db11fcd174 net/net_pkt: Fully separate struct net_pkt from struct net_buf
- 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.

bf964cdd4c net: Renaming net nbuf API to net pkt API
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.

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

5197266768 net: nbuf: Use net_nbuf_get_frag() to allocate a fragment
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.

d32503f57e net: nbuf: Split one global DATA pool to RX and TX DATA pools
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.

bd3908b2a9 net: nbuf: Add timeout to net_buf getters
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.

ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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.

66cfcc26bc tests: introduce Makefile.test
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
***** BOOTING ZEPHYR OS v1.6.99 - BUILD: Dec 21 2016 19:57:13 *****
tc_start() - Test Nanokernel CPU and thread routines

a1aa08c288 net: ip: Improve logging by adding a dedicated sys_log level
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.

954baea90b random: Restructure RANDOM Kconfig
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.

f903cb3763 net: dhcpv4: Implement XID
RFC2131 requires that a client must choose XIDs in order to minimize
the chance of collision with another client.  Selection of a random
XID at boot is a valid approach. Adjust the XID representation from
array of bytes to the more convenient uint32_t representation,
initialize the XID to a random number and increment for each request.

Refactor the dhcp test case to generate response messages with the XID
from the received message.
