94b5368388 Avoid malloc() in getsockaddr() 
The getsockaddr() function is used to allocate a struct sockaddr of the
right length and initialize it with userspace provided data.  It is used
for the connect(), bind() and sendit() family functions.  In particular,
the sendit() function is used by the UDP send functions.  This means
each UDP send needs a malloc() and free() invocation.  This is a
performance problem in RTEMS (first-fit heap) and may lead to heap
fragmentation.  Replace the malloc() allocation with a stack allocation.
This requires SOCK_MAXADDRLEN (= 255) of additional stack space for
libbsd.

A further optimization would be to get rid of the stack copy of the
socket address.  However, this would require to check each consumer of
the address to ensure that it is not modified.

02373194fe Update due to Newlib 2017-06-07 changes 
The following files are now provided by Newlib:

  * arpa/inet.h
  * net/if.h
  * netinet/in.h
  * netinet/tcp.h
  * sys/socket.h
  * sys/uio.h
  * sys/un.h

The <sys/param.h> and <sys/cpuset.h> are now compatible enough to be
used directly.

Update #2833.
