When a device is created with "CREATE" as action, new rings are
allocated for it, then it is a good practice to free them when the
rte_ethdev_dettach method is invoked by the application.
Rings are not freeded when "ATTACH" is used or when the device is
created by means of the rte_eth_from_rings function.

Add a one-parameter function to take an existing rte_ring and wrap it as
an ethdev, returning the port id of the new ethdev instance.

The ring ethdev creation function creates an ethdev, but does not
actually set it up for use. Even if it's just a single ring, the user
still needs to create a mempool, call rte_eth_dev_configure, then call
rx and tx setup functions before the ethdev can be used.
This patch changes things so that the ethdev is fully set up after the
call to create the ethdev. The above-mentionned functions can still be
called - as will be the case, for instance, if the NIC is created via
commandline parameters - but they no longer are essential.
The function now also sets rte_errno appropriately on error, so the
caller can get a better indication of why a call may have failed.

The rte_eth_from_rings API allowed the creation of an ethdev port at
runtime using rte_rings as the underlying storage. However, the return
value from this function was either 0 or -1, and these values were never
actually documented in the API documentation. Unfortunately, the programmers
guide doc examples for this API implied that the return value from this
function was the port id of the newly created ethdev.
Since this latter behaviour is more useful - and already implied by the
documentation, this patch changes the return 0 to "return
data->port_id". It also adds in doxygen comments for the function so it
can be correctly documented in the API reference.
