Derek Bruening b584410b80 [sanitizer] Add strnlen to the common interceptors 
Summary:
Adds strnlen to the common interceptors, under the existing flag
intercept_strlen.

Removes the now-duplicate strnlen interceptor from asan and msan.
This adds strnlen to tsan, which previously did not intercept it.

Adds a new test of strnlen to the sanitizer_common test cases.

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.

Directory structure:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan runtime library.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between various sanitizers.

ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).

ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:

make check-asan
