Console API is now used for interactive tty mode. Thus ssh.exe client
can now pass each character to remote side as one types so that programs
like more works correctly. Control-c now will stop the remote program
instead of exiting the ssh.exe.
Fixes issues like cmd.exe shell not handling backspace, control-c.
Control-c is still a work in progress and will be fixed but backspace
processing works. This work when complete will make cmd.exe shell and
powershell work better for interactive users.
