The check converts the usage of null pointer constants (eg. NULL, 0) to
use the new C++11 nullptr keyword.

   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

9d6049a96f fix pathops bug 8380
Paths to intersect have two nearly coincident cubics. Where they
cross, the intersection error makes the curves start at slightly
different points. To sort the intersection, one curve is translated
to the start of the opposite point, moving it from one side to the
other, introducing a winding error.

The fix looks for that error in a very tiny range (enlarging that
range causes other tests that now pass to fail). This fix is very
fragile and points to the need for a better approach than sorting
angles to find winding values, as documented in the bug.

Also renamed some angle functions to show that they operate only
on lines and not general curves.

All tests pass with this fix:
./out/release/pathops_unittest -V -x
./out/debug/pathops_unittest -V -x

5de5233463 remove scaling from pathops
PathOps added a cheat some time ago to reduce
fuzzer bugs by scaling down very large paths,
with the hope that it would make the math more
sane.

This had the side-effect of causing small edges
to disappear altogether if the bounds is large
enough.

Removing the scaling causes a single regression to
one fuzz-generated bug. That path succeeeded with
scale by eliminating the troublesome tiny contour.

Eliminating the scale may fix the CCPR-related bug
discovered by Flutter, or at least uncover the next
bug.

I would expect more fuzzer bugs to appear with
this change; paths with large and small values will
no longer have the small values removed.

ea2a6323bc fix pathops unsortable angles
Pathops determines which edges are kept and discarded
by sorting intersections counterclockwise. An edge
may be unsortable if it is too close to a neighbor to
clearly be on its left or right.

If a pair of lines is unsortable, they are probably
nearly coincident, but just far enough apart to escape
the coincident test.

The current code correctly marks the lines as unsortable,
but returned a guess at the sorting order anyway. Instead,
preserve the unsorted-ness (unsorted mess?) and let
the decision of what to keep defer til later.

This triggered a couple of asserts that needed rewriting
or disabling, but fixes the bug in question and does not
regress the extended tests in debug or release.

Also, fix a debugging routine that bit-rotted.

1d314433ff fix line intersect divide by zero
Test filinmangust14 exposes two problems:
- finding top of contour can expose divide by zero
- joining partial contour results can add diagonal

The latter makes the test return the wrong result,
and has not been seen in other tests. The fix
is to join disconnected contours by only following
the contours provided as input. Working on that.

The former bug is more straight-forward; just
don't try to compute axis-aligned intersection
if the denominator is zero.

All existing tests prior to the new one work
with this change.

3a4a3215f5 fix ops for very close rects
Pathops sorts line intersections to determine which edges to keep.
If the intersections are very short, they may get discarded and the
adjacent edge is used instead.

If a pair of edges are 180 degrees apart, and an adjacent edge is
part of the sort, it is ambiguous whether it is inside or outside
the span. Add logic to look for this and evaluate the original data
rather than the adjacent edge.

In a separate CL, I'll add a specialization for rect/rect ops.

Skia code. However, there are places where GL and Vulkan want

use NULL directly, and possibly more uses in un-compiled

73e597d0ed keep integral rectangle intersections integral
A pair of coincident lines can generate multiple intersection
points. Path ops is more stable when the intersection T value
is used to recompute the intersection point, but this has
the side-effect of making integral edges intersect at non-integral
values.

While it's worthwhile to fix this, for the moment it is less
disruptive to only worry about keeping intersection values
integral if the original intersection point is integral in
both axes.

Also, fix some debugging code that bit-rotted.

7eb01e00b1 simplify bug
The path contains a cubic with a very tight curve.
Split the cubic into pieces so that the individual
curves are better behaved.

Use both inflections and max curvature to 
potentially split cubics. Since this may require
a bit of work, preflight to ignore cubics that
monotonically change in x and y.

Only one of the three tests referred to by the bug
below repro'd. Use path.dumpHex() instead of 
path.dump() to capture the crashing data.

a35ab3e6e0 fix fuzzers
Many old pathops-related fuzz failures have built up while
the codebase was under a state a flux. Now that the code
is stable, address these failures.

Most of the CL plumbs the debug global state to downstream
routines so that, if the data is not trusted (ala fuzzed)
the function can safely exit without asserting.
