[IRCServices] patch

[Mircea Damian]

Hello,

Here is a small patch against the latest version of ircservices (4.4.5)
which fixes two things:

- password encryption when compiled with gcc-2.7.2.x: the problem is that
  the buffers need to be initialized to 0 and by default they are full of
  garbage

- fix a possible smalloc(0) in sessions.c when it reads the exceptions
  which is possible to be an empty => nexceptions = 0 => smalloc(0);
  obviuous solution was to move smalloc after the check
