[sr-dev] disable_6xx_block

[Juha Heinanen]

inaki's message prompted me to ask if sr tm module has something
like k tm disable_6xx_block parameter:

1.3.18. disable_6xx_block (integer)

Tells how the 6xx replies should be internally handled: 

0 - the 6xx replies will block any further serial forking (adding new
branches). This is the RFC3261 behaviour.

1 - the 6xx replies will be handled as any other negative reply - serial
forking will be allowed. Logically, you need to break RFC3261 if you
want to do redirects to announcement and voicemail services.

i didn't find anything from tm readme.  if that kind of parameter does
not exist yet, i think it should be added before release.
