"IP_HDRINCL" is a name of a socket option and the #undef of it is a
good sign that reusing this name was rather unfortuate. Other naming
conflicts are mostly restricted to "lwip/sockets.h" but this one is
pretty nasty since it affects all code that uses lwip. Rename it out
of the way in "lwip/ip.h" and do undef/redef dance in the few lwip
files that use this name to minimize diffs to upstream.
