Reason for revert:
Need to somehow get access to encoders in chrome -- link error on the roll since SkImageEncoder is not built as part of chrome.

One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

This CL removes the uses of SkNEW that have resprouted since commit
385fe4d, and removes the macros entirely now that Android and Chromium
have been cleaned up to no longer depend on them.
A bunch of files implicitly depend on #include <new> from SkPostConfig.h
still though, so keep that for now. To be fixed in a followup CL.

Only public API removed.

Failing ImageNewShaderTest on both Android (Tegra3 GPU) and iOS bots.

This is done by having abstracted the BitmapShaderContext to take a BitmapProvider, instead of just a bitmap. This allows us to share all of that code between SkBitmap and SkImage, since both are valid providers.
It also means that we can simplify SkImage_Base to not need a virtual for onNewShader, since ALL images can uniformly be turned into a shader now.

Possible follow-up changes to consider
1. Roll SkImage_Raster and _Gpu into _Generator, where the generator (or cacherator) is backed by a pre-existing texture or raster.
2. Evolve SkImageUsageType into a verb requiring stretching, and have the caller (common code) digest the caps() and usage, so that subclasses are just told what to do (stretch or not)
3. Common code/utility to convert an unstretched texture into a stretch one (and cache it) if the generator can only make an unstretched one.

SkTemplates.h contains a number of Skia specific utilities which are
not designed for external use. In addition to reducing the external
support burden, this will allow Skia to freely refactor this file.

Prepare_rt_for_external_access() grabs the render target and then fires
access notifications.
But the notification handlers may trigger copy-on-write, causing the
returned render target to be stale (pointing at the detached snapshot).
We should grab the render target after firing notifications.

Does not try to cache calls to readPixels at the moment:
- not triggered by drawing
- not clear if we want to perform any pixel transformations (that readPixels allows) on the GPU or CPU
Can consider that another time.

To make this work, we tag their pixelrefs as temporarily immutable, allowing
ourselves to restore the pixels to mutability only when the image drops away.
This should allow us to wobble back and forth between writing to the Surface
and reading from the Image without a COW, with the Surface seeing mutable
pixels and the Image seeing immutable pixels.
The big idea is, Image doesn't need forever-immutable pixels, it just needs
pixels that are immutable as long as it's alive.

SkSurface_Raster snapshots do not lock their backing bitmaps when the
pixel ref is shared - they only lock on deep-copy.
But since for raster surfaces the pixels are always in memory, I think
it would be OK to also lock in the former case.
This allows for optimized (zero-copy) reads of raster surface snapshot
data.

Motivation:
- perf win for clients that overwrite the surface after a snapshot.
- may allow us to eliminate SkDeferredCanvas, as this was its primary advantage.
