Fields sin6_len and sin_len are always used in the file but not all implementations of sockaddr_in or sockaddr_in6 have this fields (including Linux implementation).
Added #if-check to avoid compilation errors in such cases.
Defines EINVAL and ERANGE are used in the file but not included directly. When I try to use <sys/socket.h> and <arpa/inet.h> as LWIP_SOCKET_EXTERNAL_HEADERS it causes errors with this defines.
See bug #57445. Short version of the description there: lwip_select() failed
to decrement 'select_waiting' of a socket since that code part failed on
'free_pending' sockets. However, the code does not have to check that as it
has marked the socket to be in use itself earlier.

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.

* 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
This reuses the member 'int socket' by making it a union containing
both int and void pointer.
See bug #56593.

The err field is removed from struct lwip_sock since commit e0a2472706ee
("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.

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.
bug #56004
lwip_getsockopt_internal/lwip_setsockopt_internal were renamed to
lwip_getsockopt_impl/lwip_setsockopt_impl. Update the comment accordingly.

This reverts commit 8b4a8159a898795ef0fc9226dae1ce66531ad487.
We do not want to do this shortly before a release. Reformatting (buggy reformatting) may introduce new bugs.
Threads blocked on the rx mbox are counted and on close,
one "netconn closed" message per thread is posted to the mbox
to ensure all threads are woken.
The netconn can then be safely deleted. In socket API, "fd_used"
and "fd_free_pending" help with auto-deleting the netconn.

This is necessary to implement fullduplex sockets that are closed asynchronously:
the netconn in the socket must not be freed before all threads have given up
using it.
We now call the first part of 'netconn_delete()' (moved to 'netconn_prepare_delete()')
from lwip_close() and only actually end up calling 'netconn_free()' from
'free_socket()', which might be called later if LWIP_NETCONN_FULLDUPLEX is enabled.

Calling SYS_ARCH_PROTECT() could happen twice in 'free_socket()' if
that free was executed delayed (e.g. in 'done_socket_locked()').
