[Devel] dialog functions

[Klaus Darilion]

Hi!

IMO the following functions would be quite useful for the dialog module. 
Is it much work to implement them?

dialog_exist(): checks if the transaction matches an existing dialog. 
Can be used as additional security check in loose_roote()

dialog_exist("$fu","$avp(count)"): returns the number of dialogs which 
have $fu in From: header or in To: header

dialog_from_exist("$fu","$avp(count)"): returns the number of dialogs 
which have $fu in From: header

dialog_to_exist("$avp(whatever)","$avp(count)"):  returns the number of 
dialogs which have $avp(whatever) URI in To: header

The last 3 functions can be used to count the number of concurrently 
calls of a user (of course this works only if dialog module also stores 
the URIs, not only the from/to tags.)

What do you think of that?

regards
klaus
