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.
