Message:

merge various cosmetic run-time support improvements

• coding style cleanups, comments cleanups, unsigned types for bit flags, indentation, etc.
• SYS_TASK_EXIT for proper termination of a task (optionally with udebug notification)
  • get rid of exit(), _exit(), core()
  • reimplement robust main(), exit() and abort()
  • call abort() if some part of libc initialization fails
• add more private libc headers to reduce the namespace pollution
