b881408ed7 Clean up the Range class and associated usages. The code was
never clear about whether the end of the range was inclusive
or exclusive.  Make it inclusive, but also provide a RangeSize()
function that will generate a Range based on a start and a size.
This, in combination with using the comparison operators, makes
almost all usages of the range not care how it is stored.

base/range.cc:
    Make the end of the range inclusive.

    start/end -> first/last
    (end seems too much like end() in stl)
base/range.hh:
    Make the end of the range inclusive.

    Fix all comparison operators so that they work correctly with
    an inclusive range.  Also, when comparing one range to another
    with <, <=, >, >=, we only look at the beginning of the range
    beacuse x <= y should be the same as x < y || x == y.  (This wasn't
    the case before.)

    Add a few functions for making a range:
    RangeSize is start and size
    RangeEx is start and end where end is exclusive
    RangeIn is start and end where end is inclusive

    start/end -> first/last
    (end seems too much like end() in stl)

    I don't know why we were using the superpage as the PCI memory addr.
    Changed and works correctly with detailed boot.

    LinuxSkipIdeDelay50msEvent was simply the same as the SkipFunc event,
    so I removed it. Same with with LinuxSkipFuncEvent.

3bfb59f70d Changes to fix bad DMA handling by disk when using scatter gather page
mappings (writes still unverified, and read could probably be looked over
a bit more too)

dev/ide_disk.cc:
dev/ide_disk.hh:
    Major changes to fix bogus handling of dma transfers.  The read seems to
    work pretty well, but the write is unverfied until we can get a disk
    image that actually tries to write.
dev/tsunami_pchip.cc:
    Change mask to properly mask 13 bits not 12
