48a6683 by Guy Harris (guy@xxxxxxxxxxxx):

    Use wtap_read_bytes() to skip over bytes when reading a record.
    
    Allow file_read() to take a null pointer as a buffer argument; a null
    argument means "do everything except copy the bytes from the file to the
    user buffer".  That means that wtap_read_bytes() and
    wtap_read_bytes_or_eof() also support a null pointer as a buffer
    argument.
    
    Use wtap_read_bytes() with a null buffer argument rather than
    file_skip() to skip forward over data.
    
    This fixes some places where files were mis-identified as ERF files, as
    the ERF open heuristics now get a short "read" error if they try to skip
    over more bytes than exist in the file.
