    [gdb] Fix regoff_t incompatibility
    
    I did an experiment with importing the regex module in gnulib, and trying to
    build gdb.
    
    The first problem I ran into was that:
    - regoff_t was defined as long int, and
    - the address of a regoff_t variable i in ui_file_style::parse was passed
      as int * to function extended_color.
    
    Fix this by changing the types of some function parameters of functions
    read_semi_number and extended_color from int * to regoff_t *.
    
    Tested on x86_64-linux.
