* Use function pointers for symbol lookup (currently for elf32 and elf64,

  could be expanded).  This also fixes the bug with mips elf64 symbols
  in current Qemu trunk.

* Use quicksort and binary search for symbol lookup.

* Remove unneeded entries from symbol table.  This reduced a typical table
  size (linux mips kernel) from 1764487 to 11656 entries.
