e9bd31b190 icmp6: Fix "LWIP_ICMP6_DATASIZE" redefined build warning if it was set to 0 
Need to undefine LWIP_ICMP6_DATASIZE before change the setting.
While at it, also remove the unneeded #ifndef LWIP_ICMP6_DATASIZE
checking because it is set in lwip/opt.h.

The experimental multi-packet mode splits input bytes depending on a length
decoded from the first 2 bytes and does that until the end of input.

This reverts commit 2390eb6826.
I've already marked other issues like this as 'invalid', so do this here, too.
Although I don't like the code, there's not much use in fixing this in one place only.

e926779510 netif_alloc_client_data_id: only present if LWIP_NUM_NETIF_CLIENT_DATA 
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

b5e67f142a tcp: LWIP_CHECKSUM_ON_COPY: fix adding data to retx segment 
See bug #50914( TCP_CHECKSUM_ON_COPY when adding data to
retransmission): when adding data to an already transmitted segment
that has an uneven length, the checksum was wrong.

To fix this, tcp_output_segment has to restore seg->chksum_swapped
before returning.
