wolfSSHd port to Windows

[JacobBarthelmeh]

What's Left:

• SCP on Windows
• Public key / x509 authentication (currently only testing with password auth)
• Proper management of security level / access of connection (right now the create process uses current process token with higher privileges rather than user token)
  • SHELL
  • SFTP
  • SCP
• Better handling of waiting for data with shell, now it uses a lot of processing power while looping on checking if there is data to read/write
• SFTP connection
• Password auth shell connection
• Initial build and wolfSSHD VS project
• Additional testing
  • Memory leak testing
  • CI build tie in
  • static analysis testing
