Non-blocking sockets are almost never in the connected state when app try to
get result of connect success through poll, to avoid confusion because of
this error print, so downgrade the print level to warning.

IP_MULTICAST_IF (since Linux 1.2)
Set the local device for a multicast socket. The argument
for setsockopt(2) is an ip_mreqn or (since Linux 3.5)
ip_mreq structure similar to IP_ADD_MEMBERSHIP, or an
in_addr structure. (The kernel determines which structure
is being passed based on the size passed in optlen.) For
getsockopt(2), the argument is an in_addr structure.
refer to https://man7.org/linux/man-pages/man7/ipv6.7.html
IPV6_MULTICAST_IF
Set the device for outgoing multicast packets on the
socket. This is allowed only for SOCK_DGRAM and SOCK_RAW
socket. The argument is a pointer to an interface index
(see netdevice(7)) in an integer.

Using the macro places the buffers into .data section which means they
will consume the full buffer size of flash / read only memory as well.
Place the buffers into .bss to avoid this case.
Use PRIx64 which defines the width correctly regardless or architecture.
Fixes build error:

- Fix `ip6_map_ipv4addr` and `ip6_get_ipv4addr` macro to work under
different endianness.
- Use `iob_reserve` instead of `iob_trimhead` in `udp_datahandler`.
- Because we may set `sockaddr_in6` into IPv4 header, which causes
`offset` become negative. `iob_reserve` can hold this case while
`iob_trimhead` cannot.
- Select IPv4 domain in send case.

When do poll operation and the tcp connection state is TCP_ALLOCATED, eventset(POLLERR|POLLHUP) is return, causing the libuv poll_multiple_handles to fail.

Some programs use EAGAIN to determine whether all data has been read,
so cancel the error print when the error code is EAGAIN.

Write a packet, the length is bigger than CONFIG_DEV_FIFO_SIZE.
The return value should be -1, and the errno is EMSGSIZE.

The netdev of link-local address cannot be auto decided, and the link-local address should always be reguarded as address on local network.
The problem we met:
When using `icmpv6_autoconfig` with multiple netdev, the `icmpv6_neighbor` may take out wrong netdev with ip address already set, then it may send solicitation with wrong address (`dev->d_ipv6draddr`) on wrong device, and regard the link-local address as conflict (because `dev->d_ipv6draddr` exists on this network).

The memory allocated with strdup and asprintf is done via lib_malloc
so we need to use lib_free to deallocate memory otherwise the assertion
"Free memory from the wrong heap" is hit with flat mode and user separated
heap enabled mode.
