Improvements to CC modules:

1) Add four new points that allow you to get more information
   to cc algo's
2) Fix the case where user changes module on a existing TCB, in
   such a case, the initialization module needs to be called on all nets.
3) Move htcp_cc structure to a union that other modules can use.
4) Add 5th point for get/set socket options for cc_module specific options
