58ba1d834e net: nbuf: Fix net_nbuf_compact() API
Current API description of net_nbuf_compact() is not very clear.
The first parameter needs to be the first net_buf in the chain.

The changes to this API are needed in order to clarify following
use cases:
1) User provides fragment that is not first of the chain and compact is
successfully done. In this case there is no free space in fragment list
after the input fragment. But there might be empty space in previous
fragments. So fragment chain is not completely compacted.

2) What if input fragment has been deleted and api returns the same
buf?

So this commit simplifies the API behavior. Now net_nbuf_compact()
expects the first parameter to be either TX or RX net_buf and then it
compacts it. It fails only if the input fragment is a data fragment.

999338ea94 net: nbuf: Remove unused net_nbuf_push() API
The net_nbuf_push() API is not used by anyone. Semantics are not
clear and following patch requires changes to push api, so removing
this API for now. If needed this can be re-introduced later.

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.

6b069f1589 net: tests: Add unit tests for net_nbuf_compact()
The compact function was never really properly tested
but it is used by other routines that have unit tests.
This commit makes sure there is a special testing for
the buffer compact function.

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.

Jira: ZEP-1457

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.

- unified is the only kernel to be used now, removing unecessary kernel
type make option.
- removing all NANOKERNEL/MICROKERNEL related #ifdefs and so on.

c689fd6f1a net: Rename net_nbuf_write to net_nbuf_append
Current net_nbuf_write() api just appends data to last fragment. And
doesn't write data based on offset. That's why renaming this api.

New net_nbuf_write() apis based on offset will be coming soon.

ead511ddae net: Fix net_nbuf_read corner cases
Valid case:
 1) If the offset is more than current fragment length, adjusts offset
    from next relevant fragment and starts reading or skipping.
 2) If the read or skip length is more than available data length,
    then throw an error.

In case of an error, frag is 'NULL' pos is '0xffff'. Rest of the cases
are successful read and skip.
