Allows us to mitigate the impact of MAP_PRIVATE and copy on write by
calling android_lookupEventTag_len instead of android_lookupEventTag,
and delaying the copy on write impact to the later. We return a
string length in a supplied location along with the string pointer
with android_lookupEventTag_len(const EventTagMap* map, size_t* len,
int tag). The string is not guaranteed to be nul terminated. Since
android_lookupEventTag() called even once can cause the memory
impact, we will mark it as deprecated, but we currently have no
timeframe for removal since this is a very old interface.
Add an API for __android_log_is_loggable_len() that accepts the non
null terminated content and fixup callers that would gain because the
length is known prior to the call either in the compiler or at
runtime. Tackle transition to android_lookupEventTag_len() and
fixup callers.

Added liblog-unit-tests --gtest_filter=liblog.event_log_tags to
check for Shared_Clean: to not be 0 and Anonymous: to be 0 for
all processes referencing event-log-tags. Which can include multiple
references to /system/etc/event-log-tags and future possible refs to
/data/misc/logd/event-log-tags and /dev/event-log-tags. We want
failure messages to help point to errant code using the deprecated
interface.
This change saves 1/4MB of memory or more on a typical system.

Always used in combination with log/logger.h except in log_time.cpp,
and not used externally. As a result liblog has to support stl, a
small price to pay since goal is to convert liblog to C++ internally.

Cleanup.
Save the errno for the calls that fail, and reinstate them for
return. Drop fprintf stutter, one succinct line. Solve a memory
leak in close. Change android_lookupEventTag() to use an
unsigned int so that we can use the full range of uint32_t tags.
Make sure this file compiles clean in C++.

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.

Test: libgui Sensor serialization no longer gives SIGBUS.

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.

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

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.

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
