2f117add7a sockets: task #14247, add CMSG and IP_PKTINFO 
This commit adds CMSG infrastructure (currently used with recvmsg) and
the IP_PKTINFO socket option.

In order to use IP_PKTINFO, set LWIP_NETBUF_RECVINFO to 1

Unit test is added to verify this feature

8e83e206f4 sockets.c: Make sock_inc_used overflow check robust. 
Before this patch, it was possible that the overflow check might
miss an overflow event.

e.g. Consider 2 threads, both executing this method. u8_t fd_used is on 255...

Thread A -> atomically increment fd_used (which is now 0)
Thread B -> atomically increment fd_used (which is now 1)
Thread A -> check overflow... sees everything ok
Thread B -> check overflow... sees everything ok

And the overflow is missed :(

2980f7cc58 Vectorize netconn_write for TCP 
This commit adds support to the netconn write APIs to take an input of
vectors instead of a single data pointer

This allows vectors sent on a TCP connection via sendmsg to be treated
atomically.  The set of vectors is segmented into as much data as can
fit into the send buffer and then the TCP output function is called

Previously, each vector was passed to netconn_write_partly and tcp_write
segmented it into its own packet, which was then it was sent via
tcp_output (if not Nagleing)

This commit adds vector support to lwip_netconn_do_writemore() which
is the meat of the TCP write functionality from netconn/sockets layer.
A new netconn API netconn_write_vectors_partly() takes a set of vectors
as input and hooks up to do_writemore()

This commit also defines IOV_MAX because we are limited to only
supporting 65535 vectors due to choice of u16_t for the vector count
