scroggo@google.com f1754ec691 Replace SkPicture(SkStream) constructors with a factory.
SkPicture:
Remove the constructors which take an SkStream as an argument. Rather
than having to check a variable for success, the factory will return
NULL on failure.
Add a protected function for determining if an SkStream is an SKP
to share code with SkTimedPicture.
In the factory, check for a NULL SkStream.
Use a default decoder (from BUG:
https://code.google.com/p/skia/issues/detail?id=1325)

SkDebuggerGUI:
Call SkPicture::CreateFromStream when necessary.
Write a factory for creating SkTimedPictures and use it.

Use the factory throughout tools.

Add include/lazy to utils and effects gyp include_dirs so SkPicture.h
can reference SkImageDecoder.h which references SkBitmapFactory.h (in
include/lazy).

Changes code Chromium uses, so this will require a temporary Skia
and then a change to Chromium to use the new Skia code.

TODO: Create a decoder that does nothing to be used by pinspect,
lua pictures, etc, and allow it to not assert in SkOrderedReadBuffer.
