Like pbuf_copy, but can copy part of a pbuf to an offset in another.
pbuf_copy now uses this function internally.
Replace pbuf_take_at loop in icmp6 with pbuf_copy_partial_pbuf().

cc1: all warnings being treated as errors
With the payload lengths not matching between source and destination.
Also remove redundant allocation check in other test, it is now done
in the test setup code.
When using LWIP_RAND_FOR_FUZZ_SIMULATE_GLIBC:
fuzz_common.c: In function ‘lwip_fuzz_rand’:
fuzz_common.c:683:11: error: comparison of integer expressions of different signedness: ‘int’ and ‘long unsigned int’ [-Werror=sign-compare]

Fuzz tests need reproducible code, so we need an "unsafe" version of
LWIP_RAND() in this case...
Also, to reproduce fuzz tests cases from Linux on Windows,
LWIP_RAND_FOR_FUZZ_SIMULATE_GLIBC provides the first 20 random numbers that
glibc would have...
* Include lwip/inet.h in some unit tests and apps
* Since they use htons() and pals.
* test/unit/api/test_sockets.c:
* write() could be declared by external socket headers
* Call lwip_write() instead.
* Code expects fcntl() to return 6
* But O_RDWR could have another value if external
socket headers are present
* Replace 6 by O_RDWR.
* apps/tftp/tftp.c:
* recv() could be declared by external socket headers
* Rename it to tftp_recv()
* Lwip declares msghdr->msg_iovlen as int, but when
using external socket headers, some systems declare
msg_iovlen as size_t or others.
* This patch creates a new type msg_iovlen_t and
expects users to typedef it to the type they need
for their system.
Fix building unit tests via contrib/ports/unix/check on Debian 9, gcc 6.3.0.

mDNS.c needed to become cleaner. Domain related functions are
moved to the mdns_domain.c util module. The output related
functions are split off (clear separation between defining the
packet and generating the packet). The output functions can
now be found in mdns_out.c.
mDNS move probe question packet generation to mdns_send_outpacket
The probe any questions were added to the pbuf in the send_probe
routine. It is better if we move all pbuf generation to the output
function so later on packets can be delayed etc. keep it all in
one place.
mDNS: move legacy question generation to mdns_send_outpacket
It's better to do the pbuf generation in one place.
Especially important for message delaying etc.
mDNS take out domain related functionality and put in other file.
The mDNS file is getting very big and a lot still needs to be added.
For clarity reasons it's better to split these domain functions
from the main mDNS file.
mDNS split off output related functionality and put in other file
A lot of functions are only needed for the generation of the pbuf,
by separating them into another file we clean up the mdns file.
We only need the mdns_send_outpacket function as interface.
Packet definition is now completely separated from packet
generation.
I disabled the yet unfixed tests to test if the new travis
integration works. Still working on them...
