[PATCH v5 1/9] rv: Add da_handle_start_run_event_ to per-task monitors

[Gabriele Monaco <gmonaco@redhat.com>]

The RV da_monitor API allows to start monitors in two ways:
da_handle_start_event_NAME and da_handle_start_run_event_NAME.
The former is used when the event is followed by the initial state of
the module, so we ignore the event but we know the monitor is in the
initial state and can start monitoring, the latter can be used if the
event can only occur in the initial state, so we do handle the event as
if the monitor was in the initial state.
This latter API is defined for implicit monitors but not per-task ones.

Define da_handle_start_run_event_NAME macro also for per-task monitors.
