fix segfault on input packets with invalid checksum

libtle_udp: prevent receive code-path to reference packets
that were already freed.

udpfwd: if input device doesn't support IPV4 checksum offload,
we need to recalculate IPV4 header checksum of the
reassembled packet.

fixes 3395610ea65d ("Initial commit of tldk code").
fixes 8efc4c11464f ("Change libtle_udp to use dring").

Change libtle_udp to use dring.

Right now didn't see any noticeable performance boost with these changes.
Though it allowed to get rid of using locks at UDP TX code-path
and simplify the code quite a lot.

initial tle_dring implementation

The Dynamic Ring (dring) is a implementation of unbounded FIFO queue,
that supports lockless bulk enqueue/dequeue for multiple producers/consumers.
Internally it contains producer/consumer head/tail indexes
(same as DPDK rte_ring), plus linked list of Dynamic Ring Blocks (drb)s.
Each drb contains some metadata plus array of pointers to queued objects.
It is a caller responsibility to provide sufficient number of drbs for
enqueue operation, and manage unused drbs returned by dequeue operation.
dring features:
- FIFO (First In First Out)
- Lockless implementation.
- Multi- or single-consumer dequeue.
- Multi- or single-producer enqueue.
- Bulk dequeue.
- Bulk enqueue.

In preparation for further project expansion.
