1. elfcopy: Add --redefine-syms <file> arguments …

   This commit makes elfcopy the only tool I'm aware of that will let you
   rename symbols in dynamic libraries. Other tools like objcopy will only
   perform renaming on the symbol table, but will not rename dynamic
   strings or recalculate the hashes/offsets that change as a result.
   
   This works by creating a redefinition table, and handing symbol (dynamic
   and otherwise) to the table's get_redefined_name function before adding
   that string to the out_* variables. The elf binary is then regenerated
   from the output data (containing the renamed strings) and a valid DSO is
   generated.
