[lwip-devel] [task #7017] Implement DNS client

[Simon Goldschmidt]

Follow-up Comment #32, task #7017 (project lwip):

I've created a function netconn_gethostbyname (in api_lib.c),
do_gethostbyname(in api_msg.c) and gethostbyname (in sockets.c, using
netconn_gethostbyname).

Almost everything is pretty straightforward except for the method to block
the application thread: I've had to allocate a semaphore for every call to
netconn_gethostbyname, since there is no netconn available (or else
gethostbyname would need a socket parameter).

If this is OK, implementing the remaining functions (_r or whatever) isn't
that hard.

Pls see attached patch.
