3605e48c44 shell: Modify subcommands to use SHELL_STATIC_SUBCMD_SET_CREATE
It is planned to deprecate SHELL_CREATE_STATIC_SUBCMD_SET macro
which is replaced by SHELL_STATIC_SUBCMD_SET_CREATE.

Additionally, removed irrelevant comments about alphabetical
ordering which is no longer needed.

5451ff2848 shell: remove "options" concept
Removing help "options" from shell API.

Currently SHELL_OPT macro is not used by users. What is more
commit: a89690d10f ignores possible options created in
command handler by the user. As a result they are not printed
in help message.

Second, currntly implemented "options" in command handlers options are
implemented without SHELL_OPT macro.

And last but not least this change will allow to implement
help handler in a way that user will not need to think about calling
functions printing help in a command handler.

b0571746e2 shell: parsing output LF character
Some terminals literally interprets shell output data. Hence to print
a message in new line shell needs to send `\r\n` each time. To minimize
flash usage user can now send `\n` as a line delimiter and shell will
automatically add missing CR character.

2975ca0754 Bluetooth: Kconfig: Rename CONFIG_BLUETOOTH_* to CONFIG_BT_*
The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.

Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

3d498dd10c build: workaround build bug in tests
When an app uses a construct such as:

obj-y = main.o ../../../../samples/bluetooth/gatt/hrs.o

in its makefile, it causes said object module to be built in the
source tree, not in the object tree.

When building massively parallel, this usually resuls on the files
getting corrupted, leading to bugs such as:

https://jira.zephyrproject.org/browse/ZEP-2316
https://jira.zephyrproject.org/browse/ZEP-2317

src/../../../../samples/bluetooth/gatt/.gap.o.cmd:3: warning: NUL character seen; rest of line ignored
src/../../../../samples/bluetooth/gatt/.gap.o.cmd:4: warning: NUL character seen; rest of line ignored
src/../../../../samples/bluetooth/gatt/.gap.o.cmd:5: *** missing separator.  Stop.

as multiple build are trying to touch the same file in the source tree
and of course, race and causes a build bug.

We have known about this issue for a long time, but it requires
modifications in the build system that there is no time to tackle.

A suggested workaround is to include the source files into a local .c
file, so this is what this patch does, to remove the random noise.

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.

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.

7297f5db88 shell: move shell to its own subsystem
This moves the shell component into its own subsys and groups all
related files and options into a single place.

Additionally, one Kconfig option will now be required to enable the
shell:

 CONFIG_CONSOLE_SHELL=y

The header files was also moved to include/shell/shell.h and can be now
referenced with

 #include <shell/shell.h>

instead of

 #include <misc/shell.h>

Updated documentation as well.

71c7c01819 net: buf: Remove the need for net_buf_pool_init()
In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.
