Rename IP_HDRINCL to LWIP_IP_HDRINCL

Browse Source 
In the BSD socket API world, IP_HDRINCL is a socket option for "raw"
sockets that indicates whether sent packets already include an IP
header.  Within lwIP, "IP_HDRINCL" is redefined as a special value
that indicates to lwIP-internal functions that an IP header is already
included.  While somewhat related, the two meanings are different and,
on platforms that define the IP_HDRINCL socket option, this results in
a conflict.  This patch renames the lwIP one to "LWIP_IP_HDRINCL",
thus resolving the conflict.
