This keeps all FILE* handling on the OpenSSL side of the DLL boundary avoiding crashes on Windows while removing the need for libssh2 to read the private key file into memory. This is now done by OpenSSL which is likely to do a better job of it.
the recent commits converted the tabs to 4 spaces, which matched the
initial indent size. Other commits converted the tabs to 8 spaces, this
didn't match.
All the code has been converted to 4 space indents. No changes to line
lengths or actual code was performed. This is in preperation to my up
coming non-blocking work so my commits should only be code changes and
line lengths in the code I am working on.
