Summary:
Adds interception of sigprocmask and pthread_sigmask to esan so that the
working set tool can prevent SIGSEGV from being blocked. A blocked SIGSEGV
results in crashes due to our lazy shadow page allocation scheme.
Adds new sanitizer helper functions internal_sigemptyset and
internal_sigismember.
Adds a test to workingset-signal-posix.cpp.

Summary:
Adds iteration of all application memory in an efficient manner using
shadow faults. Shadow memory starts out inaccessible and we mark it
writable one page at a time on each fault when the instrumentation touches
it. This allows iteration over just the mapped shadow memory, saving
significant time.
Adds a process-end iteration and pretty-printing of the final result.
Adds a new test and updates the existing tests.

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.
