[SR-Dev] git:master: tmx: doc updated

[Juha Heinanen]

daniel,

what should be done with t_load_contacts()/t_next_contacts()?  should
they go to module_k/tmx or modules/tm?  jan proposed to include them in
modules/tm, but i'm not sure what the current status is.

as we have discussed before, i don't consider the current implementation
of those functions a good one.  the reason is the branch structure,
which should be extended with information about status of branches
(used/unused).  it does not make sense to keep that in a separate avp.

also, in order to make things more simple to understand, i would also
like to get rid of distinction of request uri and appended branches like
was done in opensips.

perhaps these are already taken care of in sip-router?
