binutils opcodes error messages

binutils opcodes error messages

This patch is aimed at making binutils/opcodes files comply with the
GNU coding standard regarding error messages, that is, they should
start with the program name followed by a colon, then a lower case
message.  Accomplished by calling opcodes_error_handler to output the
program name (and final '\n'), rather than calling fprintf.
