Subject: feat(kernel): see below for the commit's details.

what?
 - UserProcessScheduler and CoreProcessScheduler have been
extended for FILE_TREE and also HEAP_TREE structures.
 - DDK device's API will use dk_ calls instead of sk_ calls.
 - SIGTRAP and Interrupt handlers have been fixed to handle when no
   process is being run, and the kernel is instead raising the
interrupt.
 - Add file for HeFS formating in DiskImage.fwrk
 - Replace generic handler with breakpoint handler in int 3.

why?
 - These changes are bug fixes and improvements.
