[svn] * src/util.c: Improve (correct) error detection when updating timestamp file. * src/content.h, src/content.c: Return Boolean success/fail from Cont_write. Also ensure cont.first isn't polluted in the event of a failed update. * src/client.c,src/control.c,src/fetch.c,src/noffle.c,src/post.c, src/pseudo.c: If Cont_write fails, don't do actions that need it to have worked. Typically, don't update first and last article numbers in group database. * src/server.c: If groupinfo.lastupdate is unreadable or corrupt, spot this and report it and give an explicit error when processing NNTP NEWGROUPS command.

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.
