Colin Cross 17b5b82d64 Fix warnings in libutils headers
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.

Test: m -j native

John Reck d69089a742 Teach sp<> how to std::move
Arguably we should migrate to std::shared_ptr
but for now make std::vector<sp<>> a bit less
horrible

Mathias Agopian 7332f80db5 Fix sp<> conversion operator / constructor
some of the conversion operators were not using the proper
pointer type when calling incStrong/decStrong, usually it
has no bad consequences, but for some implementation
of the ref-counted object it could lead to recording the wrong
owner id.

Mathias Agopian 3e0f87541f Fix a wp<> bug where the owner ID would be wrong
this was introduced recently. we make sure to use
the correct owner id (the sp) instead of the wp.

Mathias Agopian b26ea8b30f Fix some issues with RefBase debugging.
First slipt sp<> out of RefBase into StrongPointer.h so it can be reused
more easily and to make it clear that it doesn't require RefBase.

Note: the rest of the change only affects the system when DEBUG_REFS is enabled.

The main problem we fix here is that the owner id associated with each
reference could get out of date when a sp<> or wp<> was moved, for
instance when they're used in a Vector< >.

We fix this issue by calling into RefBase::moveReferences from
a template specialization for sp<TYPE> and wp<TYPE> of the
type helpers. RefBase::moveReferences() has then a chance to
update the owner ids.

There is a little bit of trickery to implement this generically in
RefBase, where we need to use a templatized functor that can turn
a sp<TYPE>* casted to a void* into a RefBase*.

Introduced a new debug option DEBUG_REFS_FATAL_SANITY_CHECKS
currently set to 0 by default as there seem to be an issue
with sp<ANativeWindow> which trips the sanity checks.
