shell: added SHELL_AUTOSTART configuration option

Browse source 
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.
