f08d1d0ce1 Stop using SkTSwap.
Use std::swap instead. It does not appear that any external user
specializes SkTSwap, but some may still use it. This removes all use in
Skia so that SkTSwap can later be removed in a smaller CL. After that
the <utility> include can be removed from SkTypes.h.

12ee97c991 crash rather than overflow in SkTDArray
This adds explicit overflow checks to the two likeliest
places where non-buggy code could overflow SkTDArray.

We have an #ifdef'd out PathMeasure_explosion GM that
overflows before this CL and aborts with it.

23e4544e94 disallow negative setReserve() calls
We already assert that setCount()'s argument is non-negative.
This does the same for setReserve().

There was one call site I could find that was actually sometimes
passing negative values to setReserve(), guarded here.

80e1d56e19 implement SkTDArray with std::vector
It's always worth seeing if we can get away with replacing custom data
structures with ones from the standard library.  Our array-like types
are all good candidates to replace with std::vector, and it's especially
easy to start with SkTDArray.  Unlike the others, it has no preallocated
S-variant, which is tricky to make work with std::vector.

SkTDArray also has known integer overflow bugs, leading to out of range
writes.  It'd be _very_ nice to ditch it for a better standard vector.

I removed a bunch of unused or little-used methods, and updated a couple
call sites that used methods in unusual or dangerous ways.

I've had to tweak GrAAConvexTessellator and SkBaseShadowTessellator just
a touch to work within the constraints of an std::vector impl.  It's not
intended to be legal to write to the reserved-but-not-counted elements
of an SkTDArray, but you can get away with it in our old implementation.
This version now uses setCount() to actually reserve and count them, and
should have the same performance and use the same amount of memory.

The PathMeasure_explosion GM I added recently to reproduce this bug now
draws without triggering undefined behavior or ASAN errors, provided you
have ~40GB of RAM.

539ebb8f75 rm SkTDArray::{Deleter,release()}
These are unused, and would make it conceptually tricky to replace
with something like std::vector that does not have a .release() method.

a93a14a998 Convert NULL and 0 to nullptr.
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).

18300a3aa7 detach -> release
The C++ standard library uses the name "release" for the operation we call "detach".

Rewriting each "detach(" to "release(" brings us a step closer to using standard library types directly (e.g. std::unique_ptr instead of SkAutoTDelete).

This was a fairly blind transformation.  There may have been unintentional conversions in here, but it's probably for the best to have everything uniformly say "release".
