- added $InputTCPServerAddtlFrameDelimiter config directive, which
  enabeles to specify an additional, non-standard message delimiter
  for processing plain tcp syslog. This is primarily a fix for the invalid
  framing used in Juniper's NetScreen products. Credit to forum user
  Arv for suggesting this solution.
- added $InputTCPServerInputName property, which enables a name to be
  specified that will be available during message processing in the
  inputname property. This is considered useful for logic that treats
  messages differently depending on which input received them.

Enables to use FQDNs in sender names where the legacy default

(but could also leave it under some other circumstances...)
Thanks to David Lang and speedfox for reporting this issue.

...tried to send a message to it. This behaviour is operator-configurable.
If enabled, a message was emitted each time. That way an attacker could
effectively fill the disk via this facility. The message is now
emitted only once in a minute (this currently is a hard-coded limit,
if someone comes up with a good reason to make it configurable, we
will probably do that).
