Integrate functions and parameters from kamailio sources.

This patch adds db_bind_api function from kamailio sources to the list
of exported functions. Also we call the mod_init function from kamailio
sources at the and of the mod_init function in pg_mod.c. To make this
possible I added a new header file and removed static from the mod_init
function declaration.
