Evgeniy Stepanov 4286a9bd5a [asan] Change detection of allow_user_segv_handler on Android.

Alexander Potapenko 7f9be7120d [ASan] Fix the logic that decides whether we need to spawn a new llvm-symbolizer in asan_symbolize.py

Alexander Potapenko 7a0f81a9b7 [ASan] Allow the users of SymbolizationLoop to make use of the --dsym_hint option in llvm-symbolizer 
Let the users of SymbolizationLoop define a function that produces the list of .dSYM hints (possible path to the .dSYM bundle) for the given binary.
Because the hints can't be added to an existing llvm-symbolizer process, we spawn a new symbolizer process ones each time a new hint appears.
Those can only appear for binaries that we haven't seen before.

Evgeniy Stepanov 9e922e7d24 [sanitizer] Android build cleanup. 
* Detect Android toolchain target arch and set correct runtime library name.
* Merged a lot of Android and non-Android code paths.
* Android is only supported in standalone build of compiler-rt now.
* Linking lsan-common in ASan-Android (makes lsan annotations work).
* Relying on -fsanitize=address linker flag when building tests (again,
  unification with non-Android path).
* Runtime library moved from lib/asan to lib/linux.

Evgeniy Stepanov 3f11c0d79c [asan] Fix SELinux setup on Android-K. 
On pre-L devices SELinux is set up in such a way that zygote wrapper
has to be in system_file context, not zygote_exec.

* Allow user SEGV handler if Android-L-like setup is detected.
  Necessary for correctness.
* Change file context labels on the wrapper script to appease SELinux.

Alexey Samsonov 968a358974 [ASan] Add new options for asan_symbolize.py script. 
The patch adds new features in asan-symbolizer script which are helpful for using ASan on embedded systems:

1) add cross-compile prefix for binutils
2) define path to sysroot with sanitized binaries

Features are enabled by command line options.
The patch also extends command line interface with help option.

Evgeniy Stepanov 322e89c4e2 [asan] Install asan_device_setup to bin/ when targetting Android. 
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.
