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
Include lwip/sys.h to fix below build error:
../../../../lwip/src/apps/httpd/httpd.c:470:23: error: implicit declaration of function ‘sys_now’ [-Werror=implicit-function-declaration]
u32_t ms_needed = sys_now() - hs->time_started;

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
Use NETIF_FOREACH macro to get some optimizations for LWIP_SINGLE_NETIF case.

We preserved the TIME_WAIT handling before, but it seems this is not correct: we want to issue
a RST later again if someone wants to talk to this port. With TIME_WAIT, this might not always
the case.
Slightly better readability by calling dns_backupserver_available()
instead of open-coded. Also move dns_backupserver_available() function
up to avoid forward declaration.

- call conn->err() instead of conn->recv() if handshake fail and free conn
- close inner_conn and free current conn in altcp_mbedtls_close()

Partly revert commit 0486100a2b from 07.08.2017 as it breaks layering: every layer must free its own altcp_pcb. Freeing the inner_conn is not the right way.
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
This fixes a bug where some callers of netif_issue_reports were not
checking that both link and admin states were up, leading to extraneous
reports when calling one of the following
1) netif_set_ipaddr
2) netif_ip6_addr_set_parts
3) netif_ip6_addr_set_state
The bug has been fixed by placing link and admin state checks in
netif_issue_reports and not requiring the callers to perform this
checking

It does not make sense to return success in p == NULL or
invalid header_size_increment/header_size_decrement cases. Fix it.

The macros are functions from ctype.h, but ctype.h declares them as functions, not as #defines
It makes no sense to abstract them in lwIPs portability layer, the functions are of low complexity and they are only used in this file.
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
