More termios fixes. We need to currently make sure to include:

#include "lldb/Host/Config.h"

Or the LLDB_CONFIG_TERMIOS_SUPPORTED defined won't be set. I will fix all
of this Termios stuff later today by moving lldb/Core/TTYState.* into the 
host layer and then we conditionalize all of this inside TTYState.cpp and
then we get rid of LLDB_CONFIG_TERMIOS_SUPPORTED all together.

Typically, when we start to see too many "#if LLDB_CONFIG_XXXX" preprocessor
directives, this is a good indicator that something needs to be moved over to
the host layer. TTYState can be modified to do all of the things that many
areas of the code are currently doing, and it will avoid all of the 
preprocessor noise.
