[svn] * src/client.c,src/client.h,src/fetch.c,src/noffle.c,src/server.c: robustness - instead of retruning simple Passed/Failed statuses from connection functions, return an integer status instead. This allows Noffle to distinguish between a connection failure, an unrecoverable protocol error and a recoverable problem. As a concrete instance, Noffle will no longer abort the connection if a group is removed from the upstream server. Also beef up error detection a bit. * src/content.c: instead of overwriting the existing content file(s) when updating - which leaves a window where Noffle is vulnerable to failure which will leave the content file corrupted (yes, it happened to me), write a new content file and rename it over the old file only when it has been written and closed with no errors reported.

To build an RPM for version m.n release r, set Version to m.n and Release to r.
Then rename the noffle directory to noffle-m.n, and make a compressed tar
noffle-m.n.tar.gz.

Run 'rpm -ta noffle-m.n.tar.gz' to generate binary and source RPMs.
