drop a previous event, are converted to a series of flags which will

PMDs that only do a specific type of scheduling cannot provide
CFG_ALL_TYPES, so the Eventdev infrastructure should not demand
that every PMD supports CFG_ALL_TYPES.
By not overriding the default configuration of the queue as
suggested by the PMD, the eventdev_common unit tests can pass
on all PMDs, regardless of their capabilities.
RTE_EVENT_QUEUE_CFG_DEFAULT is no longer used by the eventdev layer
it can be removed now. Applications should use CFG_ALL_TYPES
if they require enqueue of all types a queue, or specify which
type of queue they require.
The CFG_DEFAULT value is changed to CFG_ALL_TYPES in event/skeleton,
to not break the compile.
A capability flag is added that indicates if the underlying PMD
supports creating queues of ALL_TYPES.
