If bypass mode is left outside of the registered bypass handler, the
command buffer was not cleared, basically containig leftovers from the
processing of the previous command. This resulted in undefined behaviour
on consecutive shell operations.

In some applications, there is a need to don't start the shell by
default, but run it later on some special condition.
When SHELL_AUTOSTART is set to n, the shell is not started after
boot but can be enabled later from the application code.

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.

Getopt has been rework in this way that calling it does not require
extra state parameter and its execution is thread safe.
Global parameters describing the state of the getopt function have been
made available to ensure full API compatibility in using this library.
However, referencing these global variables directly is not thread
safe. In order to get the state of the getopt function for the thread
that is currently using it, call: getopt_state_get();
Extended the library with getopt_long and getopt_long_only functions.
Moved getopt libary from utils to posix.

Currently, in Zephyr the shell thread is the lowest priority i.e.
K_LOWEST_APPLICATION_THREAD_PRIO. Due to this all the other threads can
preempt the shell thread. Proposed solution is to add Kconfig which
gives the flexibility to change the priority of the shell thread.
This is now implemented using a new Kconfig variable
SHELL_THREAD_PRIORITY_OVERRIDE. By setting this option
SHELL_THREAD_PRIORITY can be set.

Shell uninitialization is not synchronous, it is deferred to shell
thread so resources used by the shell (e.g. transport resource like
uart) cannot be used until it is completed. Added callback which
notifies when all resources are released and shell is uninitialized.
Callback is called from shell thread just before it is aborted.

This functionality is is enabled by setting CONFIG_SHELL_GETOPT.
It is not active by default.
User can call following functions inside command handlers:
- shell_getopt - getopt function based on freebsd implementation
- shell_getopt_status_get - returns getopt status
Beware when getopt functionality is enabled shell will not parse
command handler to look for "-h" or "--help" options and print
help message automatically.

Commit 770f232a67 removes an array
termination from the shell_make_argv function. This function was
called from two functions: execute and tab_handle. In the mentioned
commit termination was added only in the execute function.
As a result calling tab_handle function was causing a segmentation
fault. This fix adds array termination to the tab_handle function.
