tty-handler: use simpler open in non-blocking mode

Currently, we're opening the tty file descriptor in blocking mode, then
switching to non-blocking mode with fcntl(F_SETFL, F_NDELAY);

[and F_NDELAY == O_NDELAY == O_NONBLOCK ]

This change just opens with O_NONBLOCK instead.

To Build

Note: In addition to a toolchain and autoconf tools, this requires autotools-archive to be installed.

To build this project, run the following shell commands:

./bootstrap.sh
./configure ${CONFIGURE_FLAGS}
make

To fully clean the repository, run:

./bootstrap.sh clean

To Run Server

Running the server requires a serial port (e.g. /dev/ttyS0):

touch obmc-console.conf
./obmc-console-server --config obmc-console.conf ttyS0

To Connect Client

To connect to the server, simply run the client:

./obmc-console-client

To disconnect the client, use the standard ~. combination.
