PATCH octets vs bytes for objdump

[Timothy Wall]

This patch implements non-octet-sized bytes functionality for objdump.

  * include/dis-asm.h (struct disassemble_info): Added octets_per_byte
field and initialize it to one (1)
  * opcodes/dis-buf.c (buffer_read_memory):  Use octets_per_byte field
to adjust target address bounds checking and calculate the appropriate
octet offset into data
  * binutils/objdump.c (dump_section_header, find_symbol_for_address,
show_line, disassemble_bytes, disassemble_data, dump_data): distinguish
between octets and bytes.
