examples/ipsec-secgw: support fallback session

Inline processing is limited to a specified subset of traffic. It is
often unable to handle more complicated situations, such as fragmented
traffic. When using inline processing such traffic is dropped.

Introduce fallback session for inline crypto processing allowing
handling packets that normally would be dropped. A fallback session is
configured by adding 'fallback' keyword with 'lookaside-none' parameter
to an SA configuration. Only 'inline-crypto-offload" as a primary
session and 'lookaside-none' as a fall-back session combination is
supported by this patch.

Fallback session feature is not available in the legacy mode.

can be configured to only affect the particular cores.

Because each FIFO is per core, the following fields have been removed

full barriers which will affect the performance, so add a per worker

Since the maximum core number can get to 256, so disable the per core

examples/ipsec-secgw: support fragmentation and reassembly

Add optional ability to fragment packet bigger then mtu,
and reassemble fragmented packet.
To minimize possible performance effect, reassembly is
implemented as RX callback.
To support these features ipsec-secgw relies on librte_ipsec ability
to handle multi-segment packets.
Also when reassemble/fragmentation support is enabled, attached
crypto devices have to support 'In Place SGL' offload capability.
To enable/disable this functionality, two new optional command-line
options are introduced:
--reassemble <val> - number of entries in reassemble table
--mtu <val> - MTU value for all attached ports
As separate '--mtu' option is introduced, '-j <val>' option is now used
to specify mbuf data buffer size only.
