SkBitmap.cpp:
When copyTo calls readPixels, only clone the genID if the resulting
SkPixelRef has the same dimensions as the original. This catches a
bug where copying an SkBitmap representing the subset of an SkPixelRef
(which implements onReadPixels) would result in the copy sharing the
genID. (Thanks to r6710, this case can only happen using setPixelRef,
so the updated GpuBitmapCopyTest checks for that.)
Move some unnecessary NULL checks to asserts.
When copyTo performs a memcpy, only clone the genID if the resulting
SkPixelRef has the same dimensions as the original. This catches a bug
where copying an extracted SkBitmap with the same width as its original
SkPixelRef would incorrectly have the same genID.
Add a comment and assert in deepCopyTo, when cloning the genID, since
that case correctly clones it.
BitmapCopyTest.cpp:
Pull redundant work out of the inner loop (setting up the source bitmaps
and testing extractSubset). Create a new inner loop for extractSubset, to
test copying the result to each different config.
Extract a subset that has the same width as the original, to catch the
bug mentioned above.
Remove the reporter assert which checks for the resulting rowbytes.
Add checks to ensure that copying the extracted subset changes the genID.
GpuBitmapCopyTest:
Create an SkBitmap that shares an existing SkPixelRef, but only represents
a subset. This is to test the first call to cloneGenID in SkBitmap::copyTo.
In this case, the genID should NOT be copied, since only a portion of the
SkPixelRef was copied.
Also test deepCopy on this subset.
TestIndividualCopy now takes a parameter stating whether the genID should
change in the copy. It also does a read back using the appropriate subset.
It no longer differentiates between copyTo and deepCopyTo, since that
distinction was only necessary for copying from/to configs other than 8888
(which are no longer being tested), where copyTo did a read back in 8888 and
then drew the result to the desired config (resulting in an imperfect copy).

This macro replaces:
SkString str;
str.printf("Foo test Expected %d got %d", x, y);
reporter->reportFailed(str);
with the shorter code:
REPORTF(reporter, ("Foo test Expected %d got %d", x, y));
The new form also appends __FILE__:__LINE__ to the message before calling reportFailed().

In SkBitmap::extractSubset, perform a deepCopy, if the pixelRef supports it.
Fixes a bug in the 'extractbitmap' gm, which attempts to draw a subset of a texture backed bitmap (if the canvas is really an SkGpuCanvas).
Also fix some bugs that happen when there is a pixel offset. These fixes get bypassed by the deepCopy, but a user can still set a pixel offset manually.
When copying GPU backed bitmap with a pixel offset, copy the offset.
If the new config is the same as the old, copy fRowBytes as well.
Add a function to SkBitmap.cpp (getUpperLeftFromOffset) to find the x,y coordinate to use when copying to a new config.
Fix a bug where readPixels copied to the correct desired config and we were setting the generation ID to match even though the desired config was not the same as the original config (caught by my new tests!).
Add some tests to verify the correct behavior.
