The full process hierarchy isn't set up yet, but these changes
help prepare by doing two things:
- Add a -j option to enable supervisor-mode. Currently, just a single
"stem" process gets forked early on to be used as the basis for
further forking into real cluster nodes.
- Separates the parsing of command-line options from their consumption.
i.e. need to parse whether we're in -j supervisor-mode before
modifying any global state since that would taint the "stem" process.
The new intermediate structure containing the parsed options may
also serve as a way to pass configuration info from "stem" to its
descendent cluster node processes.
* origin/topic/jsiwek/improve_comm_loop:
Add a simple FD_Set wrapper/helper class.
Fix Pipe copy/assignment to make a copy of flags.
Fix possible abort on writing to a full pipe.
