Description

in KUC broadcast groups, the message delivery fails if a userland process terminates without closing its kuc channel properly.
This patch improves the behavior of KUC broadcast groups, to make it more adapted for HSM usage:
the message delivery is successful if at least 1 userland process is present in this group and receives the message successfully.
Only HSM copytools use KUC broadcast groups (no impact on changelog processing).
