 libdl: Add symbol searching and loading from archives.

 - Load archive symbol tables to support searching of archives
   for symbols.
 - Search archive symbols and load the object file that contains
   the symbol.
 - Search the global and archives until all remaining unresolved symbols
   are not found. Group the loaded object files in the pending queue.
 - Run the object file and loaded dependents as a group before adding to
 the
   main object list.
 - Remove orphaned object files after references are removed.
