The comment in dhcp_handle_ack for 'offered_si_addr' states:
'boot file name copied in dhcp_parse_reply if not overloaded'
However this code was never reached if the packed was not 'overloaded'

The code to migrate flags from original segment updating wrong variable
so both remainder and remainder_flags may be incorrect. Fix it.

As the common code to call tcp/udp/raw_netif_ip_addr_changed is called
by multiple places, add netif_do_ip_addr_changed() to call them.

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.

struct netifapi_msg is defined in lwip/priv/api_msg.h rather than
lwip/netifapi.h. Thus remove include of lwip/netifapi.h from memp.c.

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.
This hook is called from tcp_input() for all kinds of input pcbs when
selected to receive a pbuf (LISTEN, TIME_WAIT, rest). I can parse or
drop an rx pbuf.

This introduces the concept of ext (external/extended) arguments per
tcp_pcb (also for listening pcbs) to store more data than just one
"void *arg" per pcb. The "arg" is for use to applications, whereas
the ext_args may be used by frameworks and leave "arg" untouched.
In addition to a void pointer, callbacks are added to help frameworks
migrate arguments from listen pcb to connection pcb and to free args
when the pcb is freed.

This should make it easier to add debugging messages or other hooks
to the point where tcp pcbs are deallocated.

tcp_rst, tcp_send_empty_ack, tcp_keepalive and tcp_zero_window_probe
all execute the same instructions to send a segment pbuf.
Combined into tcp_output_control_segment().
