Bug#1077353: passing argument 1 of ‘ipc_set_pollfunc’ from incompatible pointer type

[Ferenc Wágner]

reassign 1077353 src:cluster-glue 1.0.12-23
affects 1077353 src:heartbeat
thanks

Both ipc_set_pollfunc() and cl_poll() are defined in libplumb2t64, so
this is an internal inconsistency of cluster-glue.
