Evgeniy Stepanov 769d46f373 [sanitizer] Use system unwinder in signal handlers on Android. 
Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.

Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.

Evgeniy Stepanov 6db97e82a4 Add a copy of missing <ucontext.h> for Android and enable ASan SEGV handler. 
This change adds a copy of <ucontext.h> for Android found in google-breakpad
that is missing from the official NDK.
ASan SEGV handler is still disabled by default and can be enabled with
ASAN_OPTIONS=handle_segv.
