Leandro Pereira 4e439653aa net: connection: Zero out connection struct when unregistering
Zeroing-out all bytes from a connection structure when it's
unregistered ensures all state from a previous connection is gone and
can't be mistakenly reused.

Leandro Pereira 86e0cce541 net: Fix out-of-bounds access when registering connections
If either a remote or a local address were supplied to the
net_conn_register() function, the IP stack would proceed to copy
sizeof(struct sockaddr) bytes from the respective remote_addr
or local_addr pointers, regardless of the actual size of the storage
these pointers point to.

Use the proper size depending on the socket address family.

Paul Sokolovsky dcb80f7ab8 net: struct sockaddr should have field "sa_family"
POSIX requires struct sockaddr's field to be named "sa_family"
(not just "family"):
http://pubs.opengroup.org/onlinepubs/009696699/basedefs/sys/socket.h.html

This change allows to port POSIX apps easier (including writing
portable apps using BSD Sockets compatible API).

Jukka Rissanen f673a701f9 net: pkt: Add CONFIG_NET_DEBUG_NET_PKT_ALL option
This option enables full debugging output for memory allocations.
As that can produce lot of output and slow down the device under test,
it is disabled by default.
The previous CONFIG_NET_DEBUG_NET_PKT will collect information about
memory allocations but will not print any output. Use "net mem" or
"net allocs" commands in net-shell to see the memory allocation status.

Jukka Rissanen 5325c4b594 net: tcp: Set the TCP sent flag after really sending pkt
Make sure that the sent flag is only set after we have really
sent the packet and the driver has verified that.
If the net_pkt_set_sent() is called while still in tcp.c, then
depending on how fast the device is, it might happen that the
retry timer expires before the packet is actually sent. This was
seen in frdm-k64f with ethernet and various debug prints activated.

The second 'const' is misguided, indicating that the returns pointer
value itself cannot be changed, but since pointers are passed by value
anyway this is not useful and was generating warnings with XCC.

The leading 'const' indicates that the memory pointed to is constant,
which is all we needed.
