  5. packetblaster: Use default number of Intel rx/tx descriptors 

    This depends on the default number of descriptors being sane.
See merge 192f00c to ensure this.

This seems to work fine - tested line rate with minimum packet size on
10x10G per packetblaster process:

  6. core/packet.lua: Enable overflow check when allocating packets 

    Enable a really important assertion that the packet freelist does not
overflow when we allocate a new batch of packets.

This should not be a performance issue: the check is on a slow-path
where we are allocating a thousand new packets.

This is actually very important. I found a bug that packetblaster
would crash with heap corruption / segfault when you run it with more
than 3 network interfaces at the same time. This is because it
allocated too many packets for transmit/receive buffers and that error
was not caught unless "developer debug" mode was enabled.

(That problem is separately alleviated by #883 that reduces the
descriptor queues from 32K packets to 2K packets each.)

  1. core.packet: Extend max packets from 100K to 1M 

    Packets are allocated dynamically on demand and this is only an
artifical limit of "more than anybody should ever need" for catching
unbounded allocations (leaks). (The limit also serves to make the
freelist simple i.e. a fixed-size array.)

The previous value of 100,000 is too low to serve its purpose: it is
reasonable to allocate more than 100,000 packet buffers when managing
many network receive queues and wanting to avoid packet drops.
