This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

Many tests and examples use drawText with
a guess of how long the text is in bytes,
or a call to strlen(). Add a helper to
SkCanvas to simplify these examples.
Add another helper for SkString.

gm.h includes sk_tool_utils.h but does not use it.
The bulk of this CL makes each gm that uses sk_tool_utils include it.
sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

This is step one:
- make SkXfermode useless to public clients
- everything they should need is in SkBlendMode.h
Step two:
- remove SkXfermode.h entirely (since skia core will already be using SkXfermodePriv.h)

Matches our naming convention for all other types - factories that
return sk_sp (or any type that intelligently manages its own
lifetime) are named Make.
Previous factories are still around, assuming
SK_SUPPORT_LEGACY_COLOR_SPACE_FACTORIES is defined. Enable that
define for Android, etc.

- Switch to portable typeface, to avoid per-platform diffs in the labels
- Stretch out the image slightly, to avoid overlap with larger font
- Fix several tests that were no longer matching ground-truth. We treat
SkColor as sRGB, so 0x7F is incorrect, for example. Several of the
XferMode tests had similar math errors now. Computed new values, and
verified that they work as expected.
- Removed a couple tests that were mixing color and alpha in funny ways

Dirty GL-generated mipmaps whenever an sRGB texture is used with a new
value for TEXTURE_SRGB_DECODE. Add a new test rectangle to the gamma GM
that tests that textures are correctly converted to linear before
filtering when generating mipmaps.
Added a new unit test that alternates how a texture is interpreted (sRGB
or not), to verify that we rebuild mipmaps when needed, and that we get
the correct results out in both modes.
This test originally failed on four of our bots producing incorrect mips
in three different ways. I'm not real surprised, but it looks like
we can't rely on glGenerateMipmap to do the right thing, in conjunction
with TEXTURE_SRGB_DECODE.
Instead, actually create mip-chains using a series of draw calls.
(My first attempt used glBlitFramebuffer, and that still had bugs on
several bots). This approach appears to work correctly on any device
that fully supports sRGB.
Because the mipmap draws are fairly destructive to state, I had to
hoist them out of bindTexture. That means adding a second pass over
the texture accesses in the processor, at the very beginning of flush.

Attempts to render 50% grey through many different techniques. Only the first one (black/white dither) is guaranteed to be correct. This serves as ground-truth for all the others (independent of whatever your display may or may not be doing when viewing the output of the GM).
Current tests:
- Texture bilerp
- Texture scale (ie mipmaps)
- Simple paint color
- Gradient
- A handful of Xfer modes
- 50% grey bitmaps, both linear and sRGB
- Bitmaps wrapped in shaders, which hits a different raster code path
TODO:
- Test coverage (rather than alpha)?
- Text, Blur, etc...?
Re-landing this without the blitter selection change, which may have caused a regression. Also updated the text color so it's legible against both black (SampleApp) and white (gold).
