ipc: recompute msgmni on ipc namespace creation/removal
Introduce a notification mechanism that aims at recomputing msgmni each time
an ipc namespace is created or removed.
The ipc namespace notifier chain already defined for memory hotplug management
is used for that purpose too.
Each time a new ipc namespace is allocated or an existing ipc namespace is
removed, the ipcns notifier chain is notified. The callback routine for each
registered ipc namespace is then activated in order to recompute msgmni for
that namespace.
