file descriptors per processes. The tool now increases the
fd limit as required.

By implementing a trivial strlcpy it's much easier to detect string
truncations and react to them. This also gives a noticeable speedup in
buffer handling (can be HUGE), since strlcpy() doesn't clear all the
buffer entry before writing data.

Converted all uses of strncpy() into strlcpy().

Also, we don't need to check for some null pointers, as there are no
malloc-like operations in the doAction loop.
