This reverts commit 5672da0fa5.
This appears to be blocking the Skia roll by causing failures in the blink layout tests on the canvas-lost-gpu-context.html test.

Adds the glStencilThenCover* nvpr methods to GrGLInterface and starts
using them. When drawing multible paths, this will make it so we only
have to send the index/transform data once. It will also allow the
driver to save time internally.
The glStencilThenCover* methods are a newer addition, so they aren't
available on every driver. In the event that they are not present, we
emulate them using the existing glStencil*/glCover* methods.

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.

Add OpenGL ES extension functions needed to support NV_path_rendering in OpenGL
ES.
The added glProgramPathFragmentInputGenNV call is defined in NV_path_rendering
revision 30, similar to following:
Append to the end of the "Shader Inputs" subsection of Section 3.12.2
"Shader Execution":
The command
void ProgramPathFragmentInputGenNV(uint program,
int location,
enum genMode,
int components,
const float *coeffs);
controls how a user-defined (non-built-in) fragment input of a
GLSL program object is computed for fragment shading operations that
occur as a result of CoverFillPathNV or CoverStrokePathNV.
/program/ names a GLSL program object. If /program/ has not been
successfully linked, the error INVALID_OPERATION is generated.
The given fragment input generation state is loaded into the fragment
input variable location identified by /location/. This location
is a value returned either by GetProgramResourceLocation with a
/programInterface/ of FRAGMENT_INPUT_NV and a given fragment shader
input variable name or by GetProgramResourceiv with FRAGMENT_INPUT_NV
for the /programInterface/ and LOCATION for the property for a given
fragment input resource index.
....
glProgramPathFragmentInputGenNV will be used instead of glPathTexGen,
because the latter depends on fixed function pipeline that is not
exposed in ES.
Also add glGetProgramResourceLocation from OpenGL 4.3 or
ARB_program_interface_query.
Also add FRAGMENT_INPUT define to be used with glGetProgramResourceLocation.
The added functions are not used yet, but they're needed when implementing
NV_path_rendering support for OpenGL ES. They can also be used on OpenGL.
Remove uncalled NV_path_rendering functions, so they do not cause confusion
or take space in the interface definition. The ones that are later used
can be re-added when needed.
Remove definitions NV_path_rendering that are for NV_path_rendering function
parameters that are not used. The ones that are later used
can be re-added when needed.

Use fixed function pipeline only when drawing paths. Previously FF
vertex shader was used when drawing normal geometry if path rendering
was enabled.
This is required to make Chromium integration easier. This way
fixed function vertex shading, including vertexshader-less programs,
need not be implemented in the Chromium command buffer.
Removes FF TexGen functionality, as it is not used anymore. Likewise
removes the fixedFunctionSupport GL capability flag.

Pass vertices to the fixed-function shaders in vertex buffer object
stored at attribute 0. This is specified in OpenGL Compatibility
Profile Section 10.8.2 (Transferring Vertices With Vertex Attribute
Zero).
This makes future integration to Chromium command buffer better, since
the command buffer already has code for vertex buffer objects but not
vertex arrays.
Delete unused function pointers related to fixed-function codepaths.

While it doesn't matter on Windows, mingw on case-sensitive OSes uses all lower case filenames for platform include files. I found the problem in SkCondVar.h from Mozilla checkout of skia sources, but the patch contains a fix for the whole skia tree.
