Added dummy backend which can be enabled with Kconfig. By default it is
disabled because it needs the same amount of memory as other phisical
backends. It shall be use only for commands testing purposes.
Improved shell_execute_cmd function, now it clears command context
before new command will be executed.

1. Changed return value of function: shell_cmd_precheck from bool to
int. Now it returns:
0 when argument count is correct and help print is not requested
1 when help was requested and printed
-EINVAL on wrong arguments count
This change simply shell_cmd_precheck usege in command handlers.
2. Unified all commands in shell_cmd.c file.
3. Fixed a bug where help was not printed on wrong argument count.

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.

The original code (introduced by commit d5db35204a) looked like this

However with the cleanup the logic seems to have gotten reversed.

Console subsystem is intended to be a layer between console drivers
and console clients, like e.g. shell. This change factors out code
from shell which dealed with individial console drivers and moves it
to console subsystem, under the name console_register_line_input().
To accommodate for this change, older console subsys Kconfig symbol
is changed from CONFIG_CONSOLE_PULL to CONFIG_CONSOLE_SUBSYS
(CONFIG_CONSOLE is already used by console drivers). This signifies
that console subsystem is intended to deal with all of console
aspects in Zephyr (existing and new), not just provide some "new"
functionality on top of raw console drivers, like it initially
started.

The code was completely broken wrt command lookups when the command is
given in the format "<module> <cmd> <args...>". It would only work if
the default module is not set, which is almost never the case (as most
apps set it explicitly).
Refactor the command handling by moving more logic up to shell_exec(),
so that get_cb() does a lookup for a single module

The way get_command_and_module() is used it's impossible for it to be

The way the command line parsing works, argv[0] is always guaranteed
to be non-NULL as well as a non-empty string, so doing checks for this

This adds shell_exec which can be used to execute commands directly
without the use of a console which is useful for both testing as well
as interfacing with applications/upper layer which would like to have

of using fifos like uart_register_input and telnet_register_input do.
