Reduce partial methods/classes and streamline API surface across target frameworks

* Make Extensions.DebugPrint(this IEnumerable<byte>) available on all
target frameworks.
* Moved the following extension methods from Extensions.<target
framework>.cs to Extensions.cs:
- IsNullOrWhiteSpace(this string)
- CanRead(this Socket)
- CanWrite(this Socket)
* Removed GetIPAddress(this string) from Extensions.cs, and use
DnsAbstraction.GetHostAddresses(string) instead.
* Make ForwardedPortRemote(uint boundPort, string host, uint port) and
ForwardedPortRemote(string boundHost, uint boundPort, string host, uint
port) constructors available on all target frameworks.
* Eliminated SendData(IChannelSession channel, string command) partial
method from ScpClient.cs.

* Make the following methods on SftpClient available on all target
frameworks:
- SynchronizeDirectories(string, string, string)
- BeginSynchronizeDirectories(string, string, string, AsyncCallback,
object)
- EndSynchronizeDirectories(IAsyncResult)
* Make DnsAbstraction.GetHostAddresses(string) available on all target
frameworks.
* Added SocketAbstraction class.
