Nucleus Patch

1. Nucleus builds changed the source file names to have a wolfssh_
   prefix. Take that into account for misc.c.
2. Change CleanPath to add a delimiter to the input string.
3. Reorganize the WS_GETtime macros to clean up adding specific items
   for Nucleus.
4. Add some typecasting on some sizeof.
5. Some whitespace cleanup, and removing a redundant include.
