tm: fix t_check messing up replies branch

- when t_check was called twice for a reply (e.g. t_check_trans() in
  script in the main onreply_route and then internally in tm
  reply_received), the second call did return an invalid branch.
  Now the current branch is remembered along T so t_check will
  always return a valid branch.

- added T_branch, a new global variable that holds the current
  branch corresponding to T (is valid only if T is valid).

- set_t() takes now 2 parameters: a transaction and the current
  branch for the transaction. If the current branch does not make
  sense (e.g. for requests), T_BR_UNDEFINED must be used.
  This change ensures that every time T is set or changed, the
  current branch is also updated.

- more comments added
