Move some gpu headers from public include to src dir

[bsalomon, 2011-08-16 12:16:58]

I dunno what's with upload.py but I've moved the headers to src not just deleted
them from include.

svn stat:
X       third_party/externals/gyp
D       gpu/include/GrVertexBuffer.h
D       gpu/include/GrInOrderDrawBuffer.h
D       gpu/include/GrGeometryBuffer.h
D       gpu/include/GrIndexBuffer.h
D       gpu/include/GrGpu.h
A  +    gpu/src/GrInOrderDrawBuffer.h
A  +    gpu/src/GrGeometryBuffer.h
A  +    gpu/src/GrVertexBuffer.h
A  +    gpu/src/GrIndexBuffer.h
A  +    gpu/src/GrGpu.h
M       gyp/gpu.gyp

Assuming it's just a literal move, LGTM.

Closed with r2119 and r2120. (xcode's include path rules masked the fact that
SkGrTexturePixelRef.h was pulling GrGpu.g when it only needed GrTexture.h and
GrRenderTarget.h. Thus r2119 cause a build break fixed in r2120).
