eal: simplify parameters of hotplug functions
All information about a device to probe can be grouped
in a common string, which is what we usually call devargs.

calling the EAL probe function.
And the syntax could evolve to be more complex and support
matching multiple devices in one string.
That's why the bus name and device name should be removed from

Instead of changing this function, a simpler one is added

When removing a device, we already know its rte_device handle
which can be directly passed as parameter of rte_eal_hotplug_remove().
If the rte_device is not known, it can be retrieved with the devargs,
by iterating in the device list (future RTE_DEV_FOREACH()).

event/sw: add unit test for unlinks in progress
This commit adds a unit test that checks the behaviour
of the unlinks_in_progress() function, ensuring that the
returned values are the number of unlinks requested,
until the scheduler runs and "acks" the requests, after
which the count should be zero again.

event/sw: implement unlinks in progress function
This commit adds a counter to each port, which counts the
number of unlinks that have been performed. When the scheduler
thread starts its scheduling routine, it "acks" all unlinks that
have been requested, and the application is gauranteed that no
more events will be scheduled to the port from the unlinked queue.

event: add function for reading unlink in progress
This commit introduces a new function in the eventdev API,
which allows applications to read the number of unlink requests
in progress on a particular port of an eventdev instance.
This information allows applications to verify when no more packets
from a particular queue (or any queue) will arrive at a port.
The application could decide to stop polling, or put the core into
a sleep state if it wishes, as it is ensured that no new packets
will arrive at a particular port anymore if all queues are unlinked.
