It's undefined behavior to pass null as src or dst to memcpy, even if len is 0.
This currently triggers -fsanitize=attribute-nonnull warnings, but also can
lead to very unexpected code generation with GCC.
sk_careful_memcpy() checks len first before calling memcpy(),
which prevents that weird undefined situation.
This allows me to mark all sanitizers as no-recover, i.e. make-the-bots-red fatal.

Replaces drawPathsFromRange with a more general drawPathBatch method.
While this still isn't perfect, it's a step in the right direction that
removes the need for path range draws to fit in a public API.

In the repro case the conic in question has a replicated control point at the end. These points end up being slightly different by the time they get to convert_noninflect_cubic_to_quads so the initial checks for a zero vector don't fire. The following checks, in the constrainWithinTangents path, do fire however leading to a premature termination of conversion to quads.

When using NVPR, sometimes paths must be stroked by Skia and then drawn
with fill using NVPR. In these cases, use the fill type and bounds of
the stroked path, not the original path.

If the stream can peek less than requested, peek that amount. Return
the number of bytes peeked.
This simplifies crrev.com/1472123002. For a stream that is smaller than
14 bytes, it can successfully peek, meaning the client will not need to
fall back to read() + rewind(), which may fail if the stream can peek
but not rewind.
This CL revives code from patch set 3 of crrev.com/1044953002, where I
initially introduced peek() (including tests).
Add a test for SkFrontBufferedStream that verifies that peeking does
not make rewind() fail (i.e. by reading past the internal buffer).

When checking whether a matrix was a pure scale, we subtracted
0x3f800000 from the diagonals; if the diagonal value was already
very negative, we'd underflow. Replace subtraction with XOR.
When dealing with repeating tiled bitmaps, when the bitmap was
very large, we'd multiply an offset by 65535, possibly causing
underflow. Throw in a cast to long (casting to unsigned also
silences the warning and wouldn't involve extension, but I can't
convince myself that it's correct).

We were doing (x+127)/255 = ((x+128) + (x+128)>>8)>>8 in three instructions:
1) x += 128
2) shift x right 8 bits
3) add x and x>>8 together, then shift right more 8 bits
Now do it as two instructions:
1) shift (x+128) right 8 bits
2) add x and (x+128)>>8 and 128 all together, then shift right 8 more bits
On ARM this will be a 5-10% speedup for SrcATop, DstATop, Xor, Multiply, Difference, HardLight, Darken, and Lighten xfermodes. When we have a mask (e.g. text), *all* xfermodes except Plus will get a similar boost.
This should mean now that (a*b).div255() is the same speed as a.approxMulDiv255(b) on both x86 and ARM, and of course it's perfect instead of approximate. So we should eliminate approxMulDiv255(), but I'll leave it to another CL, as it'll need Blink rebaselines.
This CL should not change GMs or Blink.

Because the convolution kernel is (currently) applied in device space,
there's no way to know which object-space pixels will be touched. So
return false from canComputeFastBounds().
The results from the matrixconvolution GM were actually wrong, since
they were showing edge differences on the clip boundaries, where they
should really only show on crop boundaries. I added a crop to the GM
to keep the results the same (which are useful to test the different
convolution tile modes).
While I was at it, SkImageFilter::affectsTransparentBlack() was
inapplicable on most things except color filters, and its use on
leaf nodes was confusing. So I removed it, and made
SkImageFilter::canComputeFastBounds() virtual instead.
