0882e0ba89 sockets: poll clean ups 
This makes the following poll cleanups:

 1) Add LWIP_ERROR in lwip_poll to check for invalid fds/nfds combinations.
    This fixes a possible a NULL fds dereference in lwip_poll_scan()
 2) Use has_ copies of the socket events in lwip_poll_should_wake() rather
    passing the sock pointer and accessing socket after leaving the critical
    section

b9d3812ee8 Add assertion that netif index is within sane range in sockets.h. 
We can assert here since lwIP only supports <= 255 netifs due to netif index being an u8_t.

c5db278746 sockets: Refactor event_callback() 
This refactors event_callback() to separate updating socket event
state from processing the select list (to apply socket event change)

Refactoring changes:

1) select_list_cb processing has been moved to a new local function called
select_check_waiters()
2) goto no_select_wakeup has been removed and now we use a flag
to track whether to call select_check_waiters()
3) There is a small functional change for !LWIP_TCPIP_CORE_LOCKING.
We call SYS_ARCH_UNPROTECT after saving events but before calling
select_check_waiters() (which now calls PROTECT before starting the loop).
Before the code held the PROTECT across saving the events and the first
loop iteration, but this didn't protect against anything because each loop
iteration we do an UNPROTECT/PROTECT
4) Better documentation for both LWIP_TCPIP_CORE_LOCKING and
!LWIP_TCPIP_CORE_LOCKING

99e1f37b82 IP_PKTINFO: set msg_controllen upon output 
This fixes a bug where when writing IP_PKTINFO to msg_control, the
msg_controllen field was not updated with the length written

This bug is exposed by applications that provide a msg_control buffer large
enough for multiple control messages.  Then when calling CMSG_NXTHDR, it
returned a next cmsg pointer even though was no additional message

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
