Rewrite as a stand-alone snmpd agent.
* NEWS: Document new features. * configure.ac: Raise version number. * src/.gitignore: Update. * src/Makefile.am: Build as an agent. * src/main.c: New file. * src/modconf.c: Remove "varnish" prefix from the configuration directives. (varnish_mib_config_init): Use program name as the base for the configuration file name. (varnish_mib_config_help): New function. * src/modconf.h (progname, pid_file, pid_file_immutable): New externs. * src/varnish-mib.8: Rewrite. * src/varnish_mib.mib2c (varnish_snmp_init) (varnish_snmp_deinit): Remove. (post_config): Extern. Called from main().
