A new patch for mate

- changed the default config file name to "" 
- avoid trying to confgure mate when the config filename is ""
- add filename and line to config errors, that way one can actually
find errors in config files
- teady up the config error strings ( made them uniform )
- fixed a crash when missing index AVPs (Name,For,On etc) in config AVPLS
- make sure we do not delete the config AVPs and AVPLs to avoid
references to unsubscribed strings been left arround
- fixed the len on LoALs 
- changed the way loal_from_file reports an error.
- matelib/sip.mate was missing the Name in a PduDef  (from Julien Leproust)
- matelib/h225_ras had a wrong field name (from Julien Leproust)

At this point mate is silent when it's not expressely configured by the user.
