client: Create random pool to send data faster

This creates a pool of one thousand times the send buffer size which
will be used to send random data. This data might repeat itself, but
that is not a problem here because we only need to have more data than
the window of any compression algorithm.

server: Prevent useless stats printed when called too soon

Sometimes the timer event gets stuck in the queue and we would be called
multiple times in a row. To prevent printing any useless output, we just
ignore any calls that were too soon.

client+server: Process fewer epoll events in one go

This will allow us to terminate quicker because we will evaluate the
outer while loop more often which should be a rather cheap operation.

client: ALlow keepalive only mode

In this mode, the client won't send any data and only hold the
connections open.

client: Add some example for gathering random data

Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>

client: Give the user the choice whether to send random data or zero

This is useful when compression is being used on the link since random
data cannot be compressed, but the zeroes can.

client: Add timeout

This is a safety precausion which will terminate the client
automatically after a certain time just in case the network becomes
unresponsive.

client: Add a basic implementation

This will make the client connect to the server with one or more
connections and it will send data.

logging: Revert to log to console

Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>

server: Add basic implementation that accepts connections

This creates an asynchronous loop which listens for new connections
opening and which will close connections after the client has closed
them.

This will also read any data that is being received on the sockets and
discard it.
