This can be used to post preallocated messages from an ISR to the tcpip thread
when using FreeRTOS, where where calls differ between task level and ISR level.

This broke when IPv6 got scopes added. Scopes/zones are checked
even if none of the compared addresses are link local.
Result of the bug was that IPv6 replies were always sent unicast to
the source instead of to the multicast address.
Add ip-generic version that ignores IP zone info, since the v6 group
address is not tied to any netif.
Changes made by me:
- Move all error handling code into mdns_resp_announce() so it can be safely used by external code
- Remove mdns_resp_netif_settings_changed() because it is the same as mdns_resp_announce() after my changes
- Declare #define for a "thread-safe" version of mdns_resp_announce in mdns.h instead of netifapi.h - I don't want to intermix netif API with APPs
Current code only works if the argument happen to be named as fraghdr,
fix it.

This adds const to the sntp servername get/set API and internal storage
SNTP's usage of this name is read only and SNTP only passes it to dns_gethostbyname()
This was found by compiling with GCC -Wwrite-strings which makes the literal
SNTP_SERVER_ADDRESS a const string. This then produced warnings with sntp_init()'s
call to sntp_setservername()
lwip_isdigit/isxdigit/islower/isspace takes int as argument, so
explicitly cast to int to silence below build warnings.

This adds a new hook allowing an external DNS resolver to be hooked into
netconn_gethostbyname(). The hook can handle some or all of the queries
One use case for this hook is to run mDNSResponder in the same system as LwIP
(mDNSResponder also uses LwIP's socekt APIs) and have it handle .local queries
while LwIP stack handles unicast DNS queries
ARMCC when using __packed structures will not implicitly convert a
pointer to a member of a packed structure to something which does not
have __packed. This results in a compiler error and was found with calls
to icmp6_param_problem
While there is a #pragma pack mode in ARMCC that disables this error, it
does require existing ports to switch over their packing mode and
perform integration
Current newlib does not define O_NDELAY, but it needs to be the same
as O_NONBLOCK rather than using the lwip value of 1.

This makes two cleanups that follows the same organization as close/closesocket:
1) There is no lwip_ioctlsocket. Instead lwip_ioctl should redirect to ioctlsocket
2) With LWIP_POSIX_SOCKETS_IO_NAMES enabled, lwip_ioctl/ioctlsocket should redirect to ioctl
Some systems need to take into account an RX buffer pool size when
advising an appropriate number of RX pbufs to queue on the ooseq
list. For some systems there is a practical hard limit beyond which
the rx pool becomes exhausted blocking reception of further buffers
until some are freed.
It also helps to be able to consider the available dynamic memory when
advising an appropriate maximum number of bytes to buffer on the ooseq
list.
These decisions can also benefit from knowing the number already
allocated on a particular pcb, so the ooseq tcp segement is passed to
these functions. For example, if the system only wants to allow the
total number of rx pbufs queued on all the ooseq lists to grow by one
and a pcb already has two then it can return three for this call, but
might return one for another call - supporting a greedy allocation
strategy.

For this, convert 'u8_t nexth' to a pointer and change 'icmp6_param_problem()' to take a pointer, not an offset number
