Release v1.4.18: Release Testing Fixes (Windows) 

1. For the ASCII and Wide versions of types and functions, make sure
   the wolfSSHd is being consistent using them.
2. In SFTP, use WSOCKETCLOSE to close the socket. Use the correct type
   for the socket.
3. Add parens around part of a ternary operator check to clear up some
   ambiguous order of operations.
4. Add a variable initializer for a COORD structure.
5. Add parameter checks to the Base16_Decode function.
6. Fix a double-freed handle.
7. Clean up a bunch of build warnings.
