In order to move away from nested function use, some changes to the recently introduced

ast_channel_search_locked need to be made.  Specifically, the caller needs to be able to
pass arbitrary data which in turn is passed to the callback.  This patch addresses all
of the nested functions currently in asterisk trunk.
