- 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.

If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.

net_nbuf_get_tx()
net_nbuf_get_data()
net_nbuf_get_reserve_rx()
net_nbuf_get_reserve_tx()

net_nbuf_copy()
net_nbuf_copy_all()
net_nbuf_push()
net_nbuf_append()
net_nbuf_write()
net_nbuf_insert()

net_nbuf_append_u8
net_nbuf_append_be16
net_nbuf_append_be32
net_nbuf_insert_u8
net_nbuf_insert_be16
net_nbuf_insert_be32
net_nbuf_write_u8
net_nbuf_write_be16
net_nbuf_write_be32
so they call the base function using K_FOREVER. Use the

is allocated.

The cause for this change is TCP. Until now, the radio strategy driver
(ALOHA or CSMA) was providing the actual nbuf, and not the buffer
fragment, counting on the fact that the loop was using
net_buf_frag_del() which made so, iteration after iteration, buffer
framgent to be always buf->frags. The problem with this logic is loosing
the fragments that might be still referenced by TCP, in case the whole
buffer did not make it so TCP can retry later and so on.
Instead, TX now takes the nbuf and the actual frag to send. It could
have been working with just a pointer on the data, and the whole length
of the frame. But it has been avoided due to possible future devices,
that will be smarter and run CSMA directly in the hw, thus it will
require to access the whole buffer list through the nbuf.

The 802.15.4 frame has a header and in the end after the payload a CRC.
Overall MTU is 127 bytes, but CRC is most likely going to be generated
by the device itself (offloading). Because the limitation of current
nbuf, it's not possible to keep this CRC in the buffer because it
require a user data size of 127 bytes but if we do so, IP stack will
fill in as much as it can as packet data, thus occupying the 2 last
bytes. This generates bugs. A perfect solution would be to generalize a
better handling of MTU and head or tail reserve data into nbuf, but
this will probably be solved in the future.
