This adds __libc_fatal, cleans up the internal logging code a bit more, and switches suitable callers over to __libc_fatal. In addition to logging, __libc_fatal stashes the message somewhere that the debuggerd signal handler can find it before calling abort. In the debuggerd signal handler, we pass this address to debuggerd so that it can come back with ptrace to read the message and present it to the user.
