3b08a1f82c Added new GetHeapStatistics API entry and deprecated old one.
Simplified the HeapStatistics class a bit, following Uncle Bob's advice that
adding accessors to DTOs only satisfies some design fundamentalists, but serves
no other purpose. :-)

1ac3949a93 Removed deprecated functions from v8's external API.
Removed the following deprecated functions:

   * Object::GetPointerFromInternalField
   * Object::SetPointerInInternalField
   * External::Wrap
   * External::Unwrap
   * Context::GetData
   * Context::SetData

They have been deprecated in the 3.15 branch and are not used by Chrome anymore.
Furthermore, judging from bug reports and email threads, embedders like node.js
and others are already using 3.15, too. All removed API entries can be emulated
by a one-liner, so adapting should not be hard for anybody.

We want to introduce more deprecations soon, but to keep things simple and avoid
having old and not-so-old deprecations in v8.h, the 3.15 deprecations are now
removed.

In general, the strategy of keeping deprecated things for one stable release and
then removing them seems to be a good compromise between a maintenance nightmare
and annoying external embedders. :-)

4cd41edcd9 Add methods to allow resuming execution after calling TerminateExecution().
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::ResumeExecution() -- When execution is terminated via a call to
  V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

cec0745aa2 Introduce callback for resolving global object name while taking heap snapshot
Heap profiler currently gets "document" of global objects while taking snapshot (to later retrieve its "URL"). This is unsafe as there may be no current v8 context when the property is requested while corresponding property accessor may make some assumptions about the context stack during its invokation. Several crashes were reported due to this problem:
https://bugs.webkit.org/show_bug.cgi?id=103076
https://crbug.com/162121
https://crbug.com/132727

This patch adds a callback for resolving global object names and avoid the crashes.

f3807ca17b Heavy cleanup of the external pointer API.
Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.

External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.

Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.

Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned
pointers.

37759f4d64 Implement committed physical memory stats for Linux.
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

In WebKit, we have a small integer cache because calling v8::Integer::New is
slow. This patch adds a faster API for creating integers that requires the
caller to supply the v8::Isolate, saving us the work of looking up the isolate

9dc2c5b83d Add an API for enumerating persistent handles
This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.

ccc827a6f8 Allocate block-scoped global bindings to global context.
- The global object has a reference to the current global scope chain.
  Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
  var and function still live on the global object.
  (Lexical bindings are not reflected on the global object at all,
  but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
  the chain into account.

Exposes a new API; V8::SetFunctionEntryHook.
