Avoid "LWIP_RFC7668_LINUX_WORKAROUND_PUBLIC_ADDRESS" redefined build
warning if it's set to 0 by lwipopts.h.

Works as expected, but some features are not implemented yet.

In contrast to netif_get_client_data, netif_alloc_client_data_id() is only
available if LWIP_NUM_NETIF_CLIENT_DATA > 0, not for DHCP etc.
This is correct in netif.c but wrong in netif.h
This reverts commit 6934bb442832406b5c41fc86bd934091b021f7ad.
Need to revert commit d6e58d02a619813a4187ab53ab0ffc2f0b864ad7 first, and that one produced merge conflicts.
enum tcpip_msg_type and struct tcpip_msg have members which are only
used when core locking and/or core locking input are disabled. Remove
these from the union to reduce the size. Remove from enum to prevent
usage when these are options are disabled
A quick sizeof test with MSVC 2013 showed a 4 byte size reduction for
struct tcpip_msg (16 bytes -> 12bytes) for the following configuration:
LWIP_TCPIP_CORE_LOCKING 1
LWIP_TCPIP_CORE_LOCKING_INPUT 1
LWIP_TCPIP_TIMEOUT 0
FIN should only be reported once (as '0' for sockets, as 'ERR_CLSD' for
netconns). Before this change, ERR_CLSD was returned forever...
This is the 2nd try. First try (commit ebcae98ae65c26a0c210c802540bf027d07fe2f1)
was buggy in that it could drop the FIN if it was read together with data
(reverted in commit ebcae98ae65c26a0c210c802540bf027d07fe2f1).
This version fixes this by adding an apiflag and a netconn flag to keep
track of this.

This hook is called from tcp_input() for all kinds of input pcbs when
selected to receive a pbuf (LISTEN, TIME_WAIT, rest). I can parse or
drop an rx pbuf.

This introduces the concept of ext (external/extended) arguments per
tcp_pcb (also for listening pcbs) to store more data than just one
"void *arg" per pcb. The "arg" is for use to applications, whereas
the ext_args may be used by frameworks and leave "arg" untouched.
In addition to a void pointer, callbacks are added to help frameworks
migrate arguments from listen pcb to connection pcb and to free args
when the pcb is freed.

This should make it easier to add debugging messages or other hooks
to the point where tcp pcbs are deallocated.

LWIP_HOOK_SOCKETS_SETSOCKOPT() and LWIP_HOOK_SOCKETS_GETSOCKOPT()
are introduced to implement additional socket options. The hooks
are always called first and report back if they handled the option
or not.

The LWIP_PBUF_MEMPOOL define used MEMP_ALIGN_SIZE instead of
LWIP_MEM_ALIGN_SIZE to calculate the element size of PBUF_POOL pbufs.
This is wrong for MEMP_OVERFLOW_CHECK, since MEMP_ALIGN_SIZE adds
MEMP_SANITY_REGION_AFTER_ALIGNED. This should be only added during
pool_base buffer allocation but for PBUF_POOL, it changed the size
of the pool elements.
