[Support for trace debugging: registers that were not collected.]
        * remote.c (remote_fetch_registers): accept 'xxxx' in the register
        packet, with the meaning "register value is not available".
        Set register_valid to -1, which will connote "no value available".
        * findvar.c (read_relative_register_raw_bytes): return failure if
        register_valid == -1.  (value_of_register): return failure if
        register_valid == -1.  (read_var_value): return error if
        value_of_register fails for a register variable.
        (value_from_register): return failure if register_valid == -1.
        * eval.c (evaluate_subexp_standard): return error if
        value_of_register fails for a register used in an expression.
        * infcmd.c (do_registers_info): display "value not available"
        for registers for which register_valid == -1.

        * tracepoint.c (set_raw_tracepoint): just save the filename as is
        from the symbol table, rather than trying to prepend the dir name.
        Also save the bfd section.  (tracepoints_info): use the section
        when looking up the function name.
        * tracepoint.h: add section field to tracepoint struct.
