The way libunwind handles local unwinds is different from remote unwinds,
so create a new map object to handle the differences.
Add new test to verify the map data is being generated correctly.
Add new tests to check for leaks.
Refactor the BACK_LOGW code into a single header file.

- liblog android_logger_get_log_size and android_logger_get_readable_size

- logcat Add -P, -p and -G flags
- logd Add LogWhiteBlackList and configurable log size

With AArch64 the enumerations with values in the range
0x80000000 to 0x80000007 are being assigned to ssize_t
typed variables which are 64-bit rather than 32-bit, and
are being used in conditions where they are being checked
for being negative. This is not the case when ssize_t is
64-bit, so redefine this to INT32_MIN value.

Wrap the call in a if (0) when verbose logging is disabled
to provide compile time checking.
Also add a printf format attribute to the function to warn
if parameters are incorrect.

SocketClient:
* Replace sendDataLocked with sendDataLockedv which takes an iovec.
* Add a version of sendData, sendDatav, which takes an iovec.
* do not preserve iovec content through sendDatav
SocketListener:
* Add runOnEachSocket, which allows to to specify a SocketClientCommand to
run individually on each socket. This allows you to do broadcast-like
actions customized for each individual socket.
* Client safe list reference counting for sendBroadcast & runOnEach Socket

This includes removing the map_info.c source and replacing it with the
BacktraceMap class to handle all map related code.
Change all callers of libbacktrace map functionality.
Also modify the corkscrew thread code so that it doesn't need to build
the map twice (once in the corkscrew format and once in the libbacktrace
format).

This patch also introduces new 64-bit atomic functions for
LP64 platforms.
