It's possible to get number of free pkts/buffers with just
CONFIG_NET_BUF_POOL_USAGE, whereas CONFIG_NET_DEBUG_NET_PKT
depends on CONFIG_NET_LOG and adds quite a bunch of other
overhead. Also, give a hint that this option should be enabled
to get free buffer numbers.
Additionally, use unambiguous "Total" wording to represend the
maximum capacity of data structures, instead of previous "Count".
"Count" (or at least counter) is intuitively something which can
change, so not seeing any other numbers, it's very easy to assume
that it's actually number of free buffers (because that's the
information a user may be interested in in many cases).

For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

Add support to print connection handler information in net-shell.
There exists one connection handler for each UDP/TCP port that we
are listening. These prints are only available if CONFIG_NET_DEBUG_CONN
is enabled because the net_context has the same information. Thus the
connection handler info is only printed if debugging is active in order
to verify that handler information is proper.

- 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.
