Christian Brauner (Amutable) b092062cb6 exec: introduce struct task_exec_state ...

Introduce struct task_exec_state, a per-task RCU-protected structure
that holds the dumpable mode and the user namespace and stays attached
to the task for its full lifetime.

task_exec_state_rcu() is the canonical reader: asserts RCU or
task_lock is held, WARNs on a NULL state, returns the
rcu_dereference()'d pointer.
