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.

If TCP is activated, then the echo-server application starts
to listen TCP socket and reply data to caller. For TCP
connections, the application data is not reversed because
it would make it difficult to verify the data in the sender
side. The TCP packets might be split into smaller chunks by
echo-client so client would have some unnecessary difficult
to verify the data it sent if we reverse it.
