Basic changes in configuration file

In the etc directory of SERi Ottendorf, you will find seri-basic.cfg and ser.cfg as two examples.

Please note the following changes:

• routes can now have names: route["test"]
• routes can return a value
• drop and exit are synonyms
• flags now have names setflag("cool")
• The use of selects @something has changed how read-only data can be accessed
• avpairs can now be directly accessed using $avpairname
• Fifo support was removed from core and "fifo=something" in the config file will produce an error. The fifo interface is replaced by ctl (implements a binary rpc interface, see modules/ctl/ctl.cfg - self documenting and utils/sercmd) or xmlrpc. Old backward compatible fifo support can be enabled eiher by configuring a ctl fifo or using the fifo module.
