This embeds the log message source IDs inside the origin unit
as module IDs in Sys-T messages. This allows Sys-T message
parsers to see where the log messages are coming from.
This is enabled by default if using Sys-T catalog messages as
the collateral XML file contains the information to interpret
the module ID.

Timestamps can be 32 or 64 bit long based on the platform and
build configurations. The proper way to handle these timestamps
is to use the ad-hoc log_timestamp_t variable.
This patch fixes some timestamp's reference which were still
using uint32_t changing them to log_timestamp_t.
Moreover also a new config is added in order to print the
timestamp as the Linux's kernel format. This might be useful
in AMP platforms in which Linux's and Zephyr's logs must be
interleaved in order to get a more comprehensive log solution.

Add support for new API's log_backend_format_set and

for one backend and for all the active backends respectively.
Using format_set function pointer in log_backend_api struct as a hook
to set the log format at runtime in the backends. Add function pointer
table with helper functions to be used as a way to select log format.
Add supported log format types as macros to use with the API.

Reduced logging mode selection to deferred, immediate, minimal and

which can be used to explicitly select deprecated version.
From now on, chosing CONFIG_LOG_MODE_{IMMEDIATE,DEFERRED} will result
in version2.
Deprecated CONFIG_LOG2_MODE_{IMMEDIATE,DEFERRED} with cmake warning.

In std_print(), the log arguments were casted to uint32_t before
being sent further to the output function.
For integer types which can not be represented by uint32_t, the
degraded user experience may be acceptable.
However, for string arguments, the output function will eventually
dereference the pointer, so if the "char *" can not be represented
by uint32_t, bad things are going to happen. In practice you will see
this on 64-bit systems where sizeof (char *) is 8 byte and addresses
higher than 0x80000000.

Uart device is unique and thus does not need to be passed through the

MISRA-C Rule 5.3 states that identifiers in inner scope should
not hide identifiers in outer scope.
The log output instances all named "log_output" in backends
collide with the "log_output" parameter of various functions.
This renames the variables in the backends to make them
more descriptive. Same goes for the buffers for some of
these instances as they are all named "buf", and "hostname"
being used in the network backend, so they are renamed.
There are a few places where variables are overriden within
an inner scope (e.g. inside loop and if block) so they are
also renamed.

The hexdump was earlier printed using 8 bytes in one line like this
[00:00:00.131,143] <wrn> sample_instance.inst2: Example of hexdump:
01 02 03 04 05 06 07 08 |........
09 0a 0b 0c 0d 0e 0f 10 |........
11 12 13 14 15 16 17 18 |........
19 1a 1b 1c 1d 1e 1f 20 |.......
21 22 |!"
This is not utilizing the width of the output best way possible.
Better utilization of the output is to print 16 bytes in one line
like this:
[00:00:00.131,136] <wrn> sample_instance.inst2: Example of hexdump:
01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 |........ ........

21 22 |!"
In order to make it easier to find / calculate the bytes in the
output, print the output bytes in 8 byte groups.
This has the benefit that it is easier to map the Zephyr hex output
to Wireshark output which prints the bytes like this.

Rename reserved function names in the subsys/ subdirectory except

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.
This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.
All files that use these macros have been updated.

The new Logger subsys uses a very robust formatter function in minimal
libc: _prf(). This adds up to ~3K flash. For resource constrained
devices running samples that don't use the extra formatting options,
allow them to select LOG_DISABLE_FANCY_OUTPUT_FORMATTING to revert
back to vprintk.
MCUBOOT is one such sample that has a very limited amount of output
and benefits from the flash savings due to small bootloader partition
sizes.
