Hi,
not sure about the other questions but perhaps I can at least answer
this one:

When you use one of the two policies, the fragment that is not sent is
returned in the messagep pointer passed to otrl_message_sending. The
other fragments are sent using the inject_message callback you provided.

The OTRL_FRAGMENT_SEND_ALL_BUT_LAST is useful when you are calling
otrl_message_sending from some kind of a hook that expects you'll have
modified message to send at the end (i.e. the application itself handles
the last fragment). Not sure when OTRL_FRAGMENT_SEND_ALL_BUT_FIRST can
be useful.

Hope that helps,
Martin
