to insert areas so we don't overflow.
* Consequently use the area end (base + size - 1) where appropriate which
prevents overflows in a few places.
* Properly check for reaching the address space end.
* If we've already found a spot we don't need to recheck if we've found one.
* Simplify the B_EXACT_ADDRESS checks down to a simpler single if statement
instead of the four seperate ones.
* Properly calculate the search end for B_EXACT_ADDRESS as well, it's also
base + size - 1.
* Block the full last page now that this actually works without overflowing.
* Some style changes and added spacing.
This should now really fix #2550. Previously the overflow protection didn't
actually work because on allocation we overflowed and completely missed the
protecting area.

and 0xcccccccc (and 64 pages thereafter) in any way will always lead to a crash.
Before it could happen that these ranges were allocated for an area and then
accessing these would not be as evident anymore. Only enabled when the
corresponding paranoid setting is enabled (which it currently is).

of the VM functions handling areas are overflow safe. If an area is created that
spans across the last page many places will run into an integer overflow. This
mostly concerns the area allocation path in find_and_insert_area_slot() and also
vm_create_anonymous_area() where the loop for mapping pages for B_FULL_LOCK
areas overflows and runs more times than it should leading to #2550.
This could be seen as a workaround. The real fix would be to make everything
overflow safe. The thing is that this does also concern the user of the area
which could easily have forgotten to check for overflows as well, so I am a bit
uneasy with handing out areas that could easily lead to such hard to debug
problems. Since this is really an edge case and this single step safes quite a
bit of extra checks I'd actually be OK with keeping it that way.

(when some of the reserved pages have been allocated already) in
vm_page_num_unused_pages(). Before it could return negative and therefore

resetting the bus. This allows to skip devices that are not present. Works for
most but not all devices. Sometimes device 0 pretends that a device 1 exists,
but it's usefull anyway.
Allow working device 1 only configurations by not selecting device 0 anymore
for identification. Moved indentification from Reset into BusScan to do everything
in a single step. A SATA emulation in combined mode might have a slave (device 1)
only configuration when only one device is connected, depending on the port.
Also tested with PATA.
Recovery for lost interrupts. Works but is dead slow because of the timeout.
Bus reset isn't possible anymore, this needs to be implemented in a save way.
