Adding mechanism to all the backends to switch the logging formats
at runtime while leveraging the function pointer table based upon
the Kconfigs which also cleans up the logging backend design.
Also demonstrate the working API with the changes
to syst sample. Clean up Kconfig for backends and add a standard
template to generate the Kconfigs for logging formats to be used
by all backends.

Reduced logging mode selection to deferred, immediate, minimal and
frontend. Decoupled logging version from mode and created CONFIG_LOG1
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.
Codebase adapted to those changes.

Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce
flash footprint.

Uart device is unique and thus does not need to be passed through the
logging context. Only the assert() requires a void * cast.
On log_output side, the device usage was removed. It is actually unclear
why it has been set like this since depending on the context, it can be
anything and not specifically a device.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

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.

move uart.h to drivers/uart.h and

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

It may happen that panic occured while logger backend
was formatting output data. In that case output buffer
could get corrupted as logger assumes that processing
happens in one context only (panic is the only exception).
Added log output buffer flushing on entering panic state.

Extended macro to accept flag indicating if given backend must be
initialized and enabled when log subsystem starts. Typically, simple
backends will have autostart flag set. More complex may require
explicit enabling (e.g. shell over BLE can only be enabled when
BLE connection is established).

Adding new implementation of logging subsystem. New features
includes: support for multiple backends, improving performance
by deferring log processing to the known context, adding
timestamps and logs filtering options (compile time, runtime,
module level, instance level). Console backend added as the
example backend.
