[svn] * src/configfile.h,src/configfile.c,docs/noffle.conf.5: Add noffle-user and noffle-group configs. * src/configfile.c,src/fetch.c,src/fetchlist.c,src/protocol.c, src/server.c: Replace strcpy() with Utl_cpyStr() where appropriate. See Debian bug 168128. * src/control.c,src/configfile.c,src/noffle.c: Replace [s]scanf("%s") with [s]scanf(MAXCHAR_FMT). * src/noffle.c: Log warning if noffle.conf is world readable. * src/noffle.c: Restrict most options to news admins; i.e. those who are root or news on running Noffle. * Makefile.in,acconfig.h,aclocal.m4,config.h.in,configure,configure.in, docs/Makefile.in,docs/noffle.conf.5,packages/Makefile.in, packages/redhat/Makefile.in,src/Makefile.am,src/Makefile.in, src/authenticate.c,src/authenticate.h,src/noffle.c,src/server.c: Add basic authentication using either Noffle-specific user file or authenticating via PAM (service 'noffle'). PAM authentication needs to run as root, so a Noffle server that needs PAM must be started by root. Helpful (?) error messages will be logged if not. Noffle will switch ruid and euid to 'news' (or whatever is configured) ASAP. * src/noffle.c: Add uid checking.
