The commit contains pua_usrloc modifications, which simplifies the publish and regisration
processes: in every REGISTER an implicit publish is built in. In this way, a device e.g.
do not need to send two individual request towards kamailio (REGISTER, PUBLISH), it can be
achieved in a single but extended REGISTER request.
Another small fix is that if the publication is expired (due to broken TCP e.g.), a
"closed" NOTIFY should be sent to the contacts.

What do you mean by "a single but extended REGISTER request"? Can you give an
example of such REGISTER request?

Normally, the REGISTER and PUBLISH are sent separately. In our solution, it is not needed,
we should send only a „single” REGISTER with some „publish info”. A custom SIP header
(PresenceInReg) is defined in REGISTER which contains the presence information. Here is an
example:
REGISTER sips:example.com:443 SIP/2.0
Via: SIP/2.0/TLS 192.168.1.100;branch=z9hG4bK-524287-1---ec449f7fc5b0af2a;rport
Max-Forwards: 70
PresenceInReg:
device;open;<status><state>online</state><message>normal</message></status>

So this is a custom extension of you, not a standard, right?
If yes, I suggest that you change the patch to export a new function with a new name where
the relevant values are given as parameter, without taking anything from the SIP request
inside the function, so it becomes generic of what the custom header name is and the
format of the header body.
Now you practically disable the rfc version with defines, so it is not going to work
anymore for that. The RFC requirements implementation must be always there.

Long time and no follow up. I am closing the pull request for now, because it replaces the
standard IETF RFC requirements with some custom approach. The item can be reopen if a
patch with suggestions made in comments above is provided.
