RFC introduce new string output plugin

This patch introduces a new string output plugin. The output string can be specified by "form" in config file. Format is consists of:

key: struct ulogd_key name enclosed by <>, e.g. <orig.ip.saddr.str>
group: enclosed by () and separated by |, pick first one if exists.
(<orig.l4.dport>|<icmp.type>|unknown) means
pick orig.l4.dport value if exist, or icmp.type value. if both of them do not exist, select "unknown" string.
+: add two key value if it can be
anything else: as is

meta character <>()|+\ needs to be escaped by \. Sink can be specified by "dest" like URI syntax, proto://host:port, proto can be either file, tcp and udp, e.g. dest="tcp://192.168.1.1:8125" for statsite. host is filename in case of proto is file or stdout if dest is "file://"

'.' and ':' in ip address format can be changed by specifying "addrsep" for use of graphite and statsd.
