base-hw: rename Core_thread Core_main_thread

Browse Source 
The class name Core_thread in Kernel for the object of the first thread of
core is too generic as there can be an arbitrary number of threads in core
besides this one. Furthermore, creating a core thread has its own syscall
'new_core_thread' that isn't related in any way to Core_thread. Therefore
this commit introduces the more specific name Core_main_thread as replacement
for Core_thread.
