o Add SILC Zip API, compression.
- o Unix socket support to Socket Stream API (local socket stream).
-
o file removing, chmod, rmmod, etc. chdir, rmdir, stat, etc. to

+ * The `callback' will be called when a client connects to the listener

+ *
+ * Clients can connect to the listener by calling the
+ * silc_local_net_connect.
+ *
+ * Returns NULL on error and set silc_errno. If `schedule' is NULL this
+ * will call silc_schedule_get_global to try to get global scheduler.
