sys_arch_mbox_tryfetch() shall return SYS_MBOX_EMPTY or 0 according
to the documentation. Wherever the function is used the return
value is incorrectly compared to SYS_ARCH_TIMEOUT. For now
SYS_MBOX_EMPTY is defined to SYS_ARCH_TIMEOUT so this is not an
issue as long as SYS_MBOX_EMPTY isn't re-defined.

As written in RFC5227 in 2.1.1 Probe Details:
A host implementing this specification MUST take precautions to limit
the rate at which it probes for new candidate addresses: if the host
experiences MAX_CONFLICTS or more address conflicts on a given
interface, then the host MUST limit the rate at which it probes for
new addresses on this interface to no more than one attempted new
address per RATE_LIMIT_INTERVAL.
But `acd_restart` restart function check for `acd->num_conflicts > MAX_CONFLICTS`
which allow one more probe than expected.
So this commit change the test to `acd->num_conflicts >= MAX_CONFLICTS`.

* Socket functions definitions moved out of the
#define LWIP_SOCKET_EXTERNAL_HEADERS as all users who
set LWIP_SOCKETS to 1 will need them regardless they use
lwip's or external socket headers.
* Include lwip/inet.h in some unit tests and apps
* Since they use htons() and pals.
* test/unit/api/test_sockets.c:
* write() could be declared by external socket headers
* Call lwip_write() instead.
* Code expects fcntl() to return 6
* But O_RDWR could have another value if external
socket headers are present
* Replace 6 by O_RDWR.
* apps/tftp/tftp.c:
* recv() could be declared by external socket headers
* Rename it to tftp_recv()
* Lwip declares msghdr->msg_iovlen as int, but when
using external socket headers, some systems declare
msg_iovlen as size_t or others.
* This patch creates a new type msg_iovlen_t and
expects users to typedef it to the type they need
for their system.
Lwip's struct sockaddr includes sa_len, but some systems
like Linux doesn't have this filed, which produces many
compilation problems when using external headers.
A set of macros has benn added to detect the absence of
sa_len and adapt sockets.c
* LWIP_MARK_TCPIP_THREAD moved to include/lwip/sys.h
* Unix port macro definitions moved to sys_arch.h
* LWIP_MARK_TCPIP_THREAD
* LOCK_TCPIP_CORE
* UNLOCK_TCPIP_CORE
(goldsimon@gmx.de: fixed unix Makefile build and win32 build)

In timeouts.c commit 7d1c26cc0c replaced
timeout for AUTOIP with a timeout for ACD, however the value of
LWIP_NUM_SYS_TIMEOUT_INTERNAL was not updated and still counts
LWIP_AUTOIP instead of LWIP_ACD. If user has AUTOIP disabled (or not
explicitly enabled) and DHCP enabled, then ACD gets automatically
enabled too. In this case there will be one timeout too little for lwIP
and first TCP packet received causes an assertion.
Also add LWIP_IPV6_DHCP6 to the value of LWIP_NUM_SYS_TIMEOUT_INTERNAL,
as it was also not accounted for.
This reuses the member 'int socket' by making it a union containing
both int and void pointer.

The err field is removed from struct lwip_sock since commit e0a2472706
("netconn/sockets: remove fatal error handling, fix asynchronous error handling, ensure data before RST can be received")
sock_set_errno() simply calls set_errno() now, so use set_errno() instead.

If client reception buffer is bigger than the first frame we receive, the first packet test
will always fail for the second one if it is shorter the the diffence between reception
buffer size and first frame length.
For example, if we receive a PUBLISH message with length = 1517 (payload len = 1514 +
header len = 3), this result in total message length of 1517.
altcp_tls will send MQTT client frame up to 1516 bytes max. This result to PUBLISH
message splitted in two frame: first is 1516 bytes, the second of 1 bytes.
If MQTT_VAR_HEADER_BUFFER_LEN is 1520 (1516 + 4 bytes for stored fixed header), the
second frame of 1 bytes is considered as first publish frame because
client->msg_idx (1517) < MQTT_VAR_HEADER_BUFFER_LEN (1520).
This result in disconnection AND application callback never called for the end of the
payload.
The fix will check `(client->msg_idx - (fixed_hdr_len + length)) == 0` which can be
only true for the first frame of a message.
Below logs showing the bug:

When using the MEMP_MEM_MALLOC option, memp_malloc() can not be relied on to
limit the number of allocations allowed for each MEMP queue, as the ND6 code
had been. This caused the ND6 queue to keep growing until the heap allocation
failed when using the MEMP_MEM_MALLOC option. So add an explicit queue size
check in ND6.
Replace '\n' with '<br>', as this allows doxygen to understand reference
names followed by newline. For some cases just drop the newline if it's
not required.
Doxygen 1.8.15 doesn't like if the name of reference is followed by
anything else than (selected?) punctuation or whitespace.
