d569a22c73 tcpip: ensure core is locked for init done function 
This ensures the core is locked when executing the init done function
passed to tcpip_init

The could manifest as a synchronization issue during early init if
another thread was in the LwIP context at the same time

6af3b4accc netconn: Add LWIP_HOOK_NETCONN_EXTERNAL_RESOLVE (patch #9427) 
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

f5c37c8cbb Fix broken MSG_PEEK on TCP sockets (post-2.0.3 bug) 
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

b18e6a8734 sockets: fix missing break regression in event_callback 
During the refactoring in c5db278746, the
previous gotos were removed, but the lack of break statements in
NETCONN_EVNT_RCVMINUS and NETCONN_EVT_SENDMINUS was overlooked, leading
to incorrect fall through behavior

0882e0ba89 sockets: poll clean ups 
This makes the following poll cleanups:

 1) Add LWIP_ERROR in lwip_poll to check for invalid fds/nfds combinations.
    This fixes a possible a NULL fds dereference in lwip_poll_scan()
 2) Use has_ copies of the socket events in lwip_poll_should_wake() rather
    passing the sock pointer and accessing socket after leaving the critical
    section
