32342f032e Rebase and fix chromium
Combine texture provider and resource provider

Largely mechanical. Only three places that were calling createApprox
via texture provider (ie without flags), so that was simple.

6bd5284415 Remove SkAutoTUnref and SkAutoTDelete from public includes.
This also makes the required changed to src, tests, and tools. The few
public APIs modified by this change appear to be unused outside of Skia.

Removing these from the public API makes it easier to ensure users are
no longer using them.

This also updates GrGpu::wrapBackendXXX and the
::onWrapBackendXXX methods to clarify ownership.

d309e7aa0e This replaces the texture creation/caching functions on GrContext with a GrTextureProvider interface. The goal is to pass this narrowly focused object in places that currently take a GrContext but don't need and shouldn't use its other methods. It also has an extended private interface for interacting with non-texture resource types.

9ea53f93e7 Preprend Test to test function name generated by DEF_TEST() macro.
That way when declaring a test with DEF_TEST() macro, you don't have to
uniquify the test name because it might colide with the class it is
being testing.

For example, if you are testing SkBase64 and do:

DEF_TEST(SkBase64, reporter) {
}

That will generate an error because the macro will declare a function
named SkBase64 which colides with the type SkBase64.

By adding Test to the function name we avoid this problem.

Fixed the entries found with the following command line:

$ git grep "Test, r" | grep DEF

e2eac8b2fd Move macros from TestClassDef.h to Test.h
Motivation: those macros don't make any sense without the definitions
in Test.h.

4ee16bfaed Add a DEF_GPUTEST() macro.
This macro is similar to DEF_TEST() and simplifies the process of
setting up a GPU test.
