The code used net_nbuf_get_reserve_{rx|tx}_data() function to
allocate a fragment. Instead of that low level function, use
net_nbuf_get_frag() instead. There are few places this is not
possible or is too big change like in few test programs.

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.

Using net_buf_unref() technically works but debugging the network buffer

This commit changes the net_buf getter functions in nbuf.h
by adding a timeout parameter. These function prototypes
are changed to accept a timeout parameter.
net_nbuf_get_rx()
net_nbuf_get_tx()
net_nbuf_get_data()
net_nbuf_get_reserve_rx()
net_nbuf_get_reserve_tx()
net_nbuf_get_reserve_data()
net_nbuf_copy()
net_nbuf_copy_all()
net_nbuf_push()
net_nbuf_append()
net_nbuf_write()
net_nbuf_insert()
Following convinience functions have not been changed
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
base function if you want to have a timeout when net_buf
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.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

To customise test builds and support test related features such as time
stamps and a boot banner, introduce a Makefile variant that is dedicated
to testing.
Initially we introduce a new config overlay that is used for all tests, in
this case we enable BOOT_BANNER and BUILD_TIMESTAMP. This will print the
current version and the date, useful when reporting bugs and also an
indicator that the system has booted before the test has started.
For example:
[QEMU] CPU: qemu32

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.

Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu. Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom. Do not present pseudo generators if a true random generator
is presented.
This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.
In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.
Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

Reassembly IEEE 802.15.4 fragments as per it's datagram size
and datagram tag. Uncompress IP header fragment as soon as it
arrives. Size matches only after uncompression of IP header with
total length.
Support added for multiple IP packet reception. Default is one full
IP packet at a time. Cache size can be modified via Kconfig option
(NET_L2_IEEE802154_FRAGMENT_REASS_CACHE_SIZE).
Note: If you increase the size by 1 means, you should have N number
of data buffers available at max.
e.g. One full IP packet (1280 MTU) needs 15~16 data fragments means,
multiply size by same number of fragments. It requires more memory.
Offset based reassembly yet to be done (fragments can come in any order
[e.g. mesh]). Now assuming that fragments are in right order.
