[SR-Dev] master updated

[Andrei Pelinescu-Onciul]

I've merged into master the following branches:

andrei/module_interface
andrei/mod_f_params
andrei/mod_register
daniel/pv
andrei/fixups

I have not merged yet:
andrei/dbk_lib
janakj/db

They have to be sorted out before: lib/sr_dbk taken from andrei/dbk_lib
 together with the history (contains entire kamailio db history), then
 renamed into lib/srdb1 and Jan changes applied, + lib/srdb2 from
  janakj/db.

There is also henning/trie, but I guess that could be merged much later
 (and I don't know if it's ready anyway).
