Allow BIO_s_file to open and sequentially access files larger than 2GB on

/* Following definition aliases fopen to fopen64 on above mentioned

 * platforms. This makes it possible to open and sequentially access

 * files larger than 2GB from 32-bit application. It does not allow to

 * traverse them beyond 2GB with fseek/ftell, but on the other hand *no*

 * 32-bit platform permits that, not with fseek/ftell. Not to mention

 * that breaking 2GB limit for seeking would require surgery to *our*

 * API. But sequential access suffices for practical cases when you

 * can run into large files, such as fingerprinting, so we can let API

 * alone. For reference, the list of 32-bit platforms which allow for

 * sequential access of large files without extra "magic" comprise *BSD,

 * Darwin, IRIX...
