crypto/o_fopen.c: alias fopen to fopen64. 



Originally fopen(3) was called from bio/bss_file.c, which performed the
aliasing. Then fopen(3) was moved to o_fopen.c, while "magic" definition
was left behind. It's still useful on 32-bit platforms, so pull it to
o_fopen.c.

/*

 * 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...
