2bf8fcd7c2 pbuf: Add pbuf_copy_partial_pbuf library function
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().

785b7aba3c Sockets: Unit tests and apps corrections
* 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()

f92d6702bc Sockets: declare msghdr->msg_iovlen as msg_iovlen_t
* 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.

3043d9d023 mDNS: move domain related functions and output related funtions
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.
