[esan] EfficiencySanitizer base runtime library Summary: Adds the initial version of a runtime library for the new EfficiencySanitizer ("esan") family of tools. The library includes: + Slowpath code via callouts from the compiler instrumentation for each memory access. + Registration of atexit() to call finalization code. + Runtime option flags controlled by the environment variable ESAN_OPTIONS. The common sanitizer flags are supported such as verbosity and log_path. + An initial simple test. Still TODO: common code for libc interceptors and shadow memory mapping, and tool-specific code for shadow state updating.

[esan] Add custom flag support Summary: Adds custom flag support to EfficiencySanitizer's runtime library. Adds an initial flag cache_line_size which will be used by multiple tools.

[esan] EfficiencySanitizer libc interceptors Summary: Adds libc interceptors to the runtime library for the new EfficiencySanitizer ("esan") family of tools. The interceptors cover the memory operations in most common library calls and will be shared among all esan tools.

esan_interface.cpp
Add working set base runtime library Summary: Adds the base runtime library for the working set tool. Adds slowpath code for updating the shadow memory. To be added in the future: + Scan memory and report the total size. + Take samples for intermediate values.

esan_interceptors.cpp
[esan] Add handling of large stack size rlimits Summary: Adds detection of large stack size rlimits (over 1 TB or unlimited), which results in an mmap location that our shadow mapping does not support. We re-exec the application in this situation. Adds a test of this behavior. Adds general detection of mmap regions outside of our app regions. In the future we want to try to adaptively handle these but for now we abort. Moves the existing Linux-specific mmap code into a platform-specific file where the new rlimit code lives.

cache_frag.cpp
[esan] Intercept and chain signal handlers Summary: In preparation for fault-based shadow memory iteration, we add support for our own signal handler by adding app signal handler interception as well as chaining for SIGSEGV. This is done in a simple manner: we do not honor the app's alternate stack nor any sigaction flags for SIGSEGV. Adds a new test of transparency in app signal handling.
