cfd5b080af system/core: preparation to pull back interfaces from android/log.h
Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Correct liblog/README

Effectively a cleanup and controlled select revert of
'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Test: compile

2ebce7384b Flattenable: switch from assignment to memcpy().
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.

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.

23c857ebd6 Make RefBase more robust and debuggable
This prevents two different kinds of client errors from causing
undetected memory corruption, and helps with the detection of others:

1. We no longer deallocate objects when the weak count goes to zero
and there have been no strong references.  This otherwise causes
us to return a garbage object from a constructor if the constructor
allocates and deallocates a weak pointer to this. And we do know
that clients allocate such weak pointers in constructors and their
lifetime is hard to trace.

2. We abort if a RefBase object is explicitly destroyed while
the weak count is nonzero.  Otherwise a subsequent decrement
would cause a write to potentially reallocated memory.

3. We check counter values returned by atomic decrements for
plausibility, and fail immediately if they are not plausible.

We unconditionally log any cases in which 1 changes behavior
from before. We abort in cases in which 2 changes behavior, since
those reflect clear bugs.
In case 1, a log message now indicates a possible leak. We have
not seen such a message in practice.

The third point introduces a small amount of overhead into the
reference count decrement path. But this should be negligible
compared to the actual decrement cost.

Add a test for promote/attemptIncStrong that tries to check for
both (1) above and concurrent operation of attemptIncStrong.

Add some additional warnings and explanations to the RefBase
documentation.

9ba7192c1f Improve RefBase documentation, especially for clients.
Add basic interface documentation to RefBase.h.

Much, but not all, of this is cut-and-pasted from an email message
from Mathias Agopian. The rest is reconstructed from the code.

Delete some, now redundant, text from Refbase.cpp, and add a bit
more about the implementation strategy.

Some minor fixes to internal comments.
