[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.
