mem: improve segment list preallocation

Current code to preallocate segment lists is trying to do
everything in one go, and thus ends up being convoluted,
hard to understand, and, most importantly, does not scale beyond
initial assumptions about number of NUMA nodes and number of
page sizes, and therefore has issues on some configurations.

Instead of fixing these issues in the existing code, simply
rewrite it to be slightly less clever but much more logical, and
provide ample comments to explain exactly what is going on.

We cannot use the same approach for 32-bit code because the
limitations of the target dictate current socket-centric
approach rather than type-centric approach we use on 64-bit
target, so 32-bit code is left unmodified. FreeBSD doesn't
support NUMA so there's no complexity involved there, and thus

vhost: fix error handling when mem table gets updated

When the memory table gets updated, the rings addresses need
to be translated again. If it fails, we need to exit cleanly

net/mlx5: support multiple groups and jump action

rte_flow has 'group' attribute and 'jump' action in order to support
multiple groups. This feature is known as multi-table support ('chain' in
linux TC flower) in general because a group means a table of flows. Example
commands are:

flow create 0 transfer priority 1 ingress
     pattern eth / vlan vid is 100 / end
     actions jump group 1 / end

flow create 0 transfer priority 1 ingress
     pattern eth / vlan vid is 200 / end
     actions jump group 2 / end

flow create 0 transfer group 1 priority 2 ingress
     pattern eth / vlan vid is 100 /
           ipv4 dst spec 192.168.40.0 dst prefix 24 / end
     actions drop / end

flow create 0 transfer group 1 priority 2 ingress
     pattern end
     actions of_pop_vlan / port_id id 1 / end

flow create 0 transfer group 2 priority 2 ingress
     pattern eth / vlan vid is 200 /
           ipv4 dst spec 192.168.40.0 dst prefix 24 / end
     actions of_pop_vlan / port_id id 2 / end

flow create 0 transfer group 2 priority 2 ingress
     pattern end
     actions port_id id 2 / end

With theses flows, if a packet having vlan 200 and src_ip as 192.168.40.1,
this packet will firstly hit the 1st flow. Then it will hit the 5th flow
because of the 'jump' action. As a result, the packet will be forwarded to
port 2 (VF representor) with vlan tag being stripped off. If the packet had
vlan 100 instead, it would be dropped by the 3rd flow.
