SkTCast is functionally equivalent to reinterpret_cast.
The comment about SkTCast helping to avoid strict alising issues is not
true. Dereferencing a pointer cast to a pointer of an unrelated type is
always undefined, even if smuggled through a union like in SkTCast.
To really avoid aliasing issues, you need to make a union[1] of the two
value types, or better, memcpy between values. I've had to fix
MatrixText.cpp where switching to reinterpret_cast actually let Clang
notice and warn that we're exploiting undefined behavior, and
GrSwizzle.h and SkCamera.cpp caught by GCC.
I've switched SkTLList over to use SkAlignedSTStorage, which seems
to help convince some GCC versions that fObj is used in a sound way.
[1] The union punning trick is non-standard in C++, but GCC and MSVC
both explicitly support it. I believe Clang does not officially
explicitly support it, but probably does quietly for GCC compatibility.

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.)

Moves readFromMemory, writeToMemory to private section.
No sign that these are called from google3, android,
chromium, but function names are common enough that
it's hard to know for sure.
These are used inside templates internally and for
testing, so it is not quite as simple as adding alternate
entry points in SkMatrixPriv.

SkMatrix::mapHomogeneousPoints takes an array of SkScalar,
but expects essentially SkPoint3, so make it so.

sk_inv_determinant has a guard that the determinant can't get too big so this CL only checks if the determinant gets too small.

This change removes sk_stdint.h since it is only needed for vs2008 and earlier.
This change removes SK_MMAP_SUPPORT define since it is no longer used.
This change removes the stdio.h include from SkTypes.h since on many systems
this is a very large header, few Skia files actually use it, it is
available everywhere standard, and SkDebugf should be used instead.
After this change there is no need for external users to put Skia's
include/config into their own list of includes, saving the headache
of having two header files of the same name and sometimes getting the
wrong one depending on include order.
