Make pppoe_create() actually store the passed service name and
concentrator name, so that they are passed in the PADI/PADR/PADS
packets.
Assume that the user application won't be freeing the strings and just
copy the string pointers, therefore remove the mem_free() in
pppoe_destroy().
Since only the pointers are copied now, make them 'const' in
pppoe_softc.

sc->sc_service_name and sc->sc_concentrator_name are best defined as
char* because there are passed to libc strings functions which expect
a char*.

Rename PPPOE_TODO to PPPOE_SCNAME_SUPPORT because this is the only
feature enclosed by them. Prepare for proper service name and
concentrator name support by moving PPPOE_SCNAME_SUPPORT define to
ppp_opts.h.

Reduce subdir string length by 3 bytes to make the warning go away. The whole file path including directory AND filename is limited to MAX_PATH_LEN - so it is reasonable to reserve 3 bytes less for directory - the filename won't fit anyway in the remaining 3 bytes.
If the host observes a response (after probing) containing RR's
that he thought were unique to him, there is a conflict. If a host
observes such conflict, it resets back to probing and the probing
procedures will resolve the conflict. (RFC6762 section 9)
Update mdns.txt for below API changes:
* mdns_resp_add_netif() no longer has dns_ttl argument
* mdns_resp_add_service() no longer has dns_ttl arguemnt
* mdns_resp_add_service() uses enum mdns_sd_proto for proto argument
* Add missing const qualifier at appropriate places

by replacing strnlen with strlen. It's a user-supplied string, so we can assume it is correctly \0 terminated (as done several times elsewhere in the code)
According to RFC6762 section 8.1:
If fifteen conflicts occur within any ten-second period, then the
host MUST wait at least five seconds before each successive
additional probe attempt.
If the host restarts mDNS, instead of a probe wait timeout randomly
chosen between 0 and 250ms, we wait 5s if more then 15 conflicts
occured in 10seconds. This flag is reset from the moment probing
succeeded.
mDNS: first version probe tiebreaking added
This first version works for our MCU boards but does only compare
the first question and answer. It does not sort the list of answers
and it does not search for answers or questions.
mDNS: improved probe question handling
For every probe question in our packet, we check the presence
in the incomming packet until we find a match. then we perform
the tiebreaking. At the moment we still only look at the first
answer.
mDNS: evaluate all answers in the authoritative section
The authoritative sections of both messages are evaluated.
The records that answer the probe question are sorted in to lists.
Then the lists are compared pairwise. A winner and a loser are
chosen and the host reacts on the outcome (ignore or stop probing).
mDNS: add support for name decompression in rdata when comparing.
For probe tiebreaking we need to compare RR's. It is possible that
the rdata of an RR contains compessed names (SRV record). We need
to decompress it first before we do the comparison.
Probe packet creation -> by splitting the definition and the sending
we can use the definition function for probe tiebreaking.
outpkt creation -> by splitting the creation and sending we can use
the creation function for probe tiebreaking.
The host only responded to a probe query via unicast because
according to the RFC, a probe should have the QU bit on.
This is a should and not a must so we need to be careful.
We added multicast probe answering support with the needed timouts.
Avahi for example probes with the QM queries. With this commit the
conflict is resolved.
It should be SYS_MBOX_EMPTY, not SYS_ARCH_TIMEOUT.
SYS_MBOX_EMPTY is defined to SYS_ARCH_TIMEOUT, so there is no bug.
But for good readability of the code, SYS_MBOX_EMPTY should be used.
