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.

libziparchive-host is no longer necessary, and mixing libziparchive-host
and libziparchive can cause ODR violations.

* Use const reference type for parameters to avoid unnecessary copy.
* Suppress warning of not using faster overloaded string find function.

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.

Sometimes, the new pss is significantly less than the stable pss. Do
not fail if this case occurs.

When creating an UnwindMapLocal fails in the Build() function call,
the destructor for UnwindMap is called. Unfortunately, the map_cursor_
member variable has not been initialized, so the call to destroy it
winds up operating on garbage data.
Part of this is a result of a bad class hierarchy, so this refactors
the classes slightly, and properly initializes the map_cursor_ member
variable in the base class.

BacktraceOffline is the only code that uses libLLVM. Create
a new shared library, backtrace_offline.so, that references this
so that including libbacktrace.so doesn't wind up pulling in libLLVM.

The check_unreadble_elf_* tests only create a readable map. I changed
libunwind to disallow unwinding through non-executable maps, so make
the maps executable too.
