Merge branch 'move-connection-password' of git://arthur.barton.de/ngircd-alex

This patch series converts the statically allocated password buffer in the
CLIENT structure into a dynamically (and only when needed) allocated buffer
which is referenced by the CONNECTION structure.

This a) saves memory for clients not using passwords at all and b) allows
for "arbitrarily" long passwords.

By Brett Smith (5) and Alexander Barton (2).
