965d6f4d17 debuggerd: don't send SIGSTOP to crashing processes. 
This was actually nonfunctional until f5e8f0b, because it was using kill
after privileges were dropped. This doesn't seem necessary after the
changes to the sibling thread ptrace logic, though.

036ff2ce83 debuggerd: monitor the worker process for failure. 
Use sigtimedwait on SIGCHLD to watch our forked worker processes for
failure, so that we can guarantee that we always resume/kill the target
process if libunwind crashes.

c463ba45c4 Add error reporting mechanism for failing Unwind. 
Remove the logging of an error if a thread disappears before the unwind
can begin. This can happen, so allow the caller to determine if this
is really a problem worth logging.

7c89f9e955 debuggerd: fix several bugs caused by fork/setuid change. 
Previously, we weren't PTRACE_ATTACHing to all of the threads of a
process, and we were also trying to do it after forking and dropping
privileges. This patch ensures that all ptrace attaching/detaching
happens in one place, before forking/exiting respectively.
