Reported by:	Andrei V. Lavreniyuk <andy.lavr@reactor-xg.kiev.ua>

r207343:

Don't assume that "resource" property is in metadata.

Reported by:	Mikolaj Golub <to.my.trociny@gmail.com>

r207345:

Use WEXITSTATUS() to obtain real exit code.

r207347:

Mark temporary issues as such.

r207348:

Restart worker thread only if the problem was temporary.
In case of persistent problem we don't want to loop forever.

r207371:

Fix a problem where hastd will stuck in recv(2) after sending request to
secondary, which died between send(2) and recv(2). Do it by adding timeout
to recv(2) for primary incoming and outgoing sockets and secondary outgoing
socket.

r207372:

- Check if the worker process was killed by signal and restart it.
- Improve logging.

r207390:

Default connection timeout is way too long. To make it shorter we have to
make socket non-blocking, connect() and if we get EINPROGRESS, we have to
wait using select(). Very complex, but I know no other way to define
connection timeout for a given socket.
