socket-handler: Use a global backlog buffer instead of per-client

Currently, we keep a backlog buffer for each connected client. This is a
waste, as it's storing the same data, just at different offsets.

This change uses a global buffer for the client backlog, with each
client tracking its current position in this buffer. We just make this
fixed-size, rather than trying to dynamically allocate.

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.
