Follow-up Comment #14:

I have made some more changes to this file to add some more checks and to
move all the compile-time checks out of the LWIP_DEBUG ifdef block.

I realised some of the checks were to compare with the number of pbufs usable
for outgoing packets, but of course we don't know how many PBUF_RAMs will be
created. We could put a maxmimum on that value by dividing down MEM_SIZE, but
there doesn't seem much point. So I have removed some of the TODOs.
 
There's still a check for the number of pool pbufs and TCP_WND though as I
think that's still valid for incoming packets.
