kernel: declare main and idle stack as globals
Renamed main_stack and idle_stack, to _main_stack and
_idle_stack, respectively, and made them globals. This does
not affect performance. They are still kept kernel private
symbols and not part of kernel API.
This will allow these symbols to be referenced in calls to
stack_analyse misc functions to profile stack usage in
applications.
