* objdump.c: Remove unnecessary prototypes.

	(disassemble_bytes): Add rel_offset parameter.  Simplify reloc skipping
	code, and print relocs when dump_dynamic_reloc_info.
	(disassemble_data): Read and handle dynamic relocs.  Correct reloc
	skip code.  Formatting.
	(dump_bfd): Don't dump dynamic relocs when disassembling.
