Summary: Implements real_sigaction() which it turns out is required for internal_sigaction() to bypass the libc interceptors. Without real_sigaction(), our internal_sigaction() calls during init happen to work due to the EsanDuringInit check in COMMON_INTERCEPTOR_ENTER (though even here it does not feel right for an "internal_" call to go through the interceptor). The real problem is when we call internal_sigaction() after we're initialized, which only happens on an unhandled SIGSEGV for which the app has no handler: then we'll spin in an infinite loop as our attempts to remove our own handler repeatedly fail. It's not easy to add a test for that, unfortunately.
