We have projects that need to sense ip address changes in time,
and set ip address or clear ip address through netlink
so the relevant implementation is added.
The usage and command structure are consistent with linux

* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCGIFHWADDR provides the hardware
address (e.g., Ethernet MAC, etc.) of a network interface. It is
based on Linux. (BSD-based systems don't have this ioctl.) The Linux
implementation sets sa_family to ARPHRD_ETHER for Ethernet and IEEE
802.11 interfaces [1]. NuttX was setting it to NET_SOCK_FAMILY for
these interface types as well as 6LoWPAN and PKTRADIO; this was
incorrect and also the value of NET_SOCK_FAMILY varies based on
Kconfig settings. Correcting this to ARPHRD_ETHER for Ethernet and
IEEE 802.11 and ARPHRD_IEEE802154 for 6LoWPAN and PKTRADIO.

* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCSIFHWADDR sets the hardware address
(e.g., Ethernet MAC, etc.) of a network interface. Radio devices may
have different lengths of hardware addresses, such as
NET_6LOWPAN_EADDRSIZE (8), NET_6LOWPAN_SADDRSIZE (2), or
RADIO_MAX_ADDRLEN (8). Also, Kconfig CONFIG_PKTRADIO_ADDRLEN allows
the user to set any arbitrary size. Note that while the sister ioctl
SIOCGIFHWADDR "get hardware address" copies
`dev->d_mac.radio.nv_addrlen` bytes, SIOCSIFHWADDR was copying
NET_6LOWPAN_ADDRSIZE bytes unconditionally. Depending on which radio
is used, this could be incorrect. Fixing it to use
`dev->d_mac.radio.nv_addrlen` for SIOCSIFHWADDR as well. Also adding
DEBUGASSERT to ensure this is within bounds of source and
destination of the copy.
This fixes a regression caused by the following commit,
which prevents the file flag from being updated.

Note: some applications like mbedtls uses F_GETFL to confirm
the nonblock-ness of the socket. This is critical for such
applications.

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
