util.startup: Fix exiting on pidfile trouble
prosody.shutdown() relies on prosody.main_thread, which has not been set
yet at this point.
Doing a clean shutdown might actually be harmful in case it tears down
things set up by the conflicting Prosody, such as the very pidfile we
were looking at.
Thanks again SigmaTel71 for noticing
local data = {}

local lines = data[file];
if not lines then

for line in io.lines(file) do
lines[#lines+1] = line;
end
end
io.stderr:write(ev, " ", file, " ", li, " ", lines[li], "\n");
