* core.c (memory_error): Reword error msg to mislead less.

Browse Source 
* mips-pinsn.c (print_insn_arg 'd'):  Print $ with reg name.

        * mipsread.c (read_mips_symtab, read_the_mips_symtab,
        parse_partial_symbols): Use newer BFD internals (external_filehdr
        and external_aouthdr), byte-swap the fields that we care about
        before using them, and make the file header data local to
        read_the_mips_symtab rather than global.
