sys: Split struct device into a private device_impl.h.

Include this only inside autoconf itself, and a few files that abuse
autoconf in ways I can't confidently make easy fixes for.

XXX kernel ABI change requires bump -- no more use of struct device
internals allowed, previously done by some drivers

driver(9): New device_set_private.

Used to initialize a device_t's private pointer at most once.  Only
for drivers with zero cfattach size so autoconf doesn't preallocate;
KASSERT checks for this mistake.

Introduce a generalized "device handle", designed to abstract the handles
used by platform description mechanisms like OpenFirmware, Device Tree,
and ACPI.  In addition to encapsulating the handle's opaque value, the
handle also contains a pointer to an "implementation", which can be used
to invoke methods on a device / device handle.

Device handles are designed to be passed around by-value.  It is expected
that any other memory objects they refer to will be durable.  They are an
aggregate type that consumes 2 pointers worth of storage space.

When device_t's are created, they initially have an invalid device handle.
It is currently the responsibility of platform-specific code to assign
device handles to device_t's.

When necessary, platform-specific code can override a handle's implementation
in a way that resembles sub-classing, such that specific methods can by
intercepted, but others simply passed through.  This also allows platforms
that do not otherwise have a platform description mechanism to provide
handle implementations in specific circumstances to describe the hardware
to platform-independent code.

A general device method calling infrastructure is provided.  Method names
that begin with "device-" are reserved for / defined by the autoconfiguration
subsystem.  Define the "device-enumerate-children" method.  Other subsystems
are free to define their own device method calls and bindings.

Welcome to NetBSD 9.99.80.

In device_is_a(), handle dev or dev->dv_cfdriver being NULL.  This
makes the calling pattern:

	device_is_a(device_parent(dev), "whatever")

safe.

The use of root_device is not limited to vfs, so don't supply it in
vfs_mount.c, use subr_device.c instead.

Fixes rump kernels built with DEBUG by again not making the base depend
on the vfs faction, as reported by Patrick Welche.

Device accessors are only marginally related to autoconf, so put them
into subr_device.c instead of having them in subr_autoconf.c.

Since none of the copyrights in subr_autoconf.c really match the
history of device accessors, I took the liberty of slapping (c)
2006 TNF onto subr_device.c.

Allow device_private(NULL), returning NULL.  It makes a lot of stuff

it will soon enough anyway.

Split off device-specific stuff out of subr_autconf.c, and split off
autoconf-specific stuff out of device.h.

The only functional change is the removal of the unused evcnt.h include in
device.h which (*sigh*) has side-effects in x86's intr.h, and probably some
other in the rest of the tree but I'm only compiling i386's QEMU for the
time being.
