a7bba921c4 Update comment in the API to explicitly state that the handle returned
from Context::New is persistent and has to be disposed at some point
in order to allow garbage collecting the context.

897f7dedc1 Allow to define accessors on objects.
Currently one can only define accessors on object templates.  This patch
allows to create accessors on the fly.

These accessors could control access to elements as well.  This element
support is somewhat rudimentary and may require future work (for example,
we probably don't want to convert index into a string.)

ab6055d85d Landing patch by tonyg@chromium.org:
Changing ScriptData API to serialize its internal representation to a
const char* array.

This decouples the API from the internal representation and avoids the need for
callers to serialize themselves.

As a side-effect, ScriptData::New() no longer assumes ownership of its input.
This shouldn't matter as typical usage patterns for the old API would have
required a copy prior to calling ScriptData::New().

f6a2ccf6b4 Provide debug event listener with access to the debuggee context. Also introduce new event listener setter that allows to set a callback that accepts single parameter encapsulating all debug event details so that additional information can later be passed to the listener without breaking compatibility with existing clients.

3d7ce8ac19 CPU profiler: add secure profiles by filtering out functions using security tokens.
As several pages can run in a single V8 instance, it is possible to
have functions from different security contexts intermixed in a single
CPU profile.  To avoid exposing function names from one page to
another, filtering is introduced.

The basic idea is that instead of capturing return addresses from
stack, we're now capturing JSFunction addresses (as we anyway work
only with JS stack frames.)  Each JSFunction can reach out for
context's security token. When providing a profile to a page, the
profile is filtered using the security token of caller page. Any
functions with different security tokens are filtered out (yes, we
only do fast path check for now) and their ticks are attributed to
their parents.

54f0a5b221 Expose debug context into the native code. This change is doing several things:
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.

2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.

3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

eb4d261e24 Remove the different length string types
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.

On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

b5a19c1036 Rework the way we handle the fact that the ARM simulator uses a
separate JS stack.

In exception handling, we need to be able to compare addresses into
the JavaScript portion of the stack with the address of a C++ handler
on the stack.  Since the stacks are separate on the simulator, we need
a JavaScript stack address corresponding to a C++ try catch handler in
order to perform valid address comparisons.

On the simulator, we now link the C++ try catch handlers indirectly
through the JS stack and use the JS stack indirection address for
comparisons.

      JS                    C++
                           
                           handler

                 \
                  \---->   handler
 [C++ address]   <------    next_


On actual hardware the C++ try catch handlers continue to be directly
linked.

fb2317b63b New snapshot framework. Doesn't work on ARM yet (code targets
are different).  Is able to deserialize the whole heap and run
some stuff.  Not available as the primary snapshot system yet.

46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

e0b8ab8815 - Add String::Concat(Handle<String> left, Handle<String> right) to the V8 API.
This is the first step to address http://crbug.com/23131 by creating
a series of V8 ConsStrings as more data arrives from the server.

1f8399bdda Partially revert r2761.
Do not create handles for values of internal fields---this operation is performance
critical and plain pointers are safe.

Appy the same approach to External wrapping and unwrapping.

Plus some minor refactorings.
