Instead of calling a separate function in the server for each attack
action, just send an instruction to the victim to perform the action.

Don't split the client output and print line-by-line, just print the
full buffer unmodified. This requires fewer steps and the lines will be
separated anyway.

The server should close the handle to the logging file on server exit.

The logging API should write to both the specified file handle and
stderr. This allows the init system (if there is one in use) to also
write messages to its internal buffer.

Remove a line in server.c that set the client socket descriptor as
non-blocking. Since the server is multithreaded we do not need
non-blocking I/O.

Implement a series of functions that facilitate remote control
connections, i.e. connections that control session information, allow
exfiltration of data, etc. from the command server.

Remove the functions doing I/O on socket operations. These functions are
designed for single-threaded applications or for non-blocking sockets;
neither of which mini-rat has.

Instead of printing to stdout, print to a file or socket descriptor.
This will allow remote control connections to be implemented relatively
easily.

Mark the socket in the worker function as non-blocking and run poll().
This should be done in order to prevent a slow loris attack on the C&C
