82dcb2beee [API] Remove deprecated WeakCallbackData and related functions. 
This removes:
- PersistentBase::SetWeak that takes WeakCallbackData.
  The embedders should use the version that takes WeakCallbackInfo.
- PersistentBase::SetPhantom.
  The embedders should SetWeak that takes WeakCallbackInfo.

Functions in DefaultPersistentValueMapTraits are changed to accept
WeakCallbackInfo instead of WeakCallbackData.

b605482600 Add RegisterExternallyReferencedObject to PersistenValueMap 
PersistentValueMap is used to hold per-world wrappers in the blink. Currently,
when we trace wrappers, we visit wrappers in all worlds via this PersistentValueMap. This cl introduces convenient (and faster) way of registering these external references.

60c1ad026d remove phantom naming from the api 
since the old style weakness is slated for removal, we might as well reuse the name to limit confusion.  additionally I simplified the callback type to a enum to either get internal field values or not

this should be a non-breaking change with the exception of PhantomPersistentValueMap, which is unused.

06086a90e0 Fix the "PersistentValueMap" memory leak reported here: 
http://build.chromium.org/p/client.v8/builders/V8%20Linux64%20ASAN

The bug:
The code assumed that a weak Persistent whose weak callback is being
called would still be weak. That isn't true since the persistent is
un-weakened by the garbage collector before calling the weak callback. [1]

Specifically, PersistentValueMap would funnel all 'remove' actions
through its Release method, which uses PersistentBase::ClearWeak to
obtain the callback data. [2] For 'removes' caused by the weak callback,
ClearWeak always returns a NULL-pointer since by that time the weak
persistent was already un-weakend. The result was a memory leak in
the test, since the code to delete the weak callback data would
delete NULL.

The fix:
I explicity call Traits::DisposeCallbackData from the weak callback
with the data obtained from the v8::WeakCallbackData. To avoid invalid
calls to DisposeCallbackData, I also check whether this instance is
(still) weak before calling it. (That check could easily be elided
if it's expensive, for the price of having two 'remove' code paths.)

Severety:
Probably low. At least in Chromium, noone uses the API in a way to
trigger this; only the test does.

ebe0c79594 Remove V8_INLINE from v8-util.h. 
(These have been causing compilation problems on some
platforms. For VS, V8_INLINE turns into 'force inline',
which will then cause a problem when the compiler won't
actually inline. Search for "C4714 warning" for details.)

6730ec8433 Amend PersistentValueMap: 
- Use the surrounding map (instead of Traits::Impl) for weak callback.
- Provide for a fast reference to a mapped value.
- Restructure Traits to accomondate for the first point above.

[Why?] As discussed, I proceeded to replace Impl with the map.
The problem I encountered with that version is that now the
Traits class depends on itself: The weak-related methods require the
map type in their signature. But the map type includes the Traits class
and hence the Traits class method signatures depend on the specific Traits class. That
makes them practically un-derivable: While you can derive a Traits class
from another one, since the compiler now expects methods with a different
signature. To accommodate, I pulled the dispose traits into the weak traits
class. I also removed the Impl*/MapType* parameter from the Dispose call,
since no implementation seems to need it.

99b115b120 Provide default traits for PersistentValueMap 
Re-try of issue 201643003. This caused linker errors on Win64, since the
linker insists on seeing the StrongMapTrait method implementations even
though they are never used. This will provide default implementations
