Fixed multiple UE EPC integration by resetting user->ueid=0;. Lots of logs in this commit, will remove later

Log the processor info like scheduler policy

And CPU affinity.
Also, use mlockall to keep our memory from being swapped out.

Dl_config_req and tx_req filtering allowed for either order

Also removed some unused functions we added.
Futhermore, removed our additions to the

To match emane.

Checked with:
```
ps ax -o pid,class,priority,comm |grep RR
```

Synchronized with emane.git's implementation of this code which
includes a unit test.

This commit also fixes two bugs in unqueue_matching and one inb
unqueue:

- unqueue_matching was returning the wrong pointer when
  there was no match

- both unqueue_matching and unqueue were not clearing the vacated
  queue entry after removing the item

```
$ ps -eL -o pid,lwp,class,priority,comm | grep -E softmodem|oai:'
 6500  6500 RR  -80 lte-softmodem

This change is to enable use of gprof which requires the process
call `exit` to write out the collected data.

The UE (lte-uesoftmodem) exits cleanly, but the eNB
(lte-softmodem) crashes as it tries to shut down...
