interceptors and dont-delete attributes.
Minor change to the behavior of eval: throw exception when calling
eval in a context for which the global has been detached. This
matches the behavior of both Firefox and Safari post navigation in the
browser.

When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.
Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.
Make the ComputeIntegerHash globally available.
Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

This will enable reading profiler log in Chrome. The current implementation of memory buffer is trivial (fixed size buffer, no memory recycling) but enough to start end-to-end DevTools Profiler implementation. Later it will be enhanced.

The object delivered to the debug message handler contains additional information on the current break handling the messages.
Clients which require just JSON message parsing can simply get the JSON using the GetJSON message on the message object to still have the previous behaviour.
NewMessageHangler(const v8::Debug::Message& message) {
v8::String::Value val(message.GetJSON());
OldMessageHandler(Vector<uint16_t>(const_cast<uint16_t*>(*val), val.length()));
}
Refactored some of the debugger code to use internal handles instead of API handles. Also changed Object to JSObject is some places.
The access to the active context when the break occurred is still not implemented. I will add this in a new CL, as this one is quite big already.

The debug message thread was introduced to make it possible to have the message handler callback be called from a different thread than the thread running V8 where the debug event occoured, but it never had any practical use, and prevents providing information to the message handler which is only available from the V8 thread.
In the future any thread decoupling will have do be done by the embedder.
This also removes the queue used for outbound messages.
Renamed the class Message to CommandMessage as it is only used for debugger commands from the client. Related message queue classes has also been renamed.

The message handler function set through the debugger API is normally called in a different thread than the V8 thread where execution is stopped due to debugger event. This change adds an option to the API for specifying that the message handler should be called directly from the V8 thread. For an application like Chrome where thread dispatching is already in place this makes more sense.
Add an option to the message handler debugger API to process messages in the thread where V8 is running instead of posting it to a queue for processing on a additional thread.

- String traversal test data (now in a zone)
- Debug message thread (now joined on exit)
- Threading test threads (now joined on exit)
- Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8. Good times.

Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.
This has the side effect that function break points are not converted into script break points for named scripts.
Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.

The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger. The messages containing the JSON protocol has a RFC-822 like header with a Content-Length field and with the body containing the JSON in UTF-8 encoding.
The D8 shell has option --debugger-agent to start the debugger agent.

Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.
Using the uint16_t array to pass a void* is a temporary hack.

Moved the registrered debug event listener from the context to a global handle in the Debugger class. Storing it in the context did not make much sense.
Changed a lot of tests to handle the API change.

through the API. This allows us to verify state on entry through the API.
In this change verification in the API entry is checking that the current
thread holds the V8 lock when a HandleScope is instantiated if a v8::Locker
has ever been used by the V8 instance.

The main goal was to improve O(n^2) behavior when there are many object groups. The old API required the grouping to be done on the v8 side, along with a linear search. The new interface requires the caller to do the grouping, passing V8 entire groups at a time. This removes the group id concept on the v8 side.
- Changed AddObjectToGroup to AddObjectGroup.
- Removed the group id concept from the V8 side.
- Remove a static constructor while I'm here, lazily initialize
the object groups list.
- Cleaned up return by non-const references to return pointers.
