The IP header was stripped by _net_app_ssl_mux() when it received
IP packet. This is fine but if the application expects the get
the IP header, then there is a problem. Fix this by saving IP
header to ssl_context and then putting it back in front of the
packet when the data is passed to application.
Note that this IP header is not used by net_app when the packet
is sent because TLS/DTLS creates a tunnel for transferring packets
and user can only sent packets via this tunnel.

The documentation says that the API will automatically append the
net_buf fragment to the end of network packet fragment chain.
This was not the case and current only user for this API in
echo-server sample appended the fragment itself. The fix is to
automatically append the fragment to the end of fragment chain.

- net_pkt becomes a stand-alone structure with network packet meta
information.
- network packet data is still managed through net_buf, mostly named
'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
memory when TCP is enabled.

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

Currently, the function accepts a struct sockaddr * but the code
immediately type casts this to either in_addr or in6_addr. This is
incorrect behavior as the first field in a sockaddr is sa_family_t
and not address data.
So without special knowledge, a developer will use a sockaddr structure
as the parameter and then wonder why the address information isn't being
set correctly.
Let's change this parameter to void * which makes this function similar
to inet_pton().

Let's make net stack having its own level of debugging through sys_log.
It replaces NET_DEBUG by NET_LOG_ENABLED, which is then semantically
better: someone wanting to log the errors might want that not only for
debugging.
Along with it, CONFIG_NET_LOG_GLOBAL option is added, in order to enable
all available logging in network stack. It is disabled by default but
might be found useful when warning/errors need to be logged, so it is
then unnecessary to selectively enable by hand all CONFIG_NET_DEBUG_*
options.
It is possible, locally, to override CONFIG_SYS_LOG_NET_LEVEL by setting
the level one want to NET_SYS_LOG_LEVEL. This can be useful on samples
or tests.
