Got rid of the LongJump stuff in RunIsolate. No longer needed.
- Use the new StartIsolateScope/SwitchIsolateScope to make the code
less verbose and less error-prone.
- Store top-level isolate errors in the sticky_error.
Added StartIsolateScope/SwitchIsolateScope classes.

The native port callback is now passed the message as a decodes
Dart_CMessage structure. The Dart_CMessage structure is allocated
in a zone and the callback receiving it should expect the
lifetime to be controlled by the caller.
Added support for zones which do not require a current
isolate. Changed the GrowableArray to support allocating in
aprovided zone instead of the zone for the current isolate.

Dart_NewNativePort creates a port associated with a C handler
function. When messages come in on this port, they are forwarded to
the C function for processing.
To support this, refactored PortMap so that it operates on a new
MessageHandler type instead of directly on Isolates.
For now, native ports have a dedicated single thread. Eventually we
will back native ports (and possibly Isolates as well) by a shared
thread pool.
