1. Merge some of the allocators into sk_malloc_flags by redefining a flag to mean zero-init
2. Add more private helpers to simplify our call-sites (and handle some overflow mul checks)
3. The 2-param helpers rely on the saturating SkSafeMath::Mul to pass max_size_t as the request,
which should always fail.

This is more consistent with our other SK_BUILD_FOR_... macros,
and less likely to collide with other preprocessor logic.
(Luckily, this was defined in public.bzl, so we can do this
all in one CL in the Skia repo.)

This introduces skstd::index_sequence and skstd::make_index_sequence so
that these can be used in C++11. These are mostly equivalent to their
std:: counterparts. This also introduces SkMakeArray<N, C>
which is constexpr and creates a std::array with N elements with each
element being initialized with the value of C(i) where i is the index of
the element.
These are then used to create inverse gamma table at compile time. This
avoids threading issues.

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).

We were just combing through possible changes that might have affected
the attached bug, this popped out as pretty obviously unsafe.
This doesn't explain the Chrome bug...
SkAutoTMalloc and SKAutoSTMalloc are separate types. :(
The new test fails and crashes before, passes after.

Ensures that ".get()" always returns null when a container is empty.
Also ensures consistent assert behavior for array counts.
There are still differences in that the malloc variants take a size_t
and the arrays take an int, and that SkAutoSTMalloc defaults to the
stack-allocated buffer wheras the other containers default to null.

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".

SkUtility.h and SkTLogic.h implement a number of type traits now
available through <type_traits> and <utility>. This removes SkUtility.h,
replacing it with <utility>, and moves a number of traits in
SkTLogic.h to use the std:: equivelents. This change only uses C++11
parts of the standard library; SkTLogic.h will continue to provide
C++14 and beyond for now in the skstd namespace.
The changes to SkTLogic.h are being done gradually so that safe changes
may be landed confidently, with more risky changes in the future.

This change regularizes Skia's type traits so that when <type_traits>
can finally be used the transition is easier. Various traits are
renamed to match <type_traits> and placed in the skstd namespace.
Current users of these traits are updated.

The motivation for this was to remove SK_OFFSETOF from SkTypes, but
this CL is mostly about cleaning up our use of offsetof generally.
SK_OFFSETOF is removed to SkTypes and added to the two places it is
actually used (for the non standard behavior of finding the offset of
fields in types which are not standard layout).
Older versions of gcc required POD for offsetof to be used without
warning. Newer versions require the more relaxed standard layout.
Now that we no longer build on older versions of gcc, remove the
old warning suppressions.
PODMatrix is renamed to AggregateMatrix. SkMatrix is already POD
(trivial and standard layout). The PODMatrix name implies that the
POD-ness is needed for the offsetof, but it is actually the aggregate
attribute which is needed for compile time constant initialization.
This makes it more obvious that this can be revisited after we can
rely on constexpr constructors.
This also adds skstd::declval since this allows removal of existing
awkward code which casts a constant to a pointer to find the size of
a field.

SkTemplates.h contains a number of Skia specific utilities which are
not designed for external use. In addition to reducing the external
support burden, this will allow Skia to freely refactor this file.
