- The recent change to linklists.h broke the build on linux for some reason.

So, I have removed all of the uses of AST_LIST_HEAD_INIT and replaced them
   with the equivalent static initializations.
 - On passing, fix a memory leak in the unload_module() function of chan_agent.
   The agents list mutex was never destroyed, and the elements in the agents
   list were not freed.
