  BIO: avoid returning internal FILE * with UPLINK-enabled builds on Windows

On Windows with UPLINK enabled, BIO_get_fp() may return a FILE * pointer
incompatible with the C runtime.  Ensure that it returns NULL instead,
preventing undefined behavior in applications.  Update the documentation
to include the missing return type for BIO_[gs]et_fp() and remove
the mention that BIO_get_fp() never returns 0, as it does so now
when NULL fp is returned.

  apps: adjust stat usage to account for uplink

Call stat() instead of fstat() when the FILE pointer provided
by BIO_get_fp() is unavailable (as it may be the case in case of UPLINK
builds).
