FlattenableUtils read() and write() currently use assignment to copy
bytes. However, by casting the void* buffer to type T, the compiler is
allowed to assume that buffer obeys the alignment requirements of T,
which is not necessarily the case during serialization. On some
architectures, we can get SIGBUS when this alignment is violated.
We don't want the users of these routines to have to worry about
alignment when packing structures, so use memcpy() instead which should
always be safe since the compiler won't assume any alignment for the
void* buffer.
On architectures that can handle unaligned direct read/write of type T,
the compiler should be smart enough to optimize this code back to a
direct read/write anyway, but architectures that can't handle it will
fall back to memcpy; this means that this change shouldn't have any
impact on current Android devices. See the linked bug for more details.
Bug: http://b/31671510
Test: libgui Sensor serialization no longer gives SIGBUS.
Test: libgui.so unchanged on Shamu before and after this CL.

android_get_control_socket has a warning from the implicit cast from
long to int. The warning was being hidden because cutils/sockets.h was
included with -isystem. Move android_get_control_socket to sockets.cpp,
since we don't want header only dependencies anyways, and fix the
warning with a range check and a static_cast.

system/core/include is included in the global include path using
-isystem, which hides all warnings. Fix warnings in libutils
headers in preparation for moving from -isystem to -I.
- Fix implicit cast from int64_t to long in Condition.h. Remove
the __LP64__ check and always compare against LONG_MAX before
casting.
- Fix implicit cast from size_t to ssize_t in KeyedVector.h
- Fix -Wshadow-field-in-constructor warnings in Looper.h and RefBase.h
- Move destructors for MessageHandler and LooperCallback to Looper.cpp
and ReferenceRenamer and VirtualLightRefBase to RefBase.cpp to prevent
vtables in every compilation unit.
- Declare template variables in Singleton.h
- Fix old-style casts in StrongPointer.h and TypeHelpers.h
- Use template metaprogramming in TypeHelpers.h to avoid warnings on
memmove on non-trivial types.
- Add an assignment operator to key_value_pair_t to complete
rule-of-three
- Use memcpy instead of dereferencing a reinterpret_casted pointer to
treat the bits of a float or double as int32_t or int64_t
- Escape unicode sequences inside doxygen comments between \code and
\endcode
- Remove WIN32 ZD definition in Compat.h, %zd works fine with mingw
- Fix WIN32 printf warnings in Filemap.cpp
- Initialize mNullValue with 0 in LruCache.h, some of the tests use a
non-pointer type for TValue.

Vector<T> objects are a dynamic type with a vtable, which is not

- Fix invalid doxygen syntax in graphics.h
- Use a pragma to hide a C99 extension warning on the flexible length
array in graphics.h
- Make static functions in radio.h static inline

system/core/include is included in the global include path using

system/core/include is included in the global include path using
-isystem, which hides all warnings. zlib.h is included through
system/core/include/ziparchive/zip_archive.h, which was hiding warnings
in it. Use a #pragma around the call to deflateInit2, it is a macro
that expands to an old-style cast, in preparation for moving from
-isystem to -I. Also move the ZipString constructor to zip_archive.cc
so it can assert on the length of the string parameter and fix an
implicit conversion from size_t to uint16_t.

The android_color_mode_t defines the color modes supported
by a display. A display can support multiple different
color modes.
sRGB mode and AdobeRGB are deliberately placed at 7 and 8
so that they match mode ID's used on prior devices.
