assign OTRDATA TLVs

Following up on our quick chat at CTS/Valencia, I would like to assign official TLVs for the DATA_RESPONSE and DATA_REQUEST TLVs we have been using in otr4j included in ChatSecure. Here's a quote of the mailing list post:

  • https://lists.cypherpunks.ca/pipermail/otr-dev/2015-February/002314.html

We (Guardian Project/ChatSecure) are currently working on nailing down the final API of our DATA_RESPONSE and DATA_REQUEST TLVs for in-band data transfer. We have it implemented now in otr4j and OTRKit, its been integrated in ChatSecure-android for 6+ months, and now we are pushing forward getting this integrated into more apps.

We have been using the TLV numbers 100 and 101 to make sure that we don't conflict with anything that might be in the works. I think now is the time to make an official number so that new apps do not need to handle a migration from the temp numbers.

What do we need to officially claim TLV numbers in the OTR protocol? How about 9 and 10? Should I submit a patch to libotr? Once we get it nailed down, the OTRKit code can be ported to libotr, since OTRKit is really a wrapper of libotr.
