On OpenFirmware, and possibly kboot, we use full path names for the
objects that are the 'device'. kboot uses a hack of knowing that all
disk device nodes start with '/dev', but this generalizes it for
OpenFirmware where both 'block' and 'network' devices live in the same
namespace and one must ask the OF node its type to know if this device
type matches.
For drivers that don't specify, the current convention of using
strncmp() is retained. This is done only in devparse(), but everything
uses it directly (or will soon).

devinit() marches through all the devices, calling the inint routines if
any exist. Replace all the identical copies of this code.

devparse is now the preferred interface to use to parse device
strings or device:/path strings. It parses the passed in string,
mallocs the device's particular devdesc string and returns the
'remainder' of the device:/path for further processing.

Allow device classes to define a parsing routine. Most device classes
already have these routines, but there's much duplication in their
use. Define an interface for a common routine to parse an individual
device. By convetion, files have the form "[device:]/path/to/file"
where device is optional (filled in to be the value of currdev)
and it starts with the dv_name field of the device, with the rest
of the name up to the device (typically a unit number, but disks
add partition inforation, and other devices may do artibtrary
otehr things).

- jhb implemented UFS write support a little over 16 years ago.
- Update the library name while we're here.
