The libbacktrace common flags don't need the flags from
LLVM_HOST_BUILD_MK, they are added directly to libbacktrace_offline.
The -fno-omit-frame-pointer is unnecessary, as we no longer import
flags only used to build LLVM into everything that depends on LLVM.
Removing -Wno-extern-c-compat doesn't cause any warnings.

Reapplies I61c49fb62fdeafb66db25b8f97621239b8fd6e75 after fixing

libbacktrace_offline was inheriting -Wno-unused-parameter from llvm's
makefiles. Fix an unused parameter warning when compiling for an
unsupported architecture, and return false since *value wasn't
written.

1. Read .ARM.exidx and .ARM.extab, provides these data to libunwind
through AccessMem.
2. In FindProcInfo, search .ARM.exidx for the idx entry of function
containing ip.
3. Add structures to store .ARM.exidx info in DebugFrameInfo, and
clean up the structure.
4. Add tests to test each unwind information (.eh_frame, .debug_frame,
.gnu_debugdata, .ARM.exidx) separately.

Bug: http://b/28866258
Remove dependency of backtrace_test on libLLVM. Also clean up
specification for libbacktrace_offline module. Since it is a static
library now, dependencies are only needed to automatically include
necessary headers.
Test: 32-bit and 64-bit backtrace_test passes on host and on Angler.

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'.

Modify BacktracePtrace::Read to use the process_vm_readv syscall
instead of doing multiple ptrace calls.
Test: Ran the backtrace unit tests on host and on x86_64 emulator.

Should use android/log.h instead of log/log.h as a good example
to all others. Adjust header order to comply with Android Coding
standards.

If the underlying local map changes, it's possible for multiple
threads to try and modify the map data associated with the UnwindLocalMap
object. Add a lock when generating the local map to avoid this problem.
In addition, add a read lock whenever any caller gets the maps iterator.
Updated all iterator callers to make this lock.

LOCAL_LDLIBS should only be used with -l flags for NDK and some host
libraries. Other uses should use LOCAL_SHARED_LIBRARIES.
LOCAL_LDFLAGS should not contain -l entries, they should be in
LOCAL_LDLIBS instead.
LOCAL_CFLAGS should not contain -I entries, those should use
LOCAL_C_INCLUDES instead.

As device may not have libbacktrace_offline shared library, simpleperf
no longer rely on it. So there is no reason to keep libbacktrace_offline
shared library.

Remove the logging of an error if a thread disappears before the unwind
can begin. This can happen, so allow the caller to determine if this
is really a problem worth logging.
