Preliminary restructuring layout (was Re: sys/ tree re-structuring proposal)

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    I've been messing around with a copy of the cvs tree and this is what
    I have so far.

    I gave up trying to split things up by bus (isa, pci, etc..) because
    there are a lot more multi-bus drivers then I thought there were.  So
    instead I am splitting things up by function.  This seems to give us a
    nice layout.

    Most of the work is obvious but also note that I've moved all the 
    high level interfaces which 'attach' and 'detach' things into the bus/
    directory.  So, for example, cam, usb, and firewire are in bus/, but
    drivers that run under them or through them will be placed in dev/.
    Generic tie-ins, such as a firewire or usb storage device tying into CAM,
    is handled directly by the firewire bus code (just like now).

    Also note that architecture-specific drivers will be in subdirectories
    under dev/<function>, the idea being that there isn't a whole lot of it
    and it's better to keep things grouped by function so all of our ethernet
    drivers (for example) are in dev/netif.

    modules/ will be removed entirely and its Makefile's will be integrated
    into the appropriate drivers.  Having a separate modules/ directory
    hierarchy was a terrible idea and we are well rid of it.
