* Extend the memory available for the heap from 256k to 512k.

* Embed the stack into the bss section for loader and netboot.  This
  is required for netboot since otherwise the stack would be inside our
  heap.
* Install loader and netboot in /boot by default.
* Fix getbootfile so that it searches for a ',' instead of a ';'
  when terminating the filename.
