The constants in enum v8::ExternalArrayType have been changed. The old
values are there for legacy reasons, but it's best to update anyway.

smalloc.alloc now accepts an optional third argument which allows
specifying the type of array that should be allocated. All available
types are now located on smalloc.Types.
* Moved the ToObject check out of smalloc::Alloc and into JS. Direct
usage of that method is for internal use only and so can bypass the
possible coercion.
* Same has been done with smalloc::SliceOnto.
* smalloc::CopyOnto will now throw if passed argument is not an object.
* Remove extra TargetFreeCallback function. There was a use for it when
it was working with a Local<T>, but that code has been removed making
the function superfluous.
* Numeric values passed to alloc were converted to int32, not uint32
before the range check, which allows wrap around on ToUint32. This
would cause massive malloc calls and v8 fatal errors.
* dispose would not check if value was an Object, causing segfault if a
Primitive was passed.
* kMaxLength was not enumerable.
It will be confusing if later on we add Buffer#dispose(), and smalloc is
its own cpp api anyways. So instead create a new require('smalloc') to
expose the previous Buffer.alloc/dispose methods, and expose copyOnto
and kMaxLength as well.
Other changes:
* Added documentation and additional tests.
* smalloc::CopyOnto has changed from using assert() to throwing errors
on bad argument values because it is not exposed to the user.
* Minor style fixes.
If the user knows the allocation is no longer needed then the memory can
be manually released.
Currently this will not ClearWeak the Persistent, so the callback will
still run.
If the user passed a ClearWeak callback, and then disposed the object,
the buffer callback argument will == NULL.
smalloc is a simple utility for quickly allocating external memory onto
js objects. This will be used to centralize how memory is managed in
node, and will become the backer for Buffers. So in the future crypto's
SlabBuffer, stream's SlabAllocator will be removed.
Note on the js API: because no arguments are optional the order of
arguments have been placed to match their cc counterparts as closely as
possible.
With -e or --eval, require() can load module using relative path.
node -e 'require("./foo")'
But it can't load module from node_modules directory.
node -e 'require("foo")'
