Make the Sk GL context class an abstract base class Make the Sk GL context class, SkGLNativeContext, an abstract base class. Before, it depended on ifdefs to implement the platform dependent polymorphism. Move the logic to subclasses of the various platform implementations. This a step to enable Skia embedders to compile dm and bench_pictures. The concrete goal is to support running these test apps with Chromium command buffer. With this change, Chromium can implement its own version of SkGLNativeContext that uses command buffer, and host the implementation in its own repository. Implements the above by renaming the SkGLContextHelper to SkGLContext and removing the unneeded SkGLNativeContext. Also removes SkGLNativeContext::AutoRestoreContext functionality, it appeared to be unused: no use in Skia code, and no tests.

Refactor SkGLContext to be actually extendable Refactor SkGLContext to be actually extendable. Before, non-trivial subclass would need to destroy the GL connection upon running the destructor. However, the base class would run GL commands in its own destructor (with destroyed GL connection) Refactor so that SkGLContext subclass object creation is completely done by the factory function. If the factory function returns a non-NULL ptr, it means the context is usable. The destruction is done with the destructor instead of virtual function called upon destruction. Make the destructors not to call virtual functions, for clarity. Remove custom 1x1 FBO setup code from the base class. It appears not to be used anymore.

Some fixes around GrContext::abandonContext: Fix debug crash when GrResourceCache is destroyed after GrContext is abandoned while GrTextures are in the exlusive list. Notify debug GL context that GL resources are expected to remain undeleted when context is destroyed after being abandoned. Stop leaking program cache entries when context is abandoned.
