The VC++ STL with 2015u2 now provides a complete std::is_function.
Also, Skia is no longer using skstd::is_function.

The 'element_type' typedef is to play nice with std::pointer_traits.
The full complement of operators and swap to match unique_ptr so that
sk_sp can be properly compared to nullptr and used with standard
containers.
Update to 'reset' so that calling 'unref' is the last operation.
This also adds tests for these changes, and sets the fPtr to nullptr
in debug for easier bug finding.

Found and tested in mingw Firefox build. There are two problems:
- GCC doesn't support __vectorcall calling convention, so its usage needs to be #ifdefed
- GetProcAddress returns FARPROC type (a function pointer) and GCC requires an explicit cast to void*

SkTLogic.h contains implemenetations of is_empty, is_class, decay,
decay_t, add_lvalue_reference, add_rvalue_reference, and
add_rvalue_reference_t. The declaration of is_class is only used by
is_empty. The current implementation of is_empty will not work
correctly with 'final'. The current implementation of
add_lvalue_reference does not support clarifications in c++17. No Skia
code is currently using decay, decay_t, add_rvalue_reference, and
add_rvalue_reference_t. In addition, there are no known issues with
any of these in ::std with any supported compiler.
The implementations of is_function and is_convertible are commented to
note why they are still present.

SkTLogic.h specifies a number of declarations now found in
<type_traits>. This removes some of these declarations from SkTLogic.h
in favor of the ::std versions. These declarations are fairly safe to
change as the implementations are striaght forward and no known stl
implementations are known to have issues with them.

This replaces an existing incomplete implementation. This also makes
it easier to update the current use in the future when switching to
<type_traits>.

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.

- use C++11 features ({} init, move constructors) to eliminate the need
for explicit constructors
- collapse RECORD0...RECORD8 into just one RECORD macro
- explicitly tag record types instead of using member detectors.
Removing member detectors makes this code significantly less fragile.
This exposes a few places where we didn't really think through what to do
with SkDrawable. I've marked them TODO for now.

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.

No API change, only removes unused macro.

include/views/SkOSWindow_Win.h includes it.
To move SkTHash.h to include/private, SkChecksum.h needs to go there too. To move SkChecksum.h to include/private, SkTLogic needs to go there too.
This adds a bunch of -Iinclude/private to tools.gyp I missed in the last CL.
No public API changes.

Some of this is transitive, like SkRecords.h used by SkMiniRecorder.h
used by (public) SkPictureRecorder.h.
