* libmisc/shell/shell.c, libmisc/shell/shell.h: Changed type for

boolean values from 'int' to 'bool'.  Added option 'login' to enable or
	disable a login prompt.  Changed intialization of global shell
	environment to static initialization.  Changed stack size type to
	'size_t' conforming to classic API.

	* libmisc/shell/shellconfig.h: Fixed some typos.
