... and add a unit test for it.
Moved resetting netif->rs_count from all reports to link-up and netif-up only.
While at it, clean up the interface a bit so that netif->rs_count is touched
from nd6.c only.

This writes out the results of the unit tests in an XML file called
lwip_unittests.xml in the same directory as the unittests executable.
See https://libcheck.github.io/check/doc/check_html/check_4.html#XML-Logging
for an example of the ouput. Of particular use is the duration field, for
each test and for the entire test run.
Speed up test_pbuf_queueing_bigger_than_64k by using memcmp rather than
a byte by byte comparision. This allows using word aligned compares
within the memcmp implementation
This fixes a unit test timeout on my Windows 10 box with WSL which was
taking longer than 4 seconds for the unix port unit test to complete

This triggers bug #50914 (TCP_CHECKSUM_ON_COPY when adding data to
retransmission) when data is added to an already transmitted segment
with an uneven length of tcp data.
FIN should only be reported once (as '0' for sockets, as 'ERR_CLSD' for
netconns). Before this change, ERR_CLSD was returned forever...
This is the 2nd try. First try (commit ebcae98ae6)
was buggy in that it could drop the FIN if it was read together with data
(reverted in commit ebcae98ae6).
This version fixes this by adding an apiflag and a netconn flag to keep
track of this.
This fixes a bug in tcp_split_unsent_seg where oversized segments were not
handled during the split, leading to pcb->unsent_oversized and
useg->oversize_left getting out of sync with the split segment
This would result in over-writing the pbuf if another call to tcp_write()
happened after the split, but before the remainder of the split was sent in
tcp_output
Now pcb->unsent_oversized is explicitly cleared (because the remainder at
the tail is never oversized) and useg->oversized_left is cleared after it is
trimmed
This also updates the test_tcp_persist_split unit test to explicitly check for
this case
MSG_PEEK on TCP sockets was broken since commit b71d4477ea
from 06.03.2017: recv hung in an endless loop and tcp_recved() was called for peeked data
(which would result in a too large window advertised).
Aded TCP MSG_PEEK to socket unit tests
DHCP test code didn't set link up on net_test netif (exposed by changes
in 637bce91b4)
Then during the test_dhcp function, a Gratuitous ARP was not sent during
the call to dhcp_bind() because the link was still down
The sets the link state for all DHCP test functions
